There is a veterinary phenylpropanolamine product available called Proin (Rx),
for the treatment of incontinence in dogs. This is not a new drug but was
previously a human drug now removed from the market . The side effects phenylpropanolamine
like high blood pressure problems
reported in humans that caused the human product recall have not been shown to occur in pets.
Phenylpropanolamine has been used for many years to successfully treat
incontinence
in dogs. There were several years that it was not available when the FDA
removed the human drug and it had to be reconsidered as a veterinary drug.
Other treatments options were and are available and are sometimes still
used - you will see below.
Incontinence
treatments in male dogs
Question: Dear Doctor,
I've been a subscriber since February. My question involves
our 19 month old neutered
Labrador Retriever. We have recently noticed that he is
leaking urine....it does not happen
on a regular basis and does not seem to necessarily coincide
with excitement or a full
bladder. We noticed his bedding was damp at times and
just thought that it was from his
licking himself. He does not urinate more frequently than
normal. I read the information on
incontinence you have in the alphabetical index and obtained
a urine specimen from him this
morning which I will take to my vet for analysis. I am
curious about the testosterone
injections that were mentioned and want to know if there are
any side effects with them as
with bone marrow suppression with DES injections for females.
Thanks for any information
you can give.
Sincerely,
Phyllis
Answer: Phyllis-
The use of testosterone for incontinence that occurs after neutering
does not have the risk of
bone marrow suppression that the use of estrogens in females can have.
It is not without the risk
of side effects, though. Dogs supplemented with testosterone may exhibit
an increase in urine
marking and aggressive tendencies. While urine marking may be viewed
as an inconvenience by
some owners rather than a serious problem (although many owners will
find this a serious side
effect), an increase in aggressive tendencies can be life threatening
to the pet. I am not aware of
an oral testosterone product, usually testosterone cypionate is given
by injection once a month.
Phenylpropanolamine works for many male dogs and there is a veterinary
phenylpropanolamine
product available, Proin (Rx), even though the human products are all
gone from the market at
this time. To the best of my knowledge the high blood pressure problems
reported in humans
have not been shown to occur in pets and we have used this medication
for a long time without
significant side effects, as well.
It would be a good idea to try to rule out neurologic causes for the
urine leakage, especially if
there are any other signs of neurologic problems, such as weakness
in one or both rear legs,
improper foot placement or a drooping tail. In addition, making
sure that a urinary tract
infection or disorder is not present is also a good idea. The odds
probably favor a decrease in
urine sphincter tone (the form of incontinence associated with decreases
in the reproductive
hormones) but it is still a good idea to be careful not to miss another
cause.
Good luck with this.

Incontinence
Question: I'm not up on medical lingo, so bear with me.
my black lab mix Abbey has had a problem with leaking urine.
It literally
drips out of her at this point. It started out as an intermittent problem.
We have taken to the vet several times for this. He has put her
twice on
medicine(it's the one that was in cold medicines for humans until it
was
recalled). He also suggested it might be a bahavioral problem.
Her urine
was tested , and came back negative, although it was somewhat diluted.
The
other option I was given was to put her on hormones, but I really don't
want
to start a 1& 1/2 year-old dog on a lifetime of hormones, and their
side-effects. We are really at our wit's end here--is there such
a thing as
a doggy urologist? We live in upper New York, are close to Connecticut,
but
are willing to travel to solve this problem for our dog( she
is just
miserable). Where could we find a top-notch animal hospital,
or specialist?
In addition, Abbey was diagnosed with hip dysplasia around her first
birthday. Unfortunately, she was too old for the surgery that
can correct
this problem at that age( it's not hip replacement, but the newer option)
She has been on Cosequin, with great results. She runs, jumps, and
behaves
perfectly normal. I only mention this because I wonder
if the two could
possibly be related?
Any suggestions you can give me are greatly appreciated. I use
your site
often for information.
Thank you, Dagmar
Answer: Dagmar-
Incontinence can occur for a number of reasons. In a young dog, it is
helpful to try to be sure that there isn't a cause for the incontinence
that can be cured, prior to treating it symptomatically. Your vet may
already have made an effort to do this, or it may be necessary to seek
the
help of a specialist.
