Some pets are not allergic to food but to substances in their environment. When inhalant allergens are suspected, this type of skin problem is called atopy. Like humans, dogs and cats can be allergic to pollen, mold spores, dust, or other allergens that can appear in the outside environment or even in the house, that they breathe in or absorb through the skin. The bite of certain insects, such as mosquitoes and gnats, can also cause an allergic reaction. The symptoms are typically seasonal in nature, and tend to worsen as the pet ages. While people tend to sneeze when they are allergic, animals tend to itch. Once recognized, the symptoms generally can be controlled although not totally eliminated. Allergy testing through the use of an intradermal skin test can help determine what the pet is allergic to. Management and treatment consists of removing the allergen from the pet's environment or preventing exposure to it if possible and treating the pet with topical and systemic therapies and medications. Allergy shots (immunotherapy) can also be helpful for some atopic dogs.
 

Flea infestations are a common cause of itching and scratching in pets. Some pets are so allergic to fleas, that even just a bite or two will cause a severe reaction leading to itching, scratching, lesions, crusting, and hair loss. FAD is particularly difficult to diagnose in cats because of their fastidious grooming efforts: they may groom fleas and any signs of fleas completely away. In addition, because cats tend to groom themselves frequently anyway, it can be hard for owners to tell the difference between normal
and excessive grooming. If a pet has a suspected reaction to fleas, aggressive steps must be taken to eliminate fleas on the pet, in its environment, and from any other pets in the household.
 

Dogs and cats of any age can develop food allergies. Specifically, ingredients in some pet foods can cause an allergic reaction in sensitive dogs and cats. Symptoms can include itching, ear infections, and gastrointestinal upsets. The problems are usually related to a protein or carbohydrate in the diet. Pets with food allergies tend to itch all year long instead of seasonally. What can complicate diagnosis of a food allergy is that many of these pets also may have concurrent allergies to fleas or other allergens in their environments.

When a food allergy is suspected, the veterinary dermatologist will recommend that you put your pet on something called a 'food elimination diet' that will help determine which food item your pet is reacting to. This is a complex process that takes place over a period of several months. Your pet is first fed a hypoallergenic diet, which is a prescription diet available only through a veterinarian, until symptoms disappear. Then, your pet is 'challenged' by feeding it different special diets that can help determine which food item your pet is reacting to. Once the allergen (s) is identified, it can be eliminated from your pet's diet, hopefully ending the allergic reaction that is making your pet itch and scratch. Note: While on a food elimination diet, it is very important not to feed your pet anything other than the elimination diet and treats and medications that are expressly approved by your veterinary dermatologist.
 

This is really just a fancy name for an ear infection, specifically the external ear canal. If the middle or inner ear canal is infected, it's called otitis media or otitis interna. Ear infections can run the gamut from a mild infection due to a temporary situation, such as a dog getting water in its ears during a swim and developing inflammation, to a more serious, chronic infection that can be difficult to treat. Ear infections can be caused by allergies, ear mites, water in the ears, systemic disease, allergies, or any number of things. Dogs with flopped ears are also more prone to ear infections. Cats are less prone to ear canal infections than dogs but they do get them. Infected ears are usually red, sensitive to the touch, and may exude an odorous fluid. Serious, chronic cases may require surgical correction. Severe ear infections can lead to partial deafness, imbalance, and vomiting.
