What
Dog breeds have black on their tongues
Question: Dr. Richards,
I volunteer for a no-kill animal shelter. We are often asked the breeds
of
the dogs we offer for adoption. Could you please clarify what breeds
there
are that might show black on their tongues? The only one I really know
of is
the Chow but I'm hearing form people that there may be others as well.
We
were given eight German Shepherd puppies recently and were told they
were
pure bred. Some of these puppies have black on their tongues. Is this
indigenous to the German Shepherd breed? Thanks for your input.
Joan
Answer: Joan-
Totally black tongues and gums are typical of chow chows and shar peis.
However, any dog breed that has black and tan, or predominantly black
coloring can have black spots on the tongue. We see this occasionally
in
German shepherds that are black and tan and frequently in rottweilers
and
Labrador retrievers. I'm sure that there are other breeds in which
the
black tongue spots occur, but these are the ones that come to mind
immediately.

Bad breath
Question: Dear Dr. Richards,
I recently (about 3 months ago) rescued an approximately 2 year old
lab
mix. He appears to be in good health overall now that we've had
him
fixed up and got some weight on him (he was starving and injured when
we
found him). However, he has VERY bad breath (kinda feces, garbage
bad-doog breath smelling). Overall, his teeth and gums appear healthy
and
clean, although he had some black discolorations on his tooth enamel
when
we first found him (has disappeared since). He also has moderate
to bad
flatulence. We are feeding him eukanuba large breed formula.
We
switched to Nutro large breed formula for a few weeks, but it didn't
help. His parasite tests have been negative, he has no diarrhea, but
his
stools are a little softer sometimes than my other two dogs.
I use
nolvadent dental gel on his teeth a couple of times a week and
occasionally brush them with a pet toothpaste but his breath gets bad
again soon after. His bad breath doesn't seem to be related to
his
eating anything in particular. We give our dogs very little besides
dog
food adn biscuits (Iams or Nutro usually) Can a sensitivity to
his
dogfood cause this along with his flatulance, or are there other possible
problems to look out for?
Thanks, Erica
Answer: Erica-
The most common causes of bad breath are the dental disorders. If there
is
no obvious tartar or gum inflammation, this may be less likely. Some
dogs
that chew on themselves a lot have bad breath from getting hair wound
around the tooth roots. If there is skin disease involving the lip
folds,
it can smell just like bad breath but actually be a dermatologic problem.
Dogs that eat feces (theirs or other animals) can have bad oral odors
as a
result of this habit. In people, gas from the GI tract is supposed
to be
responsible for some cases of bad breath, so there could be a correlation
between the soft stools, flatulence and oral odor. If deworming has
not
been attempted, even if there were no parasites found on fecal examination,
that might be a good first step. If that doesn't help, in this case,
I
would lean towards trying a food trial with foods that are not likely
to be
involved in allergic reactions. Currently the simplest way to do this
is to
feed Purina's HA (tm) diet or Hill's z/d (tm) diet. The other approach
is
to pick a food with a novel protein (one the dog hasn't eaten before)
such
as duck, ostrich, alligator, tuna, salmon --- just a protein source
that
your dog has not been exposed to. You have to feed these diets for
at least
4 to 6 weeks to see if they help. Your vet may feel that another diagnostic
test makes more sense first. These sorts of things are partly judgment
calls based on experience. Since your vet practices in the area you
live
in, trusting his or her experience makes more sense. There may
be other
tests suggested now or in the future. I will be glad to try to help
you
sort through them if that happens.
It is good that you are brushing his teeth some. Keeping that up is
worthwhile.

Enlarged
salivary gland or duct and possible acute gastritis
Question: Hello Dr. Mike. I am a new subscriber. I have been
enjoying the site for
months and I thought I ought to become a subscriber. I am a RVT on
leave to
raise the kids- this site keeps me in touch with work.
My questions concerns my 16 year old Doxie mix. She's got a lot of
old age
related problems- old kidneys, old liver, chronic back problems, cataracts.
Despite everything, she's really doing well. She loves life and is
still
feisty (she's got a lot of terrier in her!) The latest thing to come
us has
me worried. For months now she has been doing this awful retching thing
at
night that the sound cannot even be described. After the episode she
desperately needs to eat grass! Along with this came an exaggerated
swallow.(
she does this all day). After this went on for a while, I took her
in and we
scoped her. Nothing exciting, just what the doctor described as a
"hyperplastic airway". Maybe caused by allergies. We did nothing for
treatment (steroids are not an option with her weak kidneys). Shortly
after
the scoping, she started having a clear discharge from her left eye,
left
nostril and the left side of her mouth, especially after eating. The
horrible
sounds at night continue (about 3x monthly). Yet she continues to be
perky
and eat well. She has however gone from 16# to 12.8 in a little over
a year.