Incontinence can occur because there is an increased urge to urinate
that
the dog can't control, when there is a decrease in the ability to resist
urine flow for hormonal, neurologic or anatomical reasons and occasionally
as a behavioral problem. Of these, hormonally responsive incontinence
is
the most common cause.
If the phenylpropanolamine (PPA) was effective when you were using it
but
the incontinence returned, hormonally responsive incontinence is the
most
likely problem. If it did not help at all, the failure doesn't rule
out
hormonally induced incontinence, though. Some dogs do require estrogen
replacement therapy. Usually it is possible to use low enough dosages
that
adverse side effects are unlikely. I really can't remember having a
serious
problem from the use of diethylstilbestrol (DES) for incontinence,
but we
have had some problems with other estrogens, so there is some reason
for
concern when using estrogens. Phenylpropanolamine is available
under the
brand name "Proin" as a medication for dogs.
If the PPA was not effective, it would probably be a good idea to see
a
specialist to try to get a complete work-up to rule out non-hormonal
causes
of incontinence such as misplaced ureters, bladder stones, chronic
lower
urinary tract infections and neurologic problems. It may take dye contrast
X-rays of the urinary tract to establish that the system is anatomically
correct and functional, culture and sensitivity testing of urine extracted
directly from the bladder, X-rays for bladder stones and a general
work-up
to rule out other systemic problems in order to feel comfortable going
ahead and using hormonal therapy.
Unfortunately, I am not able to tell you who does this sort of workup
in
your area but the veterinary schools (Cornell, Tufts) are usually a
good
choice and there seem to be several referral centers in the New York
area
(the Animal Medical Center in Manhattan, for example). Your vet can
help
you find a specialist and most are happy to do this.
I couldn't find any information that suggests Cosequin (tm) or other
glucosamine/chondroitin products lead to incontinence. We have seen
several
dogs with severe hip dysplasia who we think would urinate where they
were
laying because getting up was too painful. We believe this to be the
case
because pain relief or hip replacement therapy ended the problem in
these dogs.
Good luck with this. Don't rule out using estrogens entirely. We have
found
them to be useful and not very likely to cause problems, so far. Checking
to be sure estrogen therapy is necessary is a very good idea, though.

Treating incontinence
in dogs
Question: Dear Dr; I have a dog with spayed female
incontinence. For over a year I have treated her with ppa (acutrim) with
total success. Unfortunately, this drug is now unavailable. Hormonal tx
is out of the question since she has liver disease. My vet has no answer
for me, and I am at my wit's end. Any suggestions? Thanks in
advance Annette
Answer: Annette-
I am sorry for the delay in replying to your question. There are several
medications that are currently
being used to treat incontinence in dogs in an effort to find one that
replaces phenylpropanolamine
(PPA). They are:
1) Diethylstilbestrol (DES), which is a synthetic form of estrogen.
There is some fear of bone marrow
suppression when using DES but I do no recall ever experiencing this
problem in practice, so I
presume it is rare. I know of no reason that DES can not be used when
there are changes in liver
function, but your vet may know something that I do not. DES is currently
only available from
compounding pharmacies but all the ones that we deal with have it,
so it is readily available.
2) Imipramine (Tofranil Rx), a tricyclic antidepressant, causes urine
retention in some patients treated
with it, so it is being used in the hopes this effect will occur in
patients with incontinence. Initial
reports are encouraging, but that is often the case when people are
looking for a substitute for a
medication and want to have good results.
3) Pseudoephedrine (Sudafed tm) causes similar effects to phenylpropanolamine
but has not been
used extensively. The dosage is 30mg for small dogs and 60mg for big
dogs. I have been using 30
lbs. of bodyweight as the dividing line between large and small. I
have not had enough reports back
from owners yet to know if this is working at all.
4) Some compounding pharmacies still have phenylpropanolamine powder
and can custom make
capsules with the appropriate dose for a patient who needs this medication.
