Overview

Common Allergies in Dogs

According to the Aztec Animal Clinic, there are five basic types of canine allergies. Dogs typically react to allergens in much the same way as humans, with itching, scratching, sneezing and inflammation. If left untreated, however, your dog's allergy can lead to secondary infections, hair loss and digestive and respiratory difficulties.
Flea Allergy

If your dog is allergic to flea saliva, the tiny bites can cause intense itching, prompting your dog to bite and pull at the affected area, causing hair loss and secondary bacterial infections. Treatment includes corticosteroids, antibiotics for infection and, of course, strict flea control.

Bacterial Allergy

According to Paw Prints and Purrs, staphylococcus bacteria that normally live on canine skin can lead to staph infections in allergic dogs. Treatment includes antibiotics to heal the infection and staph antigens to boost your dog's immune system.

Common Allergies in Dogs
Inhalant Allergy

Like humans, your dog may be allergic to pollen, dust mites, mold or mildew. Symptoms of inhalant allergy are scratching, biting, licking and chewing the affected area, chronic ear infections, hot spots and skin infections. Treatment includes drug therapy, antigen therapy and medicated baths.
Food Allergy

Dogs generally develop food allergies in reaction to a specific protein component, such as lamb, beef or turkey. Symptoms include ear inflammation, itching, digestive problems and respiratory distress. Your veterinarian will most likely prescribe a specialized hypoallergenic diet for your dog.

Common Allergies in Dogs
Contact Allergy

The least common type of dog allergy, contact allergies are usually in reaction to flea collars or bedding material. Itching and irritation will occur at points of contact. Once the allergen is removed, the allergy will resolve itself.