A few weeks ago she started having neurological signs-head tilt, limb
weakness, walking into things. I took her to a neurologist, thinking
maybe
she had a tumor causing the drainage problems that was now causing
neuro
problems. While waiting to get an appointment, my vet suggested stopping
a
course of Cefadroxil she was on for a UTI in case it was related. Well,
3
days later when I was the neurologist, she was almost normal-just a
mild head
tilt and still the draining eye, nose and mouth. He ruled out Hepatic
Encephalitis with an US and pretty much sent me on my way saying she's
got a
good quality of life for her age. I then took her to an ophthalmologist
who
discovered the enlarged Salivary gland (she gave it a name, but I don't
remember which) that was probably responsible for the drainage problems.
Now
my question-at her age, is it most likely a tumor? Or could it be a
blockage
of some sort? The last few days the odor from her mouth has been bad
and she
is not eating as well. I don't think I'm interested in surgery, The
scoping
was very hard on her and took her some time to recover from that. Oh,
by the
way, we also cleaned her teeth then and didn't see anything unusual
in her
mouth at that time. She's also back on antibiotics for her UTI. I just
want
to keep her comfortable. Sorry for all the rambling, but I wanted to
give you
a bit of background. Thank you. Sara
Answer: Sara-
Was this a ranula? That is an enlarged salivary duct under the
tongue. I
have a patient with one of these who has had it all his life and had
no
discernible problems. But I have had other patients have problems with
them, ranging from not eating to biting it and making it bleed.
An could be a salivary mucocele (sialocele), which
is basically a leakage of saliva into the tissues around a ruptured
salivary duct or salivary gland and the resulting inflammation. These
can
get abscessed at times and get pretty awful in a hurry. Opening them
widely
and placing drains usually will allow them to heal.
If a salivary mucocele occurs in the pharyngeal region it can lead to
a
harsh cough or retch and if it progresses it can lead to difficulty
breathing. In the whole time I have been in practice I only remember
one
time in which I was able to do an emergency tracheostomy and save a
patient
in respiratory arrest --- and that dog had a pharyngeal mucocele that
had
abscessed.
Sometimes there are enlargements of salivary glands due to tumors or
injury
to the salivary gland itself, too. I have not had too much experience
with
salivary gland tumors but they are easy to get fine needle biopsies
from
and the pathologists have been able to work with these, so far, in
our cases.
We have had a couple of dogs whose owners saw signs very similar to
those
that you are seeing, very loud, almost horrible sounding retching/gasping
that has been related to laryngeal paralysis. Usually, though there
are
other signs, like loud respiratory sounds most of the time, tiring
easily,
or coughing.
I have a couple of patients who seem to have really painful acute gastritis
that is unpredictable in its occurrence. They have had really loud
retching/vomiting and seemed to have pretty severe abdominal pain based
on
body posture and response to pain medications. We have treated these
guys
with famotidine (Pepsid AC Rx) or cimetidine ( Tagamet Rx), metoclopramide
(Reglan Rx) and pain relievers, usually mepheridine (Demerol
Rx) and have
had some success. I can't say that I know for sure what was happening
or
why the treatment worked, or even that it did work, since the episodes
weren't occurring constantly. But the episodes did stop and we
usually
have continued the medications, except the mepheridine, for several
months.
It does seem to me that it would be a good idea to get someone to look
into
the oral odor. If she will let you look around her mouth comfortably
you
could do that yourself. If she isn't comfortable enough to do that
and if
you think she would tolerate being masked down with isoflurane, perhaps
after sedation with acepromazine or diazepam and a narcotic agent,
like
butorphenol or oxymorphone, it seems like it would be worth it
to get a
good look.
If she continues to have persistant urinary tract infections it would
be a
good idea to rule out hyperadrenocorticism as an underlying cause of
that.
It is definitely pretty common in older doxies. Treating with selegiline
(Anipryl Rx) is much easier on older dogs than mitotane (Lysodren Rx),
so
it gives an option for treatment even in the dogs who might not be
able to
tolerate going through a whole lot of follow up testing during treatment.
Good luck with all of this. It is good that Bella has a good
attitude. That helps a lot when multiple problems are present.
Please feel free to write back if you get more information on the salivary
gland problem and need more specific information.

Masticular myositis
Question: Dear Dr. Mike:
My samoyed had a severe bout of masticular myositis last summer.
The
first sign I noticed was a slight yelp when she yawned. At the
time I
didn't know what that was about and when I brought her to the vet he
thought that perhaps she had injured herself and was simply sore.