It is worth calling around
to the various compounding pharmacies (or checking online for veterinary
compounding pharmacies)
to see if one of them has this medication. Your vet should know of
some of these, as well. There are
several that advertise nationally.
Good luck with this. I hope that one of these suggestions is helpful
if you have not already found a
solution to the problem.

Phenylpropanolamine's
alternatives
Question: Hi, Dr. Mike -
I'm sure I won't be the first, nor the last, of your clients/correspondees
to ask just what you will recommend to take the place of the now-defunct
phenylpropanolamine. I am just sick that I can no longer obtain
Dexatrim,
or other OTC meds, to control BOTH Trudi's and her Boxer-sister-Fanci's
(Fanci's is the typical spayed-female-leakage, brought on by advancing
years) incontinence.
A brief note on our CRF gal, Trudi. Twenty-two months after the
original
diagnosis of chronic CRF was handed down, she is still doing remarkably
well. The herbal iron tonic I discovered about 4 mos. ago has
really
created a huge improvement in her looks, stamina, eating patterns,
demeanor. We continue to have small episodes of pancreatitis,
which (so
far) can be controlled by removing all food for 24 hrs. Strangely,
although she LOOKS so great, her blood chem values have changed
little; outwardly, the only sign that she's a CRF gal is her
constant-and-profuse shedding.
Dr. Mike, I sure hope you'll be able to give us a tip as to what (either
OTC or Rx) we can use to control the incontinence from now on.
Thanks in
advance.........your advice has always been valuable to us!
Regards, Rozanne
Answer: Rozanne-
Phenylpropanolamine is still available from some compounding pharmacies.
I
know of at least two in our area that still have the powder to make
this
medication and I believe that it may remain available through compounding
pharmacies.
There are alternatives to phenylpropanolamine. The one currently being
talked about the most on the Veterinary Information Network (www.vin.com,
a
service for veterinarians only) bulletin boards is impramine (Tofranil
Rx),
1 to 2mg/kg of body weight every 12 hours, up to 15mg twice a day.
I have
not used this medication because we have had good success using
diethylstilbestrol (DES) and have been able to obtain this medication
from
our local compounding pharmacy. We usually use 0.5mg per day for 5
days for
small dogs, or 1mg per day for large dogs. We then try to lengthen
the
interval, usually reaching a once weekly or twice weekly dosage in
most
female patients. We usually try testosterone in male dogs but generally
have to combine this with something else, such as phenylpropanolamine,
so
when our supply of this runs out, we will have to consider other options
for our male patients, probably. I am hoping that when we run
out of
phenylpropanolamine the compounding pharmacies will still be able to
get
the medication.

Leaking
urine and accidents - medication related in Samoyed
Question: Help! My samoyed has suddenly forgotten what
it means to be house
trained. She is currently on medication for myositis, predinose
30mg
every other day, and when she started to leak urine, she was put on
phenylpropanolamine (now down to 25mg on the days she gets her
prednisone). In the last week, she has started to have accidents
in the
house, even after she is brought in after being out for a while.
I let
her out several times during the night and still she slips. Is
this
related to the medication?
Thanks. P.A.
Answer: P.A.-
It is very likely that there is a relationship to the medication with
the
sudden change in urinary habits. Sometimes prednisone can make it easy
for
bladder infections to occur, so it would be worth having her checked
by
your vet for this. Bringing a urine sample that is less than 4 hours
old
can be helpful, just in case it isn't possible to get a urine sample
at the
vet's office. Prednisone can also sometimes push a dog with a tendency
towards diabetes into exhibiting signs of that disease and the urine
will
help to rule that out.
If the urination problems are not related to cystitis there is still
a
chance that the prednisone is contributing, since it does make dogs
drink
more and urinate more. In that case, it may be necessary to try to
find a
lower dose that will control the myositis but not induce excessive
urination. Sometimes it isn't possible to do that but it is worth trying.
