Autumn brings many delights: colorful leaves, pumpkin-spiced everything, a reprieve from the heat of summer. For
pets with allergies, however, a change in season can also mean the onset of
uncomfortable itching and skin infections.
The idea that seasonal allergies are limited to springtime is a myth, according to Dr. Kimberly Coyner, a veterinary dermatologist at the
Dermatology Clinic for Animals of Tacoma. “Pets with fall symptoms are often allergic to weeds that pollinate in the fall, especially ragweed,” Dr. Coyner says. “Other weeds that can cause allergic reactions in the fall include sagebrush, Russian thistle (tumbleweeds), plantain, cocklebur and lamb's-quarters.”
Pets with environmental allergies, known as
atopic dermatitis or
atopy, can have symptoms limited to one season or can suffer year-round. “Animals can also be allergic to plants that pollinate in other seasons, including trees (springtime) and grasses (summer), as well as things that are in the environment all year round, such as house-dust mites and molds,” Dr. Coyner explains.
Many people miss the onset of allergic disease in their pet, because they are expecting their
dog or cat to start sneezing, as is often the case in people. “Dogs and
cats don’t usually sneeze or have runny eyes with allergies, which is called atopic rhinitis,” Dr. Coyner says. “More commonly, they scratch and lick or
chew their skin, often causing
hair loss, sores and secondary skin infections.”
While inhaled allergens can create issues for the pet's skin from inside the pet, those same pollens can also be causing damage from the outside. “Pollen grains are not only inhaled; they settle on the skin and fur and then trigger allergic reactions on the skin,” Dr. Coyner says.
Atopy can be suffered by both pets and people.
Itchy skin is the primary symptom noticed by owners, but more common signs of allergic disease are
itchy ears and recurrent
ear infections, Dr. Coyner says. Recurrent ear infections secondary to
atopy can occur even in the absence of any other signs of allergic disease, so many owners continue to treat the regular episodes without realizing there is an underlying cause that could be addressed.
For owners struggling to manage a pet with seasonal allergies, the good news is
plenty of options exist. The first step is a veterinary evaluation to ensure the pet doesn’t have a secondary bacterial infection that requires antibiotics. Most veterinarians start with milder drugs and work their way up if the medications aren’t doing the trick.
“In pets with mild symptoms or who have symptoms for only a few months out of the year, symptomatic medications may be all that is needed,” Dr. Coyner says. “Animals with seasonal allergies can be treated with medications to reduce
itching, such as mild anti-itch shampoos one or two times a week, antihistamines, and, in severe cases, occasional steroids.”
Though many pets respond to shampoos and antihistamines, more severely affected pets might require stronger therapies. Either immunosuppressants, such as cyclosporine, or desensitization therapy (injections or oral drops, which contain small amounts of what the pet is allergic to in order to retune the immune system) are often employed.
Eliminating the symptoms of allergic disease is the primary concern for owners, however, veterinary dermatologists such as Dr. Coyner regularly perform
allergy testing on pets to identify specific allergy triggers. Knowing the specific culprit can help owners minimize exposure of the allergen and reduce the pet’s symptoms. “Allergy testing and desensitization therapy can often be helpful to identify and treat the underlying cause of the itch, and reduce the need for symptomatic drugs,” Dr. Coyner says.
With so many options available, there’s no need for
your pet to itch and scratch his way through fall (or any season for that matter). If you’ve noticed a sudden onset of signs of allergic disease, head on over to the vet for a consultation.
