However, I can give you some general information that might be helpful:
* Hemangiosarcoma is a serious and often aggressive cancer. It usually affects the spleen, heart, or liver, but can occur in other areas, including muscles.
* Treatment options for hemangiosarcoma depend on the location, size, and stage of the cancer. Surgery is often used to remove the tumor, but it may not be curative, as the cancer can often spread.
* Prognosis for dogs with hemangiosarcoma varies. The survival time can range from weeks to months, depending on the stage and location of the cancer.
* Finding a veterinarian experienced with hemangiosarcoma is crucial. They can provide the best diagnosis, treatment plan, and support for you and your dog.
It's essential to discuss your dog's condition with your veterinarian. They can provide the most accurate and relevant information based on your dog's individual case and medical history.
