Can my Dog Have Allergies?

With summer just around the corner there will be an increase in our pets showing common allergy related symptoms. Just like people, dogs can show allergic symptoms when their immune systems begin to recognize certain everyday substances-or allergens- as dangerous. Even though these allergens are common in most environments and harmless to most animals, a dog with allergies may have an extreme reaction to them. Allergens can be problematic when inhaled, ingested or contact a dog’s skin. As his body tries to rid itself of these substances, a variety of skin, digestive and respiratory symptoms may appear.

What Are the General Symptoms of Allergies in Dogs?

  • Itchy, red, moist or scabbed skin

  • Increased scratching

  • Itchy, runny eyes

  • Itchy back or base of tail (most commonly flea allergy)

  • Itchy ears and ear infections

  • Sneezing

  • Vomiting

  • Diarrhea

  • Snoring caused by an inflamed throat

  • Paw chewing/swollen paws

  • Constant licking

Allergic dogs may also suffer from secondary bacterial or yeast skin infections, which may cause hair loss, scabs or crusts on the skin.

Which Dogs Are At Risk for Getting Allergies?

Any dog can develop allergies at any time during his life, but allergic reactions seem to be especially common in Terriers, Setters, Retrievers, and flat-faced breeds such as Pugs, Bulldogs and Boston terriers.
