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
Itchy, runny eyes
Itchy back or base of tail (most commonly flea allergy)
Itchy ears and ear infections
Snoring caused by an inflamed throat
Paw chewing/swollen paws
Allergic dogs may also suffer from secondary bacterial or yeast skin infections, which may cause hair loss, scabs or crusts on the skin.
If you believe you dog might have allergies, visit your veterinarian. After taking a complete history and conducting a physical examination, he or she may be able to determine the source of your dog’s allergic reaction. If not, your vet will most probably recommend skin or blood tests, or a special elimination diet, to find out what’s causing the allergic reaction.
