When it comes to your dog’s health, you might not give skin cancer much thought. However, despite their fur shielding them from the sun, dogs can develop skin cancers and tumors. Luckily, most cases can be treated when caught early. The pet dermatologists from Veterinary Dermatology Services in Cincinnati, OH, want to help you better understand this condition.

What Are the Causes of Dog Skin Cancer?

pet dermatologistsSun exposure is one of the causes of skin cancer in dogs. Typical spots where it can develop include the nose and ears since these areas have little protection from the sun. Dogs with thin coats or light-colored fur are more susceptible to developing sun-related skin cancer. Other causes include hormonal dysfunction in older dogs and genetic predisposition.

What Are the Types of Dog Skin Cancer?

There are three main types of dog skin cancer: malignant melanoma, squamous cell carcinoma, and mast cell tumors.

Malignant melanoma

Malignant melanoma is skin cancer that affects pigmented skin cells called melanocytes. When dogs develop malignant melanoma, it’s usually on the mucous membranes or the mouth. They can grow rapidly, spreading to the internal organs such as the lungs and liver. It’s unclear exactly why melanomas develop, but genetic predisposition is seen as a key factor. Malignant melanoma is usually treated with surgery, but in cases where surgery is not possible, radiation can be used.

Squamous Cell Carcinoma

Squamous cell carcinoma in dogs is usually caused by sun exposure, but some pet dermatologists believe there might be a link with the papilloma virus. While squamous cell carcinoma cancer does not attack the lymph nodes, it can destroy the tissue surrounding the tumor. This cancer results in firm, wart-like tumors, usually occurring on the genitals or abdomen. A specialist can treat this type of cancer surgically, without the need for chemotherapy or radiation.

Mast Cell Tumors

These are the most common kinds of dog skin cancer, and they develop in the immune system’s mast cells. While the cause isn’t certain, pet dermatologists believe that mast cell tumors are caused by genetic predisposition and hormone levels. Most mast cells tumors are rubbery in texture and appearance, but more aggressive forms can ulcerate on your dog’s body. A pet dermatology specialist will typically treat these kinds of cancers surgically, while more resistant cases will require radiation and chemotherapy.
