What Can I Do if My Pitbull Is Gnawing at His Skin?

Dogs lack the complex understanding of physiology that humans use to refrain from scratching or rubbing at sores or irritations. Without this, dogs are compelled to gnaw or lick at their skin for a variety of reasons. This habit can cause serious problems and injuries if left untreated, and will be indicated by patches of red or swollen skin where no actual wound is evident, bare patches where the fur has been chewed off or feet that have become swollen due to constant irritation.

  1. Check for Irritations

    • If your pitbull's gnawing is concentrated on a specific area of his body, check for sores or scratches. He may also pick up burrs while walking, which can cause irritation which results in gnawing. Several types of skin infections may also compel your dog to gnaw at his skin, and these may need a veterinarian's attention to diagnose. He may chew due to a ringworm infection, which will manifest itself via scaly patches, inflammation and hair loss. Fleas are also a common cause of biting and scratching, and should be treated with medication from your vet. Do not simply buy a flea collar at the pet store or supermarket without consulting your vet, as these may be ineffective or even harmful to your dog.

    Allergies

    • Like humans, dogs can suffer from seasonal allergies such as pollen, mites, dust and certain plants. While these may typically cause congestion and other breathing problems, physical contact with allergens may also irritate your pitbull's skin, causing him to gnaw or lick. Itchy skin can also result from food allergies. It is not uncommon for a dog to be allergic to common foods such as chicken, beef, wheat, soy or corn, all of which are used as ingredients in dog food. A food allergy may also result in diarrhea or vomiting, so consider your dog's food if these symptoms occur without an apparent explanation. Try changing your dog food brand or flavor, paying attention to the ingredients when you change to a new food, and observe your dog's skin and behavior for signs that his gnawing has abated.

    Anxiety

    • Dogs cope with anxiety in many ways, and chewing is a common outlet for dogs when they are stressed or under-stimulated. A bored, lonely or frightened dog may lick or gnaw at his legs compulsively. You can overcome this behavior by showing your dog more attention and affection when you are home, and by giving him toys to play with and chew when he is alone.

    Congenital Disorders

    • The comparatively smaller breeding pools of pure breeds leave many breeds of dog affected by neurological or behavioral disorders, and pitbulls are known for compulsive tail-chasing tendencies for this very reason. Compulsive licking or gnawing at the skin may also be a result of a neurological problem, and can be difficult to cure. Metabolic and hormonal imbalances may also cause irritations within your dog's skin, resulting in changes to his skin color and his coat. If you have ruled out all other possible causes and your pitbull continues to gnaw at his skin, consult your veterinarian about a possible congenital cause and its appropriate treatment.
