Oclacitinib is a pill for dogs that helps control itching and skin inflammation caused by food or environmental allergies.

Atopic dermatitis in cats is a chronic inflammatory skin condition caused by an allergic reaction to substances in the environment.

Hives (urticaria) are an uncommon condition where dome-shaped bumps (wheals) develop on a dog’s skin. Hives are  most commonly caused by reactions to insect bites or allergies. Hives are rarely dangerous, although in severe cases swelling around the throat may impact breathing.

Feline acne occurs when the follicles on the chin become clogged with oils from the skin and dirt from the environment. The causes are not fully understood but have been linked to poor grooming, infection, stress, allergies, or abnormal sebum production.

Canine acne describes an inflammatory skin condition primarily affecting the chin and lips of young dogs. The underlying disease process is not fully understood, but it is thought that injury to the muzzle causes inflammation of the hair follicles which sometimes leads to secondary infection, pain and itchiness.

Eosinophilic granuloma and  furunculosis are skin conditions which manifest in dogs as red or yellow bumpy nodules which can be itchy or painful. They result from skin inflammation triggered by hypersensitive reactions and are associated with insect bites.

Eosinophilic granuloma complex is a condition characterized by the appearance of lesions on the skin in response to an allergen. Eosinophils (a type of white blood cell) target the allergen in the blood, leading to a grouping of inflammatory cells (granuloma) that creates a large mass or lesion on the skin.

Feline asthma is an inflammatory response to respiratory irritants and stress that narrows the airways, making it difficult to breathe. In cats, the cause appears to be an allergic reaction to environmental irritants that causes hypersensitivity of the airways.

Cats experience two types of contact dermatitis: allergic and irritant. They both involve skin contact with an offending substance which leads to a dermatologic reaction.

Allergies are common in cats, similar to other species. Harmless proteins in the environment (allergens) stimulate the immune system, which overreacts and produces a strong inflammatory response.

Food allergies occur when the immune system overreacts to an ingested protein.

Food allergies are a reaction of the immune system to specific proteins within the diet.

Whereas humans get sneezy and sniffly at certain times of the year, some cats get red, itchy skin and secondary skin infections for the same reason: seasonal allergies.

Canine allergies are common and occur when the immune system overreacts to allergens the dog is exposed to.

Contact dermatitis refers to inflammation of the skin in response to an allergen or irritant making physical contact with a dog’s skin cells.

Atopic dermatitis (or atopy) is a common allergic condition in dogs that is similar to human environmental allergies (hayfever). Determining what the dog is allergic to is rarely necessary for management of the disease, but examples of common dog allergens include pollen, dust mites, and mold spores. 

Flea allergy dermatitis (FAD) is a skin disease that results when a cat develops an allergy to flea saliva. The body treats the allergen as a harmful substance and reacts disproportionately.

A flea allergy, or flea allergy dermatitis, is an inflammatory response to flea bites,
