Common Causes Of Dog Scratching

By Moses Wright

Dog scratching is a common reason for veterinary visits. There are numerous causes of dog scratching.

One of the most noticeable causes of dog scratching is fleas. Dog owners may see the fleas, see the flea dirt, or even get bitten by fleas themselves.

A flea infestation on a dog and the dog scratching can get so severe that the dog may have hair loss and sores on the skin. Many times this is due to an allergic reaction to flea saliva.

In addition to flea saliva allergies, other types of dog allergies can cause dog scratching. Dogs can develop allergies to dog food, medication, vaccinations, or substances in their environments.

Ear mites can cause dog scratching, especially of the dog's ears. Dogs often shake their heads when they have ear mites.

Mange is a parasitic infection from mites that can cause intense itchiness. Tick bites and infestations of hookworms or lice can be causes of dog scratching.

A common cause of dog scratching are hot spots. Hot spots are a severe, prolonged reaction to a skin injury or irritation from infections, allergic reactions, or poor grooming. Hot spots can also cause hair loss and severe skin irritation.

Staph infections and hypersensitivity to staph can cause intense itchiness. Hair follicles can become infected with staph. A skin condition that is a cause of dog scratching is sebaceous adenitis. Sebaceous adenitis can also cause hair loss.

Two less common causes of itchiness than some of the previous causes are calcinosis cutis and pelodera dermatitis. Often a symptom of Cushing's disease, calcinosis cutis causes mineral buildups of the skin. Pelodera dermatitis is caused by larvae from a worm that is not normally parasitic.

One possible cause of dog scratching is cancer. Cancers that can be causes of dog scratching include lymphoma and epitheliotropic lymphoma.

As in humans, mosquito bites and insect stings can cause itchiness. Bee and wasp stings can cause hives and ulcers. Itchiness is an uncomfortable symptom of many veterinary conditions. Dogs that are scratching frequently should be examined by a veterinarian for proper diagnosis and treatment. - 29895
