If your dog’s fur chewing is the result of itchy skin, there are several possible reasons.

Allergies

Allergies in dogs are common and usually manifest within the first six months of age to five years old and can affect any breed or sex of the dog. Atopic dermatitis, which is an allergic reaction affecting the skin is more common in Chinese Shar-Peis, Wirehaired Fox Terriers, Golden Retrievers, Dalmatians, Boxers, Boston Terriers, Labrador Retrievers, Lhasa Apsos, Scottish Terriers, Shih Tzus, and West Highland White Terriers. Atopic dermatitis may lead your dog to chew off his fur to satisfy an itch that won’t go away. Skin may be pink and warm.

Skin Disorders

Seborrheic dermatitis is one possible skin issue. Your dog’s sebaceous glands, which are just below the surface of the skin may overproduce sebum, an oily or waxy substance that is used to waterproof and protect the skin. When this occurs, your dog’s skin will flake off in scales or possibly look red and inflamed. Seborrheic dermatitis will also cause your dog’s skin to become itchy, and he will scratch and chew at his fur to relieve himself. Usually, a foul odor is also associated with this type of skin disorder.

Infections

An open wound or scratch, if left untreated, can quickly develop into an infection. Additionally, untreated allergies or skin disorders can cause your dog to scratch and chew his fur off, which may then lead to a secondary infection. Yeast or bacteria can cause secondary infections. Malassezia overgrowth is a common yeast infection that affects dogs that chronically chew at their fur. Your dog’s mouth and the environment may also trigger a bacterial infection, especially if your dog has self-mutilated his skin through chewing off his fur.

Insect and Parasite Bites

Insect bites from fleas, ticks, flies, or mosquitos can cause your dog to chew at his fur at the site of the bite leading to an inflamed area known as a “hot spot.” Hot spots are acute moist dermatitis and can become large red lesions very quickly. Hot spots develop by disturbing the natural bacteria on your dog’s skin and causing it to overgrow through scratching or chewing on the skin at the site of the insect bite. Bacterial overgrowth will further exacerbate the area, and your dog will chew harder trying to satisfy his itch.

Stress and Anxiety

Stress from change or separation anxiety can adversely affect your dog and he may self-mutilate by chewing his fur off. Dogs require companionship and stimulation. If your dog is starting to chew on his fur and no underlying medical condition is apparent, he may be lonely or bored. Other destructive behaviors may accompany separation anxiety or stress, such as incessant barking, destroying furniture, or scratching at doors and walls.