Sometimes when dogs start to have accidents in the house for medical
reasons the behavior becomes self supporting since dogs like to urinate
where they have urinated before. Cleaning the area carefully with an
enzymatic cleaner and working hard to catch her urinating so that you
can
reinforce that it is not acceptable behavior with a loud "NO" can help
to
restore her old and better habits.
Good luck with this.

Incontinence
in older Ibizan Hound
Q: Dear Dr. Mike,
I have a ten year old female ibezan hound who was spayed three years
ago. This morning she was lying on the couch, and I was petting her. When
she got up, there was a small puddle of urine. She is totally housebroken,
and had just been walked, so I was very surprised and concerned to see
this. To my knowledge this has never happened before, and we were recently
at the vet who gave her a clean bill of health. Your input on this
matter would be greatly appeciated. Thank You A. K.
A: A.K.
Incontinence is not unusual in older female dogs. It is probably occurs
at a slightly younger age in spayed females and may be a little more common
in them. The history is typically exactly what you have seen, urine leakage
while laying down or while asleep. It is best to rule out bladder infections
and causes of increased urination such as diabetes and Cushing's disease
as contributing factors. Your vet may feel that this was accomplished during
the recent exam but it would be best to check with him or her on this.
Incontinence responds well to treatment in most cases. Usually the first
medication tried is phenylpropanolamine but estrogen supplementation is
sometimes also used first. Whichever medication is used, the other one
is available if there is treatment failure. In many instances we find that
treatment for a couple of months will often stop the problem for some time
and that going on and off of medications doesn't seem to make them less
effective when it is necessary to use them again. Let your
vet know this is happening and I think you'll find that treatment works
well.

Incontinence
- possible causes in Golden
Q: Dr. Richards
I was reading the letter from Maggie about her 2 year old Golden Ret.
who
has been suffering with incontinence. Our 6 yr old JR terrier
had the same
problem as a 3 yr old and we pursued the same suggested treatment as
Maggie's vet prescribed, with no results. We decided that we
would have to
live with the 'leaking' and proceeded to 'waterproof' the house as
much as
possible.
However, after a few years of other medical problems, we recently found
that Charlotte suffers with liver shunt and hydrocephalus. But
during our
exploration of her liver problems, the surgeon discovered a kidney
stone
blocking one of her ureters. The stone was removed during exploratory
surgery, and since that time there has been no more urine 'leakage'.
I am
confident that the stone may have played some part in that problem.
Is it
possible that stones can be transient enough to sometimes cause this
situation? We treated Charlotte at various times for what we
suspected as
urinary tract infections, on the basis of urinalysis results. Can existing
stones be a cause of the positive test results? Thanks for your
expertise.
Maureen
A: Dear Maureen-
There are a number of possible causes of incontinence. Small stones
in the
ureters, bladder or urethra can definitely cause signs of incontinence.
It
is conceivable that there could be recurrent episodes of incontinence
associated with stones from metabolic causes, such as urate stones.
These
tend to be formed in larger numbers than struvite stones and it is
not
uncommon to find hundreds of small stones when these are present.
Incontinence is commonly encountered in veterinary practice. The majority
of cases are probably estrogen responsive incontinence. In a spayed
female
dog in which incontinence shows up after the surgery it is very tempting
to
ignore other possible causes and treat for this one. Especially since
it
can be pretty expensive to test for all possible causes. In a dog in
which
incontinence is not responsive to therapy or when there are reasons
to
suspect other causes may be present it is important to know what else
can
lead to incontinence and to eliminate as many of them as possible through
appropriate testing.
It is important to consider several different things when dealing with
incontinence. As a first step it is important to establish that the
problem
really is incontinence and not just an increase in the need to urinate
causing the dog to urinate in the house because it has to. Disorders
that
increase the amount of urine produced and therefore the need to urinate
include diabetes mellitus, hyperadrenocorticism (Cushing's disease),
diabetes insipidus, uterine infections, kidney failure, administration
of
corticosteroids and some other medications and other more infrequent
causes. It is important to let your vet know if your dog is drinking
more
than normally and urinating larger volumes than normal. There are also
diseases and disorders that increase the urge or need to urinate without
an
increase in actual urine volume. These include cystitis, bladder stones
or
stones elsewhere in the urinary tract, cancer in the urinary tract
and
prostate disease in males.
