Pheochromocytoma in Dogs: What You Need to Know in 2023
Pheochromocytoma is a rare but potentially life-threatening tumor that affects the adrenal gland in dogs. Though this condition has been around for centuries, it has only recently been diagnosed with increased frequency due to advances in medical technology. As a pet owner, it is important to be aware of the signs and symptoms of this condition so that you can get your dog the medical attention they need as soon as possible.
In 2023, pheochromocytoma is most commonly found in middle-aged to older dogs, though it can affect any breed, any age, and any gender. The most common breeds that are affected are Boxers, Boston Terriers, and Doberman Pinschers, though any breed can be affected. The most common symptom is an increase in blood pressure, though other signs may include weight loss, excessive thirst, appetite changes, and an increase in urination.
If you suspect that your dog may have pheochromocytoma, your first step should be to contact your veterinarian. Your veterinarian will likely perform a physical exam and some blood work to look for elevated levels of cortisol, a hormone released by the adrenal gland. They may also recommend imaging studies such as an ultrasound or a CT scan to evaluate the size and location of the tumor.
If your veterinarian suspects pheochromocytoma, they will likely refer you to a specialist for further testing. The specialist may order additional tests such as a chest x-ray or an MRI to get a better look at the tumor. They may also order a urine sample to check for elevated levels of catecholamines, which are hormones released by the adrenal gland.
Treatment for pheochromocytoma typically involves surgical removal of the tumor. If the tumor is small, it can often be removed with a minimally invasive laparoscopic procedure. If the tumor is large or located in a difficult-to-access area, the surgeon may need to perform an open surgery. In some cases, radiation or chemotherapy may be recommended to help reduce the tumor.
Preventing Pheochromocytoma in Dogs
The best way to prevent pheochromocytoma in dogs is to keep your pet as healthy as possible. Make sure your pet is up-to-date on their vaccinations and has regular checkups with their veterinarian. Try to keep your dog’s weight at a healthy level and feed them a high-quality diet. Lastly, schedule regular blood work with your veterinarian to check for elevated levels of hormones, which could be an early warning sign of pheochromocytoma.
