Answer
Hi Monica,

Paw-licking and chewing are common signs of disease in dogs.

The most common cause for the itch you describe is atopic dermatitis, or inhalant allergy. This is similar to hay fever in humans except that the result is usually foot-chewing rather than the respiratory signs that humans suffer. Allergens include dust and dust mites; pollens from trees, weeds, grasses and other plants; molds; mildew; animal or human dander, including wool; and insects. Usually more than one substance is involved.

Foot chewing can lead secondary infections (bacteria and yeast like warm moist skin), which leads to deeper penetration of the organisms into the tissues, creating a very itchy cycle that is hard to break.

The cause of the itch has to be established. If you address only the itchy symptoms this problem may never be cured. It is important to establish a specific diagnosis and rule out complicating factors to properly address foot-chewing in dogs. Your dog should be examined by your vet.

Allergies can be difficult to treat in dogs. It may require trying several different medications to find the best drug or combination of drugs work best for your dog. So whatever your vet ends up prescribing, if you don't see improvement, or if the itching seems to subside but then returns, you'll know you need to get in contact with your vet.

Best of luck,
Patti