Anyway, on to a terrible experience with locking jaw, severely swollen
glands, weight loss... etc. She recovered with aggressive treatment
and
was weaned off her prednisone (started at 30mg daily to every other
day
dosings with decreases at 20mg - 10mg - 5mg) gradually over a couple
of
months. She has been fine for the last couple of months and then
this
morning I noticed that she let out a slight yelp when she yawned.
Her
yawn is also slightly restricted.... not the usual open gaping yawn.
She is also making slightly noticeable grimaces with her lips.
I fear
it is returning and would like your sense on how to proceed.
Yes, I
will be calling my vet today but would like your opinion as well.
Should I put her back on the pred? Start with 5mg and work up
to
disappearance of these slight symptoms... or start with ??? and work
down.
Thanks in advance for your input.
P.
Answer: P.-
In a situation like this I would check for other potential causes of
pain
on opening the mouth, such as retrobulbar abscess, oral injuries or
foreign
bodies, swollen submandibular lymph nodes (or general lymph node swelling)
and dental problems. If nothing like this was present then I would
be
inclined to restart prednisone and I'd probably start fairly aggressively
--- the same sort of treatment regimen that worked the first time.
It is
possible that your vet may wish to try a different approach and since
he or
she can do an actual exam you have to put a lot more credence in their
advice than mine.
I hope that that this is a passing thing. I'm glad you already have
an exam
scheduled, though.
If this is a return of the myositis it might be necessary to consider
long
term low dose corticosteroid use. That isn't an ideal situation but
if you
and your vet work together to keep the dose as low as possible and
at the
longest possible treatment intervals (hopefully at least every other
day),
it is possible to use prednisone long term without major side effects
in
most dogs.

Spitting water
while drinking
Question: Hi:
I have a one year old female Beagle. About 90% of the time when she
drinks
water she spits some of it back up. This occurs whether she is staying
still
or playing. When she drinks after she has eaten, she still spits up
some
water, no food though.
I called my Vet and I will be taking her in next week to get checked
out. I
am writing to you because I can never have enough information. :-)
Thanks
J. K.
Answer: J.K.-
Spitting up when drinking water can occur for a number of reasons. These
include soft palate defects (cleft palate, palate fistulas, overly
long
soft palate, too short soft palate), laryngeal paralysis, myasthenia
gravis, pharyngeal inflammation, tonsillitis, megaesophagus and probably
other things that don't come to mind, right off.
In a young dog, soft palate abnormalities have to be the number one
consideration since most of the other problems are more common as dogs
age
or are less common. It may be possible for your vet to determine if
any of
these conditions are present by an exam under anesthesia. If your vet
isn't
comfortable evaluating the soft palate problems he or she may be able
to
refer you to a specialist in your area who is comfortable making these
evaluations. I have referred a couple of patients to veterinary schools
when I just couldn't be sure whether the soft palate was causing problems
or not. It is possible to evaluate the pharyngeal region and tonsils
during
the same examination.
If there is no evidence of that this is causing any significant problems,
such as nasal discharge, pneumonia, weight loss, etc., then it may
also be
reasonable just to live with the condition and not try to make a definite
diagnosis, or to put off trying to make a diagnosis until another condition
makes anesthesia necessary. If you are more comfortable knowing what
is
happening or if there are signs that it might be causing problems,
such as
nasal discharge, weight loss, changes in the sound of barking, coughing
or
pneumonia, then it isn't a good idea to take a "wait and see" attitude.
If examination doesn't reveal a problem, then tests like barium swallow
X-rays may help, if you wish to continue to pursue an answer.
Hopefully your vet will find something on the visit coming up. If a
minor
palate abnormality is present it may be possible to safely ignore this
problem. That would be the best outcome, probably.

Crying
after eating - differential diagnoses
Question: hi - i got into the cybervet because i have a 13 year
old westie who is
now crying after she eats. she walks around with her pillow in
her
mouth wailing for @ 15 minutes, no matter how much food i give her
(tsp
or plate). she has been to the dog psychiartrist in the past
for faking
limping, but i would never forgive myself if she had a stomache problem
and i dismissed it for that. also, she has a malignant tumor
in her arm
pit 1.5 years ago, so i wanted her checked out. my regular vet
in on
vacation until 8/11 so i took her to the associate who said she was
faking for attention. i am not comfortable with this, so i am
taking
her to the regular doctor when he returns. do you think this
is a real
problem? please help!!!
Answer: L.-
You should watch very very carefully for signs of swelling around
either
eye with the symptoms you are seeing. There are a number of potential
causes for pain around the time of eating but the most serious
one is a
retrobulbar abscess, or an abscess that forms in the space behind
the eye.
