By the end, you’ll feel better equipped to recognize concerns early and to work with your veterinarian on a plan that keeps your canine friend as comfortable as possible.

Why Cancer Happens in Dogs

Cancer is the uncontrolled growth of abnormal cells. Just like in people, cancer in dogs can develop almost anywhere in the body. Some breeds are predisposed to certain cancers, while age and environmental factors also play a role. Dogs are living longer thanks to improved preventive care, which means we see cancer more often simply because more pups are reaching their senior years.

Our Suwannee County veterinarians stress that cancer isn’t always a “death sentence.” Many types are treatable, and some are even curable with the right combination of surgery, medication, and supportive care.

Common Types of Cancer in Dogs

Lymphoma

One of the most common canine cancers, lymphoma affects the lymphatic system. Dogs often present with swollen lymph nodes under the jaw, in front of the shoulders, or behind the knees.

Mast Cell Tumors

Skin tumors that may look like small lumps but can vary in appearance. Some are benign, but others can spread aggressively.

Osteosarcoma

A bone cancer seen more often in large breeds. It often develops in the limbs and can cause sudden lameness or swelling.

Hemangiosarcoma

A cancer of blood vessels, often affecting the spleen or heart. It’s known for developing silently before causing sudden illness.

Mammary Gland Tumors

More common in unspayed females. Spaying before the first or second heat cycle dramatically reduces risk.

Melanoma

Not just a skin tumor—it can also occur in the mouth, often appearing as dark masses on the gums or tongue.

The National Canine Foundation has a series of articles on canine cancer, which you can read here. PetMD also has a blog on cancer in dogs, which you can read here.

Early Signs of Cancer in Dogs

Because cancer can mimic other conditions, families should stay alert for subtle changes. Our veterinary clinic in Suwannee County encourages you to call if you see:

• New lumps or bumps that grow or change
  
• Unexplained weight loss or loss of appetite
  
• Lethargy or reduced interest in play
  
• Persistent limping or stiffness
  
• Wounds that don’t heal
  
• Changes in bathroom habits
  
• Difficulty breathing or coughing
  
• Swelling of the belly
  

Early detection gives our veterinarians more treatment options and improves outcomes. If you brush your dog’s teeth, pay attention to his mouth and gums while you do. (Click here for our blog on doggy dental woes.)

Diagnosing Cancer at Our Animal Hospital

If we suspect cancer, our Suwannee County vets will recommend diagnostic tests such as:

• Fine needle aspiration (collecting cells from a lump)
  
• Biopsy (removing tissue for lab evaluation)
  
• X-rays or ultrasound to check for spread
  
• Bloodwork to evaluate organ function
  
• Advanced imaging like CT or MRI (when needed)
  

Diagnosis allows us to identify the cancer type, stage, and best treatment options for your furry bestie.

Treatment Options for Canine Cancer

Surgery

Many cancers are best treated by removing the tumor. Surgery may be curative if the cancer hasn’t spread.

Chemotherapy

Dogs tolerate chemotherapy better than humans. Most experience minimal side effects, and the goal is comfort as well as tumor control.

Radiation Therapy

Used for tumors that can’t be fully removed surgically or for certain types of cancer like nasal tumors.

Immunotherapy

An emerging treatment that uses the dog’s own immune system to fight cancer.

Supportive Care

Even when cure isn’t possible, supportive care focuses on keeping dogs comfortable through pain management, nutritional support, and regular monitoring.

Caring for a Dog with Cancer at Home

At our veterinary clinic, we remind families that dogs live in the moment. With care and adjustments, many dogs with cancer still enjoy daily walks, belly rubs, and play. Supportive steps include:

• Keeping routines consistent to reduce stress
  
• Offering easily digestible, nutritious meals
  
• Monitoring for changes in energy, appetite, or comfort
  
• Providing soft bedding and a quiet rest area
  
• Regularly checking any lumps or surgical sites
  

Fun and Helpful Facts About Cancer in Dogs

• Roughly 1 in 4 dogs will develop cancer in their lifetime.
  
• Golden retrievers and boxers are among breeds with higher cancer risk.
  
• Dogs rarely lose their fur completely during chemotherapy—side effects are generally milder than in humans.
  
• Spaying females before their first heat cycle nearly eliminates the risk of mammary cancer.
  

FAQ: Dog Cancer

Is every lump cancer?

No. Many lumps are benign (like lipomas), but only a veterinarian can tell for sure with testing.

Does cancer always mean a poor quality of life?

Not necessarily. Many dogs live comfortably for months or years with the right treatment and monitoring.

How expensive is treatment?

Costs vary widely. While we won’t discuss prices here, we will work with you to design a plan that fits your family and your dog’s needs.

Can diet prevent cancer?

No diet can guarantee prevention, but maintaining a healthy weight, balanced nutrition, and regular checkups reduce overall risk.
