How common is cancer in dogs?

Cancer statistics in dogs

Cancer is a prevalent disease in dogs, with statistics showing that it affects a significant number of our furry friends. According to studies, about one in three dogs will develop cancer in their lifetime.

This means that it is a widespread health concern that dog owners should be aware of and prepared to address. The risk of developing cancer increases as dogs age.

Dogs over the age of 10 are particularly prone to various types of cancers. As our canine companions enter their senior years, it becomes even more crucial to monitor their health closely and be vigilant for any signs or symptoms that could indicate the presence of cancer.

Increased risk for dogs that are not spayed or neutered

Apart from age, certain factors can increase a dog’s risk of developing cancer. One such factor is whether a dog has been spayed or neutered.

Studies have shown that intact (non-spayed or non-neutered) dogs are more susceptible to certain types of cancers, such as mammary tumors and testicular cancer. Spaying or neutering your dog at an early age can significantly reduce their risk of developing these types of cancers.

It is important to consult with your veterinarian to determine the best timing for spaying or neutering your dog based on their breed, size, and overall health.

Types of cancer in dogs and their symptoms

Lymphoma in dogs

Lymphoma is a common type of cancer in dogs that affects their lymphatic system. This system plays a vital role in the body’s immune response.

The symptoms of lymphoma can vary depending on the affected organs, but common signs include swollen lymph nodes, weight loss, lack of appetite, lethargy, and increased thirst.

Osteosarcoma in dogs

Osteosarcoma is a type of bone cancer that is most commonly found in large and giant dog breeds. The symptoms of osteosarcoma can include lameness or limping, swelling or lumps around the affected bone, pain, and decreased activity levels.

Mast Cell Tumors in dogs

Mast cell tumors are a form of skin cancer that can affect dogs of any age or breed. These tumors can vary in appearance, ranging from small, raised nodules to larger masses.

Symptoms may include itching, redness, ulcers, hair loss, and in some cases, systemic symptoms such as vomiting and diarrhea.

Mammary Tumors in dogs

Mammary tumors are most commonly found in female dogs, particularly those that have not been spayed. These tumors can be benign or malignant, and they often manifest as lumps in the mammary glands.

Symptoms to watch out for include swelling, pain, discharge from the nipples, and changes in the size or shape of the mammary glands.

Hemangiosarcoma in dogs

Hemangiosarcoma is a highly aggressive cancer that affects the blood vessels in dogs. It commonly occurs in the spleen, liver, or heart, and symptoms can include weakness, pale gums, abdominal distension, and collapse.

Unfortunately, by the time symptoms become noticeable, the cancer is often in an advanced stage.

Soft Tissue Sarcomas in dogs

Soft tissue sarcomas can develop in various areas of a dog’s body, such as the connective tissues, muscles, or fat. Symptoms of these tumors can include lumps or bumps that can be felt under the skin, as well as pain or discomfort in the affected area.


Cancer is a significant health concern for dogs, with one in three dogs being affected by this disease in their lifetime. The risk of developing cancer increases with age, and intact dogs are at a higher risk for certain types of cancers.

Recognizing the symptoms and seeking veterinary care promptly are essential for early detection and treatment. A better understanding of the different types of cancers that can affect dogs and their associated symptoms can help owners be proactive in ensuring their beloved pets receive the necessary care and support.

What to do if you suspect your dog has cancer

Seeking veterinary assessment

If you suspect that your dog may have cancer, it is crucial to seek veterinary assessment as soon as possible. Time is of the essence when it comes to cancer treatment, and the earlier the diagnosis, the better the chances of successful treatment and management.

The first step is to schedule an appointment with your veterinarian. During the appointment, be prepared to provide detailed information about the symptoms your dog is experiencing, including when they started, how they have progressed, and any changes in your dog’s behavior or appetite.

This information will help guide your veterinarian’s assessment and aid in the diagnostic process. Your veterinarian will conduct a thorough physical examination of your dog, paying close attention to any lumps or abnormalities.

They may also ask you questions about your dog’s medical history, diet, and lifestyle. Based on the physical examination and the information you provide, your veterinarian will determine the next steps, which may include diagnostic testing.

Diagnostic testing for cancer

Diagnostic testing is essential for confirming a cancer diagnosis and understanding the type and extent of the disease. Your veterinarian may recommend one or more of the following tests:


Blood tests: Blood work can provide valuable information about your dog’s overall health and may indicate the presence of certain types of cancers. Abnormalities in blood cell counts or liver and kidney function can be indicators of cancer.

2. Radiographs (X-rays): X-rays can help identify the presence of tumors or abnormalities in organs or bones.

They can also provide information about the spread of cancer to other parts of the body. 3.

Ultrasound: Ultrasound imaging can provide detailed images of internal organs and help detect tumors or abnormalities. It is particularly useful for evaluating areas such as the abdomen or heart.

4. Tissue biopsies: A tissue biopsy involves the removal of a small sample of abnormal tissue for examination under a microscope.

This procedure is often necessary to confirm a cancer diagnosis and determine the type and grade of the tumor. In some cases, your veterinarian may refer you to a veterinary oncologist, who specializes in diagnosing and treating cancer in animals.

Oncologists have access to advanced diagnostic tools and expertise in interpreting test results, which can be invaluable in formulating a treatment plan. It is important to remember that not all lumps or abnormalities are cancerous.

Some may be benign, while others may be non-cancerous growths or infections. Diagnostic testing is crucial for accurate diagnosis and appropriate treatment.


If you suspect that your dog may have cancer, seeking veterinary assessment is the first and most important step. Your veterinarian will conduct a thorough examination and may recommend diagnostic tests such as blood work, radiographs, ultrasounds, or tissue biopsies to confirm the diagnosis.

Remember to stay proactive and attentive to your dog’s health, as early detection and treatment are key to improving outcomes for dogs with cancer. Trust in your veterinarian’s expertise and guidance throughout the process.

Cancer and common health complications in dogs are significant concerns that require our attention and proactive care. Recognizing the symptoms of dog cancers, such as unexplained weight loss and lumps, and being aware of common health issues like GI upset or respiratory problems can make a vital difference in our dogs’ well-being.

It is crucial to seek veterinary assessment promptly if we suspect cancer and to be prepared for diagnostic testing, including bloodwork, radiographs, and biopsies. Early detection and treatment are key to enhancing outcomes for our furry companions.

By staying vigilant and working closely with our veterinarians, we can ensure the best possible care for our dogs and their long, happy lives by our side.
