Most dogs suffer from skin allergies (also known as allergic dermatitis). Dog skin allergies typically stem from one of three sources:
● An itchy rash brought on by a flea allergy
● Anaphylaxis to food
● Pollen, dust mites, and other environmental allergens
Dermatitis caused by flea bites is an allergic reaction. Some canines are susceptible to flea saliva. Affected dogs' skin may become red,inflamed, and scabbed, and they may experience extreme itching, especially at the base of the tail. Seeing fleas or flea dirt is another possible indication that you have a flea problem.
Skin rash is another symptom of food allergies and sensitivities. In addition, dogs with food allergies often experience itching in the ears and paws and possible gastrointestinal symptoms.
Environmental allergens like dust, pollen, and mold can trigger atopic reactions and dermatitis. Dogs with these types of allergies typically only show symptoms during specific times of the year. Paws and ears are the most typical target areas, just like human food allergies (including the wrists, ankles, muzzle, underarms, groin, around the eyes, and between the toes).
Secondary infections can occur with any skin allergy. For example, your dog may develop yeast and bacterial infections on his skin if he constantly licks, bites, and scratches at it.
