Allergic reactions in dogs are hard to control and are usually chronic in nature. This is why the right diagnosis and therapy has to be started early to minimize the allergic reaction. The most common symptom for allergic reaction in dogs is excessive itching, or pruritis. It is the high strung dogs that tend to itch more than placid dogs while chewing, licking and rubbing of the skin are all manifestations of pruritis.

The common areas on the dog’s body that are the hardest hit for pruritis are its face, feet and armpit. However, due to some extent of excessive pruritis, it might cover the whole body of the animal. Scratching is normal for them and sometimes not a sign of any irregularities on their skin. But when tiny blood spots appear, it’s already a sign of an allergic reaction. The reason for this is, flea dirt comprises more of blood and they usually appear as small blood spots in any place that they are left behind.

There are basically three types of allergic reactions in dogs where the dog may suffer from one of these reactions or a combination of all three conditions. The dog may have a food allergy where it is allergic to ingredients or preservatives found in food. The most common food allergens for dogs are beef, wheat, dairy products, lamb and poultry products. Even premium dog foods tend to contain these products.

Usually, dog owners visit a pet store with good reputation to look for there dogs in order to stop allergic reactions. At this point, store employees usually recommend some dog food to stop the itching thinking that this is the main cause for allergic reactions in dogs. Besides, food allergies are basically the least common of allergic problems found in diagnosed skin problems.

With flea allergy dermatitis, it is the allergens found in the saliva of flea that bites the dog. The flea inserts a coagulant in the dog through the saliva to prevent the clotting of the dog’s blood, and this is what induces an allergic reaction in dogs.

In this the main stimulants for allergic reactions in dogs is when flea inserts a coagulant through the saliva to prevent the clotting of the dog’s blood. However the occurrences of new and effective treatments have now diminished.

The last type of allergic reactions found in dogs is what they call allergic inhaled dermatitis or atopy, a pre-inclination in the animal to produce IgE antibodies on exposure to an allergen.

The common allergens here are pollen, house dust, feathers, grasses, animal dander, mold and mites which are either ingested by the dog or passed through the pads of its feet.
