Goldens
and Allergies
Based
on lecture given to SEVA GRREAT Member Meeting by Dr. Gram, 11/2000.
The speaker at the November membership meeting was Dr. Dunbar
Gram, a Board Certified Veterinary Dermatologist. He sees plenty
of Goldens in his work and passed on an incredible amount of
information to help us understand this common Golden problem.
There
are three types of dog allergies: flea, food, and atopy (i.e.,
inhaled). It is not uncommon for a dog to have more than one
type.
Flea
Allergies
Many dogs
are allergic to fleas but with the improvements in the past five
years in flea preventative (such as Frontline), this is not the
issue it used to be. In our area, it is recommended that you
treat for fleas year round and don't try to stretch out the time
between treatments. Signs of flea allergies are intense itching,
usually on the rump. The best policy for this type of allergy
is avoidance. Treatments typically involve de-fleaing and steroids
to stop the itch. Note that your un-treated cats can act as a
"Typhoid Mary," bringing in fleas and exposing your
dog, family and home to fleas.
Food
Allergies
Food allergies
usually come from a reaction to your dog's protein sources. It
is obviously a year-round problem but diagnosing it can be tricky
since the dog will often have seasonal atopy allergies as well.
The best time of the year to test for food allergies in Tidewater
starts around Halloween. Dr. Gram also reports that skin or blood
testing for food allergies is essentially useless - only a restrictive
diet test works. Testing by restricting the diet needs to be
done for up to 10 weeks and includes all treats and even heartworm
treatment - no cheating allowed! Restrict your dog to one type
of protein they don't usually have and then at the end of the
test period, re-introduce the suspected protein and see if it
triggers allergy symptoms. The best policy for dealing with a
food allergy is avoidance as it responds poorly to medication.
Atopy
Allergies
Inhaled
airborne allergies are the most common allergy type. In Tidewater,
we have an unusually high number of inhaled allergens, so many
in fact that we rate our own special "disease" in the
vet medical journals - "Tidewater Crud." Our area has
a unique mix of the heavy pollens that are found in the north
and the light, easily wind-blown pollens found in the south,
all mixed together in a highly humid breeding ground for mold,
fungus and dustmites, all which occur for an extended season.
Tree pollens are most heavy in the spring, then molds and flowers.
Grasses peak around July, then weeds. Dustmites are also major
problem year round but peak with high humidity.
Avoidance is your best way of dealing with atopy. Your dog's
bedding should have no natural fibers. (Note: if you must use
cedar beds, the cedar should be changed every other week to avoid
mold growth.)
If your
dog is allergic to dustmites, note that cleaning does not help.
There are no effective chemicals for dustmites. Hypoallergetic
covers, washed in hot water, are your best bet. Dustmite concentrations
are highest in the areas of highest use such as couches and bedding.
Fungi
and mold allergy sources are surprisingly common indoors as well
as outdoors. Try to remove anything that is particularly subject
to decay such as burlap, wicker, bark and firewood. Restrict
your dog from going under decks and playing in woodpiles.
Maintenance
treatment for a dog with atopy allergies consists of regular
daily antihistimines (may only be needed seasonally) and with
oral steroids on an every other day basis as needed for itching.
For long-term maintenance, rotate the type of steroid. There
is some evidence that adding fatty acids, such as Derm Caps,
may improve the effectiveness of treatment.
Recognizing and Treating Allergies
If your
Golden is at least a year old, has three of the following signs
and they are reoccurring and improve with steroid treatment then
you can assume your Golden has treatable allergies.
- Discharge
from eyes (eye "goop")
- Discharge
from nose (runny or crusty nose)
- Dark
brown or black waxy discharge from ears
- Excessive
itching/chewing/scratching especially the feet (toes, nails or
hair between) and "armpits"
- Lick
granuloma
- Rubbing
face excessively, especially around mouth and nose
- Skin
and/or ear infections
- Yeast
infections of ears or feet
- Darkened
skin, especially on belly
- Scaly
skin, bumps or rashes
- White
roots
Symptoms
may be seasonal or year-round. If symptoms are seasonal, lasting
three months a year, consider treating with antihistimines and
oral steroids just for that period.
First,
make sure that your Golden is protected from fleas. If you still
have symptoms then try restricting their diet to a single new
protein source for 10 weeks. If symptoms are gone, re-introduce
old food to check for reaction. If flea and food allergies do
not seem to be the problem, talk to your vet about determining
the source of your Golden's symptoms. Your vet will be able to
rule out other conditions that are confused with allergies: contact
dermatitis, scabies mange, folliculitis and parasites. If your
Golden needs an allergy skin or blood test, be sure that enough
time has passed since their last dose of antihistimines, steroids
or sedatives so that test results are not thrown off.
Allergy
shots are an option if you can not avoid the allergen and you
are unsuccessful at treating your dog with medication. Shots
may be needed 15-30 times a month, may take up to a year to see
results, and a maximum of 10-12 specific allergens can be addressed.
Reactions to shots are possible but very rare. If after three
months on shots, the dog is still suffering, go to the vet and
treat symptoms-don't let them suffer. If there is no improvement
in a year, re-evaluate.
