Pet allergies, and especially dog skin allergies, are very common. Food, carpeting, blankets, dust mites, mold spores in the air, pollen, plastic food dishes, furniture stuffing and ornamental plants all have the potential to trigger allergies in dogs.
In some instances, a highly allergic pet may have several allergies at once. The severity of allergies, which can be seasonal or year round, varies greatly.
The most common symptom from an allergy is intense itching (known as pruritus), which may be localized at spots or might be systemic, covering the pet's entire body.
Regardless of what causes the problem, this condition is common, it can last a lifetime, it is a challenge to diagnose, and once identified it can be resistant to attempts at treatment. Dogs with inhalant dermatitis will lick and chew at their paws and scratch their face, eyelids and ears. Others may erupt in hot spots or their skin may redden and be intensely itchy all over.
