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 will 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
