Cancer is, unfortunately, one of the most common health concerns facing dogs, especially as they reach their senior years.
While a diagnosis can feel overwhelming, understanding the early warning signs and available care options can make a life-changing difference.
Our team at Maple Grove Pet Hospital is dedicated to helping pet owners navigate these challenges with compassion, advanced diagnostics, and personalized treatment plans.
Early detection is key. If you notice changes in your dog’s health or behavior, scheduling a wellness exam could be the first step toward giving them the best possible outcome.
What Causes Cancer in Dogs?
Cancer develops when abnormal cells grow uncontrollably in the body.
While the exact cause is not always clear, certain risk factors may play a role, including:
- Genetics: Some breeds are predisposed to certain cancers
- Age: Senior dogs are more likely to develop cancer
- Environmental exposures: Secondhand smoke or harmful chemicals can lead to cancer
Even though many causes can’t be controlled, regular veterinary care and preventive wellness exams can help catch problems early.
Signs of Cancer in Dogs
The symptoms of cancer in dogs vary widely depending on the type and location of the disease.
Being alert to early changes in your dog’s body or behavior is one of the best ways to protect their health.
General Signs of Cancer in Dogs
- Lumps or bumps that don’t go away
- Unexplained weight loss or reduced appetite
- Lethargy, weakness, or depression
- Persistent cough or difficulty breathing
- Non-healing wounds or sores
First Signs of Cancer in Dogs
In many cases, the first signs are subtle. You may notice:
- Small lumps under the skin
- Mild limping or stiffness
- Minor changes in appetite or energy levels
Even small changes should be evaluated by a veterinarian to rule out severe conditions.
Types of Cancer in Dogs
There are several types of cancer commonly seen in dogs. The symptoms, treatment options, and prognosis depend on the specific type.
Our team can suggest the best option for your pet.
Skin Cancer in Dogs
Skin cancer often appears as new or changing lumps, sores, or wart-like growths. Mast cell tumors are one of the most common forms of skin cancer in dogs.
Bone Cancer in Dogs
Osteosarcoma, a cancer of the bones, is more common in large breeds. Signs often include limping, swelling, and pain in the legs.
Liver Cancer in Dogs
Liver tumors may cause weight loss, reduced appetite, vomiting, or abdominal swelling.
Bloodwork and imaging are usually needed to confirm the diagnosis.
Spleen Cancer in Dogs
Spleen tumors are often hidden until they rupture, which can be life-threatening.
Early warning signs may include weakness, pale gums, or sudden collapse. This is considered a veterinary emergency.
How Veterinarians Diagnose Cancer in Dogs
When cancer is suspected, veterinarians use a combination of diagnostic tools, including:
- Comprehensive physical exams
- Bloodwork
- X-rays and ultrasound
- Biopsy or tissue sampling
At Maple Grove Pet Hospital, our team provides thorough and compassionate diagnostics to ensure your pet receives the care they need.
Treatment Options for Cancer in Dogs
Treatment depends on the type of cancer, its stage, and your dog’s overall health.
Common options include:
Surgery
Surgical removal is often the first choice when a tumor is localized and operable.
If the disease has not spread to other areas of the body, surgery can sometimes be curative by removing the cancerous tissue.
Chemotherapy
Chemotherapy targets cancer cells that may have spread beyond the primary tumor.
In dogs, the goal is usually to slow tumor growth and ease symptoms, and treatments are designed to be less harsh than those given to humans, often with fewer side effects.
Radiation Therapy
Radiation therapy uses carefully controlled doses of energy to destroy cancer cells in a specific area.
This treatment is often combined with surgery or chemotherapy and is especially helpful for tumors that cannot be fully removed surgically.
Palliative Care
When curing the cancer is not possible, palliative care focuses on keeping dogs comfortable and maintaining their quality of life.
This may include pain management, nutritional support, and other therapies to help pets enjoy as much time as possible with their families.
How to Prevent Cancer in Dogs
Not all cancers can be prevented, but you can reduce risks by:
- Spaying or neutering your dog can help reduce the risks of testicular or uterine cancers
- Minimizing exposure to toxins and secondhand smoke
Scheduling regular veterinary checkups for your pet is an excellent way to detect signs of cancer early and prevent it.
