Dogs have allergies, just like people. Dogs can be allergic to food, inhalants, substances they touch and more. Most dogs exhibit symptoms of allergies through their skin instead of as a respiratory condition.

Inhalant Allergies
-
Inhalant allergies occur when a dog inhales airborne allergens that circulate in the air the dog breathes. This can include pollen, mold spores, dust, smoke and any other pollutant.
Food Allergies
-
Food allergies manifest if the dog ingests food containing ingredients that that its body can't tolerate. Food allergies are normally caused by the nonprotein ingredients in dog food, such as corn and wheat.
Contact Allergies
-
Contact allergies occur when a dog comes into physical contact with an irritant. The symptoms are normally localized to the area making the contact. It's easily treated by removing the offending allergen.
Flea Allergies
-
Flea allergies occur when dogs are repeatedly bitten by fleas. Many dogs are allergic to a protein component of the flea's saliva, which causes severe itching. Dogs with this allergy will exhibit their sensitivity by constantly scratching the affected area.
Treatments
-
Treatments include removing as much of the allergen as possible from the dog's environment, prescribing antihistamines and potentially periodic steroid use.