There are also a number of disorders that are considered to be forms
of
incontinence that are not related to estrogen levels. Neurologic disorders
affecting the nerve supply to the bladder can lead to incontinence.
There
are several classes of these disorders. In general the bladder is large
and
distended due to the loss of nerve function. This is a hint that there
may
be neurologic causes. Many practitioners do not feel confident in their
ability to diagnose neurogenic bladder disorders and if they are suspected
it may be necessary for a neurologist to help in the diagnostic process.
Large bladders can also be a sign of an obstruction to urine flow beyond
the level of the bladder, such as a urolith (stone) in the urethra,
especially in a male dog and cat.
Some dogs are born with their ureters, the tubes that connect the kidneys
to the bladder, misplaced. When this happens it may lead to continuous
urine leakage, especially if they miss the bladder entirely and implant
directly into the urethra.
There are also dogs with behavioral incontinence. Stress or excitement
can
lead to urine leakage. Another behavioral condition some dog owners
confuse
with incontinence is submissive urination. This is a form of voluntary
urination, so not truly incontinence, that occurs when a dog is very
submissive. These dogs usually roll over when approached, show their
undersides and urinate a little or sometimes a lot.
This isn't really about incontinence, but urate stones are fairly common
in
dogs with portosystemic vascular shunts. It is probably a good idea
to
consider the possibility of these stones in any dog with liver shunts.
Any
bladder stone can cause or make it seem like cystitis or incontinence
is
present, both by mechanically obstructing the urinary tract and by
irritating it and creating a better environment for bacterial infection.
I am glad you thought to write about this. It is good to be reminded
to
think about all the possible problems that can lead to any particular
sign
or syndrome sometimes.

Urine leaking in Golden
Q: Hello, I have a problem with my 2 years old
female golden retriever (spayed
around 6 months of age). I notice when she is asleep that she is leaking
urine. It started while she was on antibiotics Apo-Sulfatrim 480mg
due to
an ear infection (I though it was a side effect). There is no bladder
infection.
My vet is convinced that this is incontinence and suggested the use
of
ESTROGEN SUPPLEMENTATION. I heard that this medication can cause serious
side effects.
I'm looking for a homeopathic treatment.
I would like to know if you have any suggestions.
Thank you
Maggie
A: Maggie-
I am sorry, but I have no experience at all with homeopathic treatment.
The two most frequently recommended treatments for incontinence in female
dogs are estrogen supplementation and phenylpropanolamine (Propagest
TM,
Dexatrim TM).
The most successful estrogen supplement was diethylstilbestrol (DES),
which
is currently hard to find. Estrogens do not cause side effects with
great
frequency but the side effects can be very serious, including suppression
of the bone marrow's ability to produce red blood cells that may not
respond to withdrawal of the medication. We never experienced this
side
effect in our practice but it was worrisome enough that we preferred
to
attempt treatment with phenylpropanolamine first whenever possible.
We have
not had much success with alternative estrogen products that have been
suggested since DES has become harder to find.
Phenylpropanolamine is a decongestant and is the active ingredient in
Dexatrim (TM), the product used for appetite suppression in humans.
As far
as I can tell there is no appetite suppressive effect in pets. It does
not
seem to have serious side effects but it often has to be given three
times
a day to be effective and that is a drawback for many pet owners. Sometimes
it works for the majority of incontinence when it is given at bedtime
since
many dogs are only incontinent when they are sleeping.
There may be herbal or homeopathic treatments for this problem. If you
have
an interest in them, there are veterinarians who use these treatment
methods in their practices.

Incontinence after
neuter
Q: I am in search of solutions to two problems
that I am having with my 10 month old male pug "Pepper Boy". He is having
a urine leak from his penis since approx. 1 month after he was neutered
at 8 months. My local Vet. gave him a 2 week supply of antibiotics but
this did not clear up the problem. The second problem is a bald spot that
has developed on his shoulder. We have tried various creams but these have
not helped. The Vet. thinks it is a fungus but can not rid him of it. Any
help you could provide in solving these problems would be greatly appreciated.
