Dog Allergies | Allergies in Dogs
Allergies in dogs are basically an immune system overreaction. The nasal cavity is an uncommon primary site for allergic disease in dogs and it has not been well characterized yet. However, dermatologists provide anecdotal reports of atopic dogs rubbing the face (possibly indicating nasal pruritus) and experiencing serous nasal discharge, in addition to dermatologic signs. Dog allergies are generally considered to be a hypersensitivity response within the nasal cavity and sinuses to airborn antigens. Other antigens are capable of inducing a hypersensitivity response as well, and thus the differential diagnoses must include parasites, other infectious diseases and neoplasia.
Dogs with allergies experience sneezing and/or serous mucopurulent nasal discharge. Signs may be acute or chronic. Careful questioning of the owner may reveal a relationship between signs and potential allergens. For instance, signs of dog allergies may be worse during certain seasons; in the presence of cigarette smoke; of after the introduction of a new brand of furniture or fabric in the house.
Dog allergies treatment
Removing the offending allergen from the dog's environment is the ideal treatment for dog allergies. When this is not possible, a beneficial response may be achieved with antihistamines. Chlorpheniramine can be administered orally. Glucocorticoids can be used if antihistamines are unsuccessful. If treatment is effective, the dog's allergy signs will generally resolve within a few days. Medication is continued only as long as needed to control the signs.
