Canine Allergies
by Dr. Robin Goldblum
Dogs
itch. They chew their paws. That’s normal, right? Maybe not. Canine
allergies have become very common and are a growing problem as each season
passes. An allergy, also known as atopy, means that your dog’s immune
system is overreacting to substances that normally should not cause a
problem. These can include pollens, molds, grasses and house dust. Dogs
can also be allergic to different types of foods, wool, cotton, even
medications. Literally anything can become an allergen.
Certain dog breeds are
predisposed to allergies. Some of these include West Highland White
Terriers, Boxers, Golden Retrievers and Pugs. However, almost any dog can
develop allergies, including mixed breeds. Allergies can start in dogs as
young as 8-months-old, up into the senior years. A dog can eat the same
food for a decade and still develop an allergy to the ingredients contained
within it.
There are several signs
that can be caused by allergies. These include chewing the paws, rubbing
the face, recurring ear infections, anal gland issues, vomiting/diarrhea
(usually caused by food allergies) and recurring conjunctivitis (eye
irritation). However, there are some other medical problems that can cause
similar signs, like fleas, mites (Sarcoptic mange or Demodex), or bacterial
or yeast skin infections. This is why it is important to have a veterinary
evaluation.
One way to diagnose
allergies is to do allergy testing. There is some debate in the veterinary
world over the best method but 2 options are skin testing and blood
testing. These usually test for a large number of allergens which can help
determine the best course of action. Is your dog allergic to chicken and
corn? Then it is best to eliminate those from the diet. There are numerous
different types of prescription veterinary hypoallergenic diets that can be
tailored to a specific dog’s needs. Is your dog allergic to pollens and
grasses? Then you know that your pet is probably going to have problems in
the spring when all the plants are blooming. Unfortunately, the vast
majority of dogs are allergic to a combination of environmental, food and
indoor allergens. Whenever possible, the allergen should be eliminated from
contacting the dog. For example, hardwood floors would be a much better
choice for a dog with an allergy to wool carpets.
When elimination is not
possible, such as moving to the desert or the tundra to avoid environmental
allergens, medical treatment is usually necessary to keep the allergic dog
comfortable. Some dogs do well with just bathing twice weekly with a
medicated shampoo. Other dogs need antihistamines, like Benadryl or
Hydroxyzine. However, even though these tend to be the safest with the least
amount of side effects, a lot of the time they simply are not strong
enough. Many dogs have secondary bacterial or yeast infections that can
make allergy signs worse and need to be treated accordingly. We then turn
to medications like Prednisone, a corticosteroid that works wonderfully at
reducing the itching and inflammation but comes with its own set of problem
side effects. Atopica (also known as Cyclosporin) is another option with
fewer side effects but a higher price tag.
One treatment option that
has had very good success in human medicine is desensitization, also known
as allergy injections. The theory is that by injecting small amounts of the
allergen, the body can get used to it and learn not to over-react. It
usually starts with very tiny amounts and then increases over time. There
have been mixed results in the veterinary world. Some dogs do wonderfully
with desensitization and their allergies are practically cured. However,
some dogs do not respond at all and it never really helps them. There is no
way to know which dogs will respond without trying desensitization and it is
recommended trying this method for at least 2 years.
Sadly,
at this point, there are no known cures for canine allergies. Signs tends
to worsen as a dog ages, frequently starting as a seasonal problem and
developing into a year-round problem. The good news is with allergen
elimination and treatment, we can make these allergic dogs more comfortable
so that they can lead happy lives, even if they never become completely
itch-free.

Rabies Update!
To
the left is a map of all Rabies cases diagnosed in Pennsylvania
this year from Jan 1 through Feb 28. Of 30 documented cases, 3 were in Bucks County.
The Bucks County cases were all raccoons. Remember,
these are only cases that were actually tested. Many more went
undiagnosed.
UPDATE: During the 1st
week of February a rabid raccoon was diagnosed here at Indian Walk. It had
been killed by a client's dogs. All of that household's pets are now under
quarantine and the client is undergoing post-exposure prophylaxis.
Please remember, Rabies is
HERE!
Only by keeping all of your pets up to date on their Rabies vaccinations can
they and their human family members be protected from this deadly disease.

Happy Easter Happy
Passover!