A: I guess I would be suspicious of hormonally
based incontinence in a dog that developed urine leakage after neutering.
Usually this will not occur this quickly and it isn't a common problem
in male dogs but it just seems like a reasonable possibility once infection
seems unlikely (the reason for the antibiotic treatment first). It is usually
responsive to treatment with testosterone replacement and sometimes only
a couple of injections are necessary to stave off the problem for long
periods. It might be a good idea to take bladder X-rays to rule out bladder
stones and consider a general chemistry panel to rule out causes of increased
urination before attempting incontinence treatments.
If your vet has taken skin scrapings from the sore and not found parasites
then I have no other good suggestions for diagnosing this problem other
than considering a skin biopsy if it won't clear up. They can be very helpful
in difficult cases of skin disease.

Urinary Incontinence
in Rottie
Q: Dear Dr mike, My female Rott is a year
old and she is house broken, and when she sleeps now we see on her bed
it is wet so i have been watching her and she didn't do this before, what
could be wrong with her, could she have a cold ?She dont have any thing
else. thanks
A: Your dog probably has urinary incontinence.
This is an inability to hold urine in the bladder. When dogs urinate where
they are sleeping or particularly if they urinate when laying down and
awake, this is the best possibility. It is important to rule out a bladder
infection, bladder stones and diseases that cause increased production
of urine, such as diabetes before deciding that incontinence is the cause
of urine leakage. In addition, there are several causes of incontinence,
which respond to different treatments. In almost all cases, it can be controlled,
though. Your vet can help with this problem, almost for sure.
Dimetapp
tablets for incontinence
Q: Dr. Mike, In the case of urinary incontinence,
what do you think of the use of Dimetapp extentabs (twice daily if necessary
12 hours apart). ????
A: Dimetapp tablets contain phenylpropanolamine
and a second ingredient (brompheniramine) which probably isn't necessary
to administer but also probably isn't harmful. It is usually less expensive
to use phenylpropanolamine (generic of Propagest Rx) by prescription just
because of marketing/packaging costs but if it is more convenient to use
this formulation and the antihistamine doesn't cause drowsiness or other
side effects I see no reason not to.
Mike Richards, DVM
Leaking urine
Q: Hello, Having a problem with my female German
Shepherd - she is a little over 7 years, been spayed around 6 months. I
notice when she is asleep that she is leaking urine, she also urinates
quite a bit outside especially before I start throwing her toy for her.
She was overweight so I have had her on a diet and she has lost a few pounds
and at least has a waist now. She drinks a lot of water and is always warm
(panting). I was wondering if the spaying could have damaged the muscle
that controls her bladder. We have noticed quite a few wet spots where
she lays and it seems to happen only when she is relaxed and asleep. She
has a normal appetite, looks healthy and is energetic. I would appreciate
your comments. Thank you
A: Spaying does not damage the urinary sphincter
muscles, to the best of my knowledge. It does cut down on the estrogen
levels in the female dog's body, though. This can lead to a loss of muscle
tone and possibly mucosal thickness in the bladder, which does often lead
to incontinence. Most dogs with this condition will respond to estrogen
supplementation, usually using diethylstilbestrol (DES). Many vets prefer
to try phenylpropanolamine (Propagest Rx, Dexatrim Rx) first, though. This
medication is less likely to cause side effects than estrogen supplementation.
Some dogs require both medications.
The most serious side effect of DES is bone marrow suppression. I think
this must be pretty rare because we have used this medication in our practice
for eighteen years now and have not seen this in any of our patients. We
have seen it using other estrogen products and feel that it has to be considered
as a risk due to those experiences, though.
I do not know the percentage of spayed females with this trait and it
does occur naturally in older female dogs who have not been spayed. It
does appear to happen more commonly in spayed females, though.