These can cause serious problems fairly quickly, including blindness
and in
severe cases, death. In most cases, dogs with retrobulbar abscesses
are
really pained by having their mouths opened -- some dogs refuse
to allow
this and others just scream when someone attempts to open the
mouth beyond
a certain point.
Our dog had a retrobulbar tumor and had similar signs -- but
she would
open her mouth part way before it hurt. She continued to eat
but sometimes
acted as if she was in pain afterwards. So this would be a concern,
too.
Dogs that have periodontal disease will sometimes have pain but
I can't
recall a patient having severe pain for fifteen minutes after
eating.
Dogs with marginal liver function can have behavioral changes
associated
with the period immediately after eating. In severe cases this
can cause
severe neurologic signs, including stupor or seizures.
Older dogs get a condition known as canine cognitive dysfunction
that can
cause odd behavioral signs. We have one patient in our practice
who wailed
for ten to fifteen minutes at a time, several times a day who
responded
well to selegiline (Anipryl Rx), the medication approved to treat
this
condition.
Gastic problems are conceivable, as well.
Westies are prone to craniomandibular osteopathy. If she had difficulty
with this as a puppy, there is some chance that she has arthritis
in the
mandibular joints now. This can happen without having the craniomandibular
osteopathy, too. Recognizing TMJ in dogs isn't easy, since they
can't
complain effectively.
I think that it is worth continuing to look for a medical cause
of this
problem, personally. I am sorry that the list of differential
diagnoses for
the symptoms is long enough to make it difficult to search through.
Please
keep checking to be sure she can comfortably open her mouth and
that there
is no visible swelling around one eye. If these signs develop,
don't wait
for your regular vet.

Response: what are you taking about!!!??? IF she
has all these problems? i
asked you a guestion. i guess i appreciate the care you took
in that
but aren't we getting a little carried away?!
Answer: L-
The only way to really figure out what is wrong is to consider all of
the
possible problems --- I don't think that all of them are likely to
occur in
a single patient but the big risk is not to think about one of them
and to
miss it because of that. Once a list of the potential causes can be
constructed then it is possible to eliminate individual potential problems
by the lack of supportive signs for that condition.
To give you an example, using the list that I constructed of possible
differentials:
1) retrobulbar abscess or retrobulbar tumor
is there swelling around
the eye? pain on opening her mouth?
if not, then these are less
likely
2) periodontal disease
does she have excessive tartar?
mouth odor? bleeding from her gums?
loose teeth?
if not, then this isn't too
likely
3) liver disease
do blood chemistry values
support this diagnosis? is she jaundiced?
if not, then this isn't
too likely
4) canine cognitive dysfunction
has she forgotten she is
supposed to go outside to urinate and defecate?
does she stand at the door
and go out and then come right back in?
does she forget about mealtimes?
have other odd behaviors that are new?
does she act confused or
vocalize for unexplained reasons?
if not, this diagnosis is
less likely
5) temporomandibular joint arthritis
this one is pretty hard to
eliminate without taking X-rays -- and even
then it can be hard. it
would be easier if dogs could talk, sometimes
if there is the perception
that pain exists, it may be beneficial to use
a pain relief medication just to see if it helps.
6) gastrointestinal disease
are there any other signs,
such as regurgitation, vomiting, diarrhea
weight loss?
if not, this is less likely,
too
It is likely that I have not thought of all possible problems --- but
the
point is that it is necessary to consider all of the problems that
could
lead to a particular clinical sign and then to eliminate them based
on the
presence or absence of other clinical signs.
I didn't mean to worry you --- just to tell you that I supported your
perception that there really could be a medical cause that may have
been
overlooked because your vet wasn't thinking about all of the possibilities.
It is hard in practice because we have to deal with a lot of variability
in
both the pet's ability to mimic illness and the owner's perception
of when
their pet is ill, which can vary widely. I have some owners who worry
easily and bring their pets in when they are just a little off -- and
other
owners who if they call me I know that their pet is already in the
midst of
a medical crisis. If your vet knows you well and thinks you are in
the
first category, then he or she is going to put less weight on your
perception of the illness and look for obvious clinical signs. The
problem
is that once in a while, your perception is going to be right when
the
clinical signs are slight ---- so you have to be willing to schedule
more
rechecks than the person who waits until their pet is actually bleeding
or
actually comatose prior to coming to the vet.
The thought process outlined above doesn't take very much time after
making
the list -- it is usually easy to eliminate many of the possible problems.
So I don't look at it as getting carried away but as being careful.
Sometimes when one of my clients has paid for X-rays and lab work and
a
couple of rechecks and I tell them I really think their dog is normal,
they
think I got carried away, though. Deciding how far to go in looking
for
problems is one of the things that makes veterinary medicine challenging
and difficult.
