The cause of the condition is unknown. This is called being idiopathic. However, larger breeds suffer from the condition more than smaller breeds. Also, middle-aged and older dogs develop the condition more than younger dogs.

Treatments for Oral Chondrosarcoma in Dogs

Firstly, your vet will ask about your dog’s symptoms. Secondly, your vet will ask about your dog’s full medical history. This will include breed-specific problems.

Thirdly, your vet will carry out a full physical examination. Additionally, X-rays can be used to highlight any problems. Ultimately, your vet will need to take a deep tissue sample from your dog to analyze and confirm the condition.

Generally, treatment focusses on removing the tumor. This is a surgical procedure. In some cases, parts of your dog’s jaw may need to be removed.

Additionally, your dog will need oral pain medication while they recover. This will be prescribed by your vet. As always, if your vet prescribes your dog any medicine, make sure to stick to the correct dose and frequency instructions. Also, complete the full course of medicine.

While recovering at home it is important to provide your dog with a quiet and calm environment. Also, your dog’s exercise might need to be limited at first.
