Coughing
-Temaril-P (Rx)
Question: Dear Dr. Mike:
Thanks for getting back with me regarding my dogs coughing. I
had not heard
about your suggestion to use a deworming medication. We live
in South
Florida, so I don't know if this is an area where lung worms are prevalent
or
not. Please let me know your thoughts on this for this region.
I still have
not gotten the culture back yet, hopefully today. It has been
6 days since
they did the culture from the tracheal wash, so I am hoping that something
has grown out by now.
I am still hesitant about using the corticosteriods if even for a short
term,
but if it is necessary, I will do it. What are the side effects
of using
Temeril-P on short terms as needed to control the coughing?
Thanks again for your help!
Julie
Answer: Julie-
I was not sure what the geographic distribution of lungworms were,
so I
looked them up in "The Textbook of Veterianary Internal Medicine" and
the
most common lungworms affecting dogs, Pargonimus kellicoti and Capillaria
aerophila are both found in the South. While looking this up, I noticed
that the dosage for fenbendazole (Panacur Rx) that they recommend is
25 to
50mg/kg every 12 hours for 14 days, which is a lot longer than we have
ever
used.
Temaril-P (Rx) is a combination of prednisolone and
trimeprazine. Prednisolone is a cortcosteroid and trimeprazine
is a
phenothiazine sedative. The side effects of corticosteroids include
increased drinking and urinating, increased appetite and sometimes
panting
or decreases in immune function. The side effects of trimeprazine include
sedation, depression, lethargy, decreases in blood pressure and
occasionally paradoxical excitement.
I have not used Temaril-P very much, because I don't like to use
combination medications when the two drugs have different dosing periods
when used separately. In this instance, the trimeprazine should be
used
four times a day when used alone and prednisolone should be used every
other day, when possible. A lot of veterinarians really like Temaril-P
and
seem to think it works better than either medication used alone, though.
It is probably OK to use Temaril-P for short periods. We just use
prednisone when it seems appropriate and it has worked well when it
was
necessary. I like to keep the use to less than five days or to
use it
every other day, whenever possible. If that is not sufficient to control
the coughing, the lowest possible daily dosage should be used or other
medications used, if possible. Sometimes a short course of corticosteroids
gives relief for some time, though.
I hope that the culture results were helpful.

Dry cough in Sheltie
Question: Dear Dr. Mike:
I am a recent subscriber to your service and am hoping you can answer
some
questions.
About 6 weeks ago, my 3 year old male Sheltie began having an occasional
dry
cough that was not productive. At first, I didn't think much
about it
because sometimes days would go by without any occurrences at all.
The
coughing started to become more regular (occurring about every other
day, 2-3
times per day). I have noticed that he sounds a bit congested
when he first
wakes up. Since he was a puppy, if he is outside running and
playing, it
always takes him much longer to catch his breath than my other Sheltie.
So,
because of these things, I took him to our vet who put him on antibiotics
in
case it was an infection. We compete in agility and are
at dog shows/trials
almost every weekend, so we thought he may have picked up some kind
of bug.
Both of my dogs are given Bortadella vaccines every 6 months because
of their
frequent exposure to other dogs. After completing the antibiotic,
the
coughing was still occurring, still only every other day or so.
I took him
back in and had a chest x-ray done. The Radiologist noticed some
inflammation on the film and said he had Allergic Pulmonary Disease.
The vet
(not our usual one, but one of his partners) wanted to put him on Temaril
P
but I said no because I didn't feel it was necessary to give a steroid
since
this problem was not chronic and the coughing wasn't happening on a
daily
basis. We tried TheoDur instead, but it didn't help. In
fact, the coughing
seemed to get worse after 2 1/2 days of treatment. I took him
back in this
week to have a tracheal wash. The cytology report shows nothing
abnormal and
we are still waiting on the culture report to see if there is a bacterial
growth present that the other antibiotic just didn't cure.
Do you have any other suggestions or ideas of what this can possibly
be?
Other than the coughing, he is acting completely normal and has tons
of
energy and enthusiasm. The congestion sounds are still occurring
when he
wakes up as is the coughing every few days or so.
I thought for sure it was going to be some kind of airborne allergy,
but
according to the cytology report, it isn't that.
Any information or suggestions you can give will be greatly appreciated!
Thank you in advance for your time and input.
Julie
Answer: Julie-
You are doing the right things to find out what is going on. We usually
go
ahead and use a good deworming medication, like Panacur (Rx), to try
to
rule out parasite migration and lungworms as potential causes of the
coughing but that may not be as likely in all areas of the country.
Sometimes it is possible to find the eggs of lungworms on fecal exams
but
not consistently, which is the reason for just trying the deworming.
I can
remember two or three patients whose coughing stopped quickly after
deworming.
We do tracheal washes at our practice. When we don't find a cause for
a
condition but feel that the problem really seems to be respiratory
and not
cardiac in origin, we sometimes refer patients for bronchoalveolar
lavage
(BAL), which is best done by someone with a bronchoscope, which we
do not
have. It is considered to be a better way to obtain cells for examination
and can allow a diagnosis when tracheal wash does not.
If the bacterial culture didn't grow anything it seems reasonable to
try a
short course of prednisone or the Temeril-P to see if it will have
a
beneficial effect prior to doing another invasive test procedure like
the
BAL, though.
We have a couple of patients with recurrent bronchitis that consistently
responds to antibiotics and about the same number of patients with
allergic
bronchitis that doesn't respond to antibiotics but will respond to
corticosteroids. It is hard to differentiate between these problems
and it
may take several attempts at tracheal wash or bronchoalveolar lavage
to get
a good idea of what is going on. Given your dog's age, it seems worthwhile
to try to get a definite diagnosis, if possible, though.
Good luck with this.

