Joint Cancer (Synovial Sarcoma) in Dogs What Causes Joint Cancer In Dogs and How To Overcome It?

Joint Cancer (Synovial Sarcoma) in Dogs

As much as cancer affects humans, it also affects dogs. A painful type of cancer is joint and bone cancer. In this article, we learn more about this joint disorder in this article.

Millions of humans and animals throughout the world suffer from the debilitating disease of cancer. While cancer in humans is widely studied and discussed, it is also a significant concern for our furry friends. In fact, cancer is the main culprit in why dogs under the age of two pass away. One type of cancer that can affect dogs is joint cancer, which can be particularly painful and devastating. 

This article will discuss dog joint cancer, including its origins, symptoms, diagnosis, and available treatments.


Dog joint cancer has no known etiology, and it frequently results from a combination of hereditary and environmental factors. The following are some factors that could contribute to canine joint cancer:

  • Genetic predisposition: Certain dog breeds, including Bernese Mountain Dogs, Rottweilers, and Golden Retrievers, are more prone to joint cancer than other breeds.

  • Age: Dogs who are older have a higher risk of having joint cancer. Dogs older than six years old tend to develop joint cancer more frequently.

  • Environmental considerations: A dog's risk of acquiring joint cancer may be increased by exposure to certain environmental variables, such as radiation or toxins.

  • Obesity: Overweight dogs may be at a higher risk of developing joint cancer.

  • Prior joint trauma: Dogs that have previously experienced joint trauma or injuries may be more likely to develop joint cancer in the afflicted region.

  • Hormone imbalances: Particularly in female dogs that haven't been spayed, hormonal imbalances may contribute to the development of joint cancer.

Signs of Bone Cancer in Dogs

The signs of osteosarcoma in dogs can be similar to those of other joint diseases, making it challenging to diagnose. A few of the common symptoms of bone tumors in dogs are:

  • Limping or lameness: Joint cancer can cause dogs to limp or become lame, particularly after periods of rest or exercise.

  • Swelling or stiffness: Dogs with osteosarcoma may experience swelling or stiffness in the affected joint, which can make it difficult for them to move comfortably.

  • Pain: Joint cancer can cause dogs to experience pain in the affected area, which may be accompanied by vocalization and aggression in extreme cases.

  • Decreased mobility: As joint cancer progresses, dogs may have difficulty moving around, jumping, or going up the staircase.

  • Loss of appetite: Dogs with bone cancer may lose their appetite, which can result in weight loss and other health issues.

  • Lethargy: Joint cancer can cause dogs to become lethargic or tired, which can be a sign of pain or discomfort.

  • Behavioral changes: Dogs with joint cancer may exhibit behavioral changes, such as increased irritability or reluctance to be touched.

Treatment Options

The course of treatment for canine joint cancer is determined by the severity of the condition, the dog's age, general health, and other factors like the size and location of the tumor. The following are some typical dog joint cancer treatments:

  • Surgery: In the case of bone cancer in dogs' legs, surgical removal of the tumor may be possible. This may involve partial or complete removal of the affected limb. 

  • Radiation therapy: Radiation treatment is an effective therapeutic alternative to or in addition to surgery. During this procedure, the tumor is diminished, and high-energy radiation is used to kill cancer cells.

  • Chemotherapy: Chemotherapy employs drugs to eradicate cancer cells. It can be used separately or in combination with other treatments. Chemotherapy is routinely used to treat cancer that has spread to other parts of the body.

  • Pain management: Pain management is an essential part of treating joint cancer in dogs. This may include the use of pain medications like Meloxidyl, Dexamethasone, or Prednisolone. However, in order to control discomfort and increase mobility, physical therapy or other methods are required.

  • Supportive care: Dogs with joint cancer may require supportive care, such as nutritional support, hydration therapy, or other treatments to help them maintain their quality of life.

Prevention Tips

Unfortunately, there is no guaranteed way to prevent joint cancer in dogs. However, there are various actions dog owners may take to lessen the likelihood that their canine companion will have this illness. Here are some suggestions for prevention:

  • Maintain a healthy weight: Obesity can increase a dog's risk of developing joint cancer, so it's essential to keep your dog at a healthy weight through a balanced diet and regular exercise.

  • Provide a healthy diet: Feeding your dog a healthy diet that is rich in nutrients can help support their overall health and reduce their risk of developing cancer.

  • Reduce your dog's exposure to environmental toxins: Cancer in dogs can be increased by exposure to specific chemicals or toxins. Try to keep your dog's environment clean and free of toxins, and try to avoid exposing them to dangerous substances.

  • Regular veterinary examinations:  Regular check-ups with a veterinarian can help identify joint cancer in its early stages, increasing the likelihood that it will respond favorably to treatment.

  • Early intervention: It's critical to seek veterinary care as soon as your dog exhibits any symptoms of joint pain or movement problems. The management of joint cancer and the quality of life for your dog can both be enhanced by early detection and therapy.

While these prevention tips cannot guarantee that your dog will not develop joint cancer, they can help reduce its risk and improve its overall health and well-being.
