What Are The Causes Of Dog Scratching?
Several veterinary resources state that dog scratching is one of the most common reasons for veterinary visits. Several parasite infestations and skin conditions are causes of dog scratching.
While most causes of dog scratching are difficult to identify, fleas are often noticeable. The fleas or the flea dirt may be visible or the dog owner may be bitten by the fleas themselves.
A severe flea infestation can cause hair loss and sores on the dog’s skin due to scratching. Dogs may be allergic to flea saliva that can make these symptoms significantly worse.
Other types of allergies can also cause skin irritation that leads to scratching. Dogs can be allergic to materials or substances in their environments, vaccinations, medications, or the food they eat.
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 infestation that can be a cause of intense dog scratching. Causes of dog scratching from parasites can also be due to lice, ticks, and hookworms.
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.
Itchiness in dogs can be caused by infection of hair follicles by staph or hypersensitivity to staph. Sebaceous adenitis is a skin condition that causes destruction of the sebaceous glands. Sebaceous adenitis causes dog scratching and 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.
Some types of cancer can cause itchiness in dogs. Lymphoma and epitheliotropic lymphoma are two types of cancer that can be causes of dog scratching.
Mosquito bites and stings from bees or wasps can cause itchiness. In severe reactions to insect stings, ulcers or hives may develop. Since itchiness is a uncomfortable symptom of many different conditions, dog owners should have their dogs examined by a veterinarian for diagnosis and treatment.
