You may be a little puzzled when your dog suddenly is obsessed with his paws. He chews and licks them constantly. You look closely but cannot find any sores or splinters that can explain his behavior. Surprisingly, the answer to all of this licking and chewing may be allergies. Regardless if they’re caused by food, flees or environmental factors such as pollen,  canine allergies can manifest themselves in your dogs skin which causes itching and discomfort. After your regular veterinarian exams your dog, a veterinary dermotologist can test for allergies. Treatment may involve changing foods, administering antihistimines, or giving you dog a medicated bath. So dog toys, rawhide bones and dad’s socks aren’t the only things that a dog can chew.
