While our canine friends are covered in fur, skin cancer is still a very real health issue. Today, our veterinarians list three types of skin cancer we often see in dogs. 

Lumps & Bumps on Your Dog

You may be worried about cancer if you've discovered a discolored patch of skin or a lump on your furry companion. that said, it's important for pet parents to keep in mind that not all lumps or bumps are cancerous. For those that do prove to be cancerous, there may be treatments if these abnormalities are detected early. 

If you've found something suspicious on your dog, contact your vet to schedule an examination for your pet. The success of treatment may depend in large part on the earliest possible detection. 

Types of Skin Cancer in Dogs

Squamous Cell Carcinoma

The most commonly diagnosed type of skin cancer in dogs typically impacts older animals and is often seen in Beagles, White Bull Terriers, Whippets and Dalmations. Squamous cell carcinoma appear as raised wart-like patches or lumps that feel firm to the touch. They are often found on a dog's head, lower legs, abdomen and rear. Sun exposure may be a cause of squamous cell carcinoma. However, there may be a link to papillomavirus.

Malignant Melanoma

Frequently found around a dog's mouth, lips and nail bed, melanomas are raised bumps that may be dark in pigment (but not always). While most melanomas are benign, they can be malignant, which is when they become a very serious threat to your pup's health. These quickly growing tumors have a high risk of spreading to other organs. Scottish Terriers and Schnauzers appear to face an increased risk of developing melanoma, and male dogs more at risk than females. 

Mast Cell Tumors

Mast cell tumors occur in the mast cells of the immune system and are very common in dogs. These tumors can grow anywhere on the skin, and even on the dog's internal organs. That said, some of the most common sites for mast cell tumors to appear are on the limbs, lower abdomen and chest. This form of skin cancer can occur in any breed but is most often seen in Boxers, Pugs, Rhodesian Ridgebacks, and Boston Terriers between ages 8 -10 years old.

Diagnosing Dog Skin Cancers

To diagnose skin cancer in dogs, your vet may perform a fine needle aspiration in order to take a small sample of the tumor's cells to examine or perform a biopsy in order to take a portion of the tumor's tissue for examination. These samples will be analyzed at a lab in order for your veterinarian to provide you with an accurate diagnosis of your pup's condition. 

In order to determine the extent of your dog's cancer additional diagnostic testing may be recommended. This can help to optimize treatment and give a more accurate prognosis for your pet.

Treatment for Skin Cancer in Dogs

Many early-stage dog skin cancers can be treated successfully, allowing pets to continue living comfortable, happy lives for months or years to come.

Your dog's skin cancer treatment could include surgery, chemotherapy, immunotherapy, targeted therapies or palliative care when appropriate. When it comes to the prognosis and treatment for skin cancer in dogs, options will depend on a number of factors, such as the type of tumor, the tumor's location and how advanced your dog's cancer is.

Monitoring Your Pet's Health

Spotting the signs of skin cancer while the disease is still in the early stages is the key to good treatment outcomes. During your regular grooming routine, familiarize yourself with all your dog’s normal lumps, bumps and rashes so that you can spot changes in your pup's skin right away.

Visiting your veterinarian for routine wellness exams, even when your dog appears perfectly healthy, can help to catch skin cancers in the early stages.

Whenever you notice an unexplained or unusual lump or bump on your dog, or if you notice swelling around your dog's toes, consult your vet right away. When it comes to your pet's health, it's always better to err on the side of caution.
