Just like us, dogs can suffer from allergies. However, where human allergy symptoms normally include sneezing, wheezing, runny nose and watery eyes, a dog's allergy symptoms are different.

Although canine allergies are not life-threatening, the itching that they cause can make your dog miserable. As a pet owner, we know you want your dog to be as healthy and happy as possible.

Here are a few common questions and answers about canine allergies that should help you better understand the problem, so you can give your pet proper care.

How Many Dogs Suffer From Allergies?

About 1 out of every 5 dogs in the U.S. suffers from some type of allergy.

What Causes Allergies?

An allergy is a disease that is the result of the immune system reacting abnormally to a common substance, such as pollens, molds, house dust, insect bites, foods, and chemicals. The offending substances are called allergens. Inhaling, ingesting or physical contact with the allergens may cause an allergic reaction.

How Will I Know If My Dog Has Allergies?

The most common sign is itchiness and scratching. Usually scratching due to allergies is more intense than normal, and can result in rashes, hair loss and secondary infections. If your dog seems to be scratching more than usual, check the skin for these signs.

What Types Of Allergies Are Commonly Seen In Dogs?

 *  Flea Allergic Dermatitis (FAD): FAD is the most common form of canine allergy. If a dog is allergic to fleas, just one bite can cause itching for up to three weeks. Complete elimination of fleas in the dog's environment is necessary to control Flea Allergic Dermatitis.

* Food Allergies: Foods often cause allergy problems for dogs. The symptoms are usually skin-related, but may include vomiting and diarrhea.

* Atopy: Atopy is the name used for allergies associated with inhaled pollens, molds, house dust and other common airborne substances. This type of allergy is almost always manifested by itchiness and scratching.

How Should Allergies Be Treated?

The best and obvious treatment for canine allergies is avoidance. Flea Allergic Dermatitis and food allergy can be controlled by eliminating the offending food and stringent flea control. It is almost impossible, however, to avoid the common airborne allergens, such as house dust and pollens. By desensitizing your pet to the offending substances, called immunotherapy, the symptoms can be controlled.

What Is Immunotherapy?

Immunotherapy is a process whereby injecting larger and larger amounts of the offending allergens into the dog, the animal's immune system gradually becomes "desensitized" to these allergens. In a large number of dogs, symptoms can be controlled safely and effectively.

Before treatment can begin, however, the allergens causing your dog's reactions must be identified through testing. Then your veterinarian can effectively treat the allergy.

What Should I Do If My Dog Has Allergies?

Consult your veterinarian. Discuss the possibility of having your pet tested and treated. Don't let your dog suffer from canine allergies when a safe and effective treatment is available.

It's up to you to make sure your dog is as healthy and happy as possible.
