Itchy skin, puffy eyes and chewed feet are all symptoms of dog allergies. Dogs have the same susceptibility to allergies that humans do--but not the common sense to stay away from the causes. Often, just removing the source of the allergy is all that is needed to relieve Rover's symptoms.

Flea Allergy
-
Flea allergy is the most common of dog allergies. Flea saliva contains components that include amino acids, phosphorous and polypeptides. When the flea bites your dog, these compounds are deposited beneath the surface of the skin, eliciting an allergic response. You are usually first made aware of the allergic reaction when you notice your dog scratching, biting, licking or chewing parts of his body. Have your house treated by an exterminator to eliminate the flea population. You will also need to ask your veterinarian to place your dog on a flea treatment program.
Inhalant Allergy
-
Pollen, dust, dander, leaves, trees and grass can all produce an allergic reaction in your dog. The response shows up as rashes on the skin, red swollen eyes and a runny nose. Often, you will notice your dog biting at his feet or scratching his ears. Antihistamines are usually effective in treating inhalant allergies. Keep your dog away from the source as much as possible.
Bacteria Allergy
-
Bacteria live on the surface of the dog's skin. If the skin is broken in any way, such as through a cut or scratch, the bacteria can multiply and enter the bloodstream. You may notice your dog repeatedly rubbing his face and body on the carpet or furniture. His skin may become blotchy and smelly. Your veterinarian will determine if your dog needs antibiotics to reduce the chance of infection. Medicated baths can help with the itching.
Contact Allergy
-
This is the least common of dog allergies. It happens as a result of an irritant coming into direct contact with the dog's skin. This happens on the neck area from flea collars. The feet are also entryways to allergens such as fertilizers, bug sprays or even detergents used on the floor. The reaction is an itchy rash at the point of contact. Removing the source of irritation will allow the rash to disappear. Steroid creams can help with the itch as the dog heals. Sometimes, finding the source can be a lengthy process of elimination.
Food Allergy
-
Food allergies are common in dogs. Wheat, corn, eggs, beef, soy and dairy products are the usual suspects. Unfortunately, these foods are also the most common ingredients in dog food. Switching to a food with fewer of these ingredients may be all that is needed to solve the problem. The symptoms usually appear as itchy skin, involving the face, feet, ears and anal area. Food allergies can develop any time from puppyhood to old age.