Chronic
coughing - Pom with hairballs
Question: Dr. Mike
I was just reading through some of your Q&A's on Pomeranians and
noticed an
article from someone named Christy 4-10-00 about her pom coughing excessively.
I have a 3 1/2 month old Pomeranian who has had a hacking, gagging
cough for
almost as long as I have had her,
almost two months. The veterinarian has given her three different
types of
medicines, and nothing has cleared it up.
It's been 3 months and she may have solved the problem by now, I don't
want
to seem intrusive but I have a Pom that had that bad coughing problem
right
off and at 4yrs of age still does without the proper treatment.
When my vet
first told me what to do I thought he was nuts but for the past 4 1/2
years
it's worked. HAIRBALL medicine. I don't know where he got
that idea, but he
told me to either buy hairball medicine for cats or smear some petroleum
jelly in her mouth so she has to swallow it (I didnt' care for that
idea, it
sounded nasty) Anyhow, when he first suggested this I took her to someone
else and my puppy suffered for 6mnths because of my disbelief.
The other vet
couldn't solve the problem, when I finally tried the flavored hairball
stuff
for cats it worked.
He said to be careful not to give her to much cause it will cause diarhea
but
we've got it down pat, started out giving it to her once a week. Now
is about
every 2-3 wks it seems to vary during seasons, but I can always tell
when a
dose is needed cause the cough starts back up. I'm not saying
she shouldn't
check for more serious problems, but if nothing else is discovered
she might
want to give it a try.
Thanks for your Time
Michelle.
Answer: Michelle-
I think that there definitely are some patients who cough (or possibly
retch in a cough-like manner) due to digestive problems rather than
respiratory problems. I haven't figured out a good way to tell which
ones,
yet. Trying a course of gastrointestinal lubricants, or medications
such
as cimetidine (Tagamet tm) or famotidine (Pepcid AC tm) seems reasonable
when the cough is chronic and non-responsive to therapy directed towards
respiratory disease. Perhaps your information may help someone else
struggling with this problem.

Coughing in small
dog
Q: Dr. Mike, the vets believe my 14-year old toy
poodle has Cushings disease. They did an ACTH stimulation test back in
January, but because Buffy was not in discomfort and because of the required
follow-up tests for medicating her, we decided not to treat her for it.
For a while she has had a "hacking" sort of cough, but now it sounds "croupy"
and she is having these attacks several times a day. The vet suspects this
may be a result of the Cushings and wants to do a broncoscopy (sp) to examine
her trachea. We are willing to start treating her for the disease, even
if it means she is traumatized by the overnight stays for the tests to
monitor the medication level. Is the brocoscopy necessary? Thanks for your
time. G.
A: The most common causes of coughing in older
small dogs are probably heart disease and collapsing trachea problems.
Sometimes there are other problems, such as cancer or pneumonia. I think
I would lean towards taking X-rays first since these are less invasive
and rule out more problems but perhaps your vets have already done these
or were planning to do X-rays at the time of bronchoscopy. If the X-rays
are not helpful in delineating the problem then bronchoscopy is a good
idea and can be very helpful.
Cushing's disease can contribute to heart problems and could cause coughing
to develop in that manner. It probably is not helpful in cases of collapsing
trachea, either, since it can lead to muscular weakness which could contribute
to the problem.
I am not sure why overnight stays are necessary in monitoring the progress
of treatment for Cushing's disease. We usually utilize ACTH response testing,
which only takes 2 hours. Your vet may have a different testing protocol
but you might want to be sure that overnight stays are part of the treatment.
Monitoring dogs being treated with l-deprenyl may be better accomplished
using the low dose dexamethasone response (LDDS text), which does take
a total of 8 hours.
In dogs in which monitoring Cushing's is a major problem it may be helpful
to consider treatment with either ketaconazole (Nizoral Rx) or l-deprenyl
(Eldepryl Rx) (not the standard treatments) because they do involve a little
less monitoring over time since are not as toxic as mitotane (Lysodren
Rx).
Hope this helps.
