As a caregiver, you’re likely already familiar with the numerous health issues that can affect your canine companion. But today, we’re going to delve deeper and discuss a specific topic: bone cancer in dogs.
What is Bone Cancer in Dogs?
Bone cancer, or osteosarcoma, is a fast-growing and aggressive type of cancer that typically affects large and giant breeds of dogs. It develops in the skeleton, often occurring in the limbs, and can cause pain, lameness, and swelling.
- Osteosarcoma is the most common type of bone cancer in dogs, accounting for about 85% of all cases.
- Chondrosarcoma, fibrosarcoma, and hemangiosarcoma are other types of bone cancers that are less common.
Causes of Bone Cancer in Dogs
While the exact cause of bone cancer in dogs is still unknown, several factors are believed to increase the risk:
- Age: Bone cancer is more common in older dogs.
- Size: Larger breeds are more likely to develop this disease.
- Gender: Male dogs have a slightly higher risk.
- Genetics: Certain breeds, such as Rottweilers, Greyhounds, and Saint Bernards, are genetically predisposed to bone cancer.
| Risk Factor | Description |
|---|---|
| Age | Older dogs are more susceptible |
| Size | Larger breeds have higher risk |
| Gender | Males are slightly more at risk |
| Genetics | Some breeds are genetically predisposed |
