Reasons Why Dogs Bite Themselves
Biting and itching are symptomatic of several possible dog problems. Constant biting can lead to irritations, resulting in swollen and damaged skin, bacterial infections and hot spots. Diagnosing the cause of biting can reduce the risk of complications for your dog

Medical Conditions
-
Dogs commonly bite themselves to relieve the pain of another area. Hyperthyroidism or orthopedic conditions--hip displaysia, broken ligaments, or bone and joint problems--may arise due to age or breed. These conditions can lead to a dog biting, licking and itching its feet. Veterinarians can diagnose the source of pain through blood work, X-rays and observations.
Insects
-
Fleas, ticks, chiggers and other insects can cause irritation to a dog's skin, resulting in frequent gnawing or itching to sooth the area or remove the foreign object. Sprays, shampoos, preventative treatments and veterinarian-prescribed products can heal and defend against infestations.
-
Allergies
-
Dogs are susceptible to food and environmental allergies that can cause uncomfortable rashes, stomach sensitivity and itchy skin. Veterinarians can prescribe steroids and antihistamines to prevent further inflammation from reactive biting, and can recommend hypoallergenic foods.
Fear and Boredom
-
Dogs suffering from separation anxiety, fear, neglect or lack of exercise may chew themselves as a way of calming their nerves or occupying their time alone. Daily exercise, training and chew toys can help correct this behavior.
Dermatitis
-
A dog's skin can be irritated by foreign materials, grass, humidity or ingested objects, weakening the immune system. This allows parasites, bacteria and yeast to attack, causing infectious dermatitis, which leads to discomfort, resulting in biting or licking. Antihistamines, antibiotics, topical treatments and cortisone can be prescribed to relieve symptoms and cure the affected area.