There are a also a number of neurologic causes of incontinence. It is
important not to overlook any evidence of neurologic disease in an incontinent
dog. Also, it is important not to overlook causes of increased urine production
that may be contributing to an incontinence problem. Diseases like diabetes,
hyperadrenocorticism and kidney failure can all cause an increase in drinking
and urine production which can show up as incontinence in a dog that previously
did not have problems with urine retention.
Hope this helps.
Mike Richards, DVM
Incontinence
in a 7 year old Pug:
Q: Dear Dr. Mike: We have a 7 year old male pug
that has developed incontinence recently. Our vet has been treating
for bladder and kidney infections with various medications for several
weeks but the problem continues. The vet seems to be stumped by this
and we would like to know if you have any suggestions. Thanks.
A: It sometimes takes a little while for a vet
to become convinced that incontinence really is incontinence, especially
in a young or middle-aged dog. Usually we try to rule out bladder infections,
bladder stones, neurologic disorders, hormonal disorders that increase
urine output and all other possible causes of urinary problems that we
can eliminate before giving up and accepting that incontinence is present.
I can't fault this approach because most of the time I do the same thing.
Often, we will try antibiotics to make sure that cystitis isn't present,
then suggest X-rays of the bladder and a general lab panel to try to rule
out obvious hormonal disease like diabetes. Bladder stones seem to be a
relatively common cause of incontinence in male dogs in our practice. Sometimes
the history is so strongly supportive of incontinence that we go right
to exploring the possible causes of it first - neurologic and hormonal
disorders being the most common causes of incontinence in dogs.
Once your vet is convinced that this is incontinence and not something
else, he will probably try hormonal therapy if no obvious neurologic disorder
is present. In male dogs, this is usually testosterone by injection since
a convenient oral form of the hormone isn't available as far as I know.
Most of the time the injections can be spaced around a month apart. If
neurologic signs are present, they will be treated based on exactly what
your vet finds. Good luck with this.
Mike Richards, DVM
Continued:
Q: Dr. Mike: Thank you for your response and advice
about our pug's incontinence. I have some more information that might be
helpful in discovering what is wrong with Wally. You will recall that he
is a 7 year old, male pug. The doctor has been treating him for three weeks
with no success. She says that he has blood in his urine as well as protein.
This would lead me to believe he has a bladder infection, but why doesn't
medication help? She x-rayed him and found nothing. Blood tests showed
that his white blood cell count why slightly elevated but nothing extreme.
Any more suggestions? Thanks!
A: I would be more worried about bladder stones
and bladder cancer in a dog that continued to have blood in the urine after
three weeks of antibiotic therapy. It is difficult for bacteria to resist
antibiotics in the bladder because the concentrations of antibiotics in
the urine are often many times the concentration of the antibiotics in
the blood, since they are often filtered intact through the kidneys, which
results in them being in urine in high concentrations.
The non-surgical approach is to consider either contrast X-rays (air
or a contrast solution can be injected into the bladder to help outline
stones that don't show on X-rays or a bladder tumor) or ultrasound exam.
The other approach is to consider exploratory surgery to see if a cause
of the problem can be determined. In our practice, which is pretty rural,
clients often elect to have exploratory surgery rather than traveling to
a specialist for ultrasound exam or paying for contrast X-rays when there
is a strong chance surgery may be necessary later. Avoiding surgery is
important to other clients and they opt for the more advanced testing procedures.
I hope you find a reason for all of this soon.

Incontinence in Akita
Q: My one year-old Akita has developed frequent
urination and a mild cough. Her urination is in small amounts and coincides
with coughing..This started when we came home from a hike in the woods.
She has not had any health problems and is spayed. Thanks.
A: I'm sorry, but this is a problem that you're
going to have to get your vet to resolve. It is possible that your Akita
is experiencing incontinence and some dogs do have more problems with urinary
incontinence after exercise or excitement. It makes some sense that coughing
might exacerbate a problem with incontinence but one is young for the problem
and it would be a good idea to have the cough checked out if it continues,
anyway. If incontinence is the problem it is usually possible to treat
it with estrogens or phenylpropanolamine, so your vet should be able to
help out.
