Dog Brain Tumor Life Expectancy: How Long Can Dogs Live With a Brain Tumor?

Canine brain tumors are a tragic disease that affects many dogs. A dog’s life expectancy from the onset of symptoms depends on the type and location of the tumor, if it has metastasized and how advanced the disease is.

The life expectancy of a dog with a brain tumor is different for every dog, but it depends on the size of the tumor, where in the brain it is located, and how fast it grows.

In most cases, a dog with a brain tumor will require surgery or radiotherapy. With treatment, the outlook is generally poor with a median survival time of only 8 months. With supportive care alone, the average life expectancy is even less, at around 2 months.

​Unfortunately, with most types of brain tumors in dogs, the outlook is not good. This is especially true for gliomas, which are the most common canine brain tumors. These tumors can cause hemorrhaging in the brain and can be fatal. Medications used to treat brain tumors in dogs may only prolong their lives for a few weeks or months at best.

What is the progression timeline of a dog with a brain tumor?

In its early stages, a tumor may cause your dog to have difficulty walking, experience changes in mood, and have prolonged sleeping.

In the advanced stages, a dog may exhibit multiple symptoms including head tilt, poor coordination and circling or disorientation. They may also develop seizures, begin losing sight or show rapid eye movement (nystagmus).

The end stages of a canine brain tumor are often characterized by the following symptoms: seizures, head pressing, sudden behavioral changes such as fear or aggression, increased weight loss and disorientation.

When to put a dog down with a brain tumor

The most important thing is your dog’s quality of life. Treatment that could prolong their life may also prolong their suffering. If you feel that the treatment or surgery will cause more suffering than letting go, then it may be time to let go.

Treatment for a dog with a brain tumor includes surgery, radiation, and chemotherapy, but it is rarely successful. Surgery can be used to treat the tumor, but if the tumor has spread and is affecting your dog’s vision or causing seizures, then there may not be enough time left to make a difference in the quality of life.

Radiation and chemotherapy can extend your dog’s life expectancy, but can also cause side effects that are difficult for dogs to cope with such as fatigue and nausea. These treatments may also extend your dog’s life for a few months, but will not increase the quality of their life.

Most owners want to do everything possible to help their dogs fight the cancer. But if you feel it is time to put your dog down with cancer, do so at home so you can spend as much time as possible together.

If you are unsure what to do, ask your veterinarian for advice. Your veterinarian has seen this situation many times before and they will give you their honest opinion based on what information they have.

Is it worth giving a dog Chemo?

The main reason to treat cancer in dogs with chemotherapy is that it can help to reduce their pain and improve their quality of life. Cancer is unfortunately often incurable in dogs. In these cases, chemo may still be recommended as a way to help ease your pet’s symptoms resulting from the disease.

Treating cancer in dogs with chemotherapy helps to slow down the development of the cancer, but unfortunately, it will not cure your pet. However, early detection can help with treatment, recovery, and prolonging your dog’s quality of life.

Treatment can take several months, during which time most owners will have to make drastic changes to the life their dog has previously enjoyed. In order to maximize your dog’s chances of survival, it is imperative that you look for treatment from an experienced veterinary oncologist, who can carefully monitor your dog’s progress and tailor treatment accordingly.

The most important thing is to start treatment as soon as possible. The earlier you start treating your dog, the better the chance of avoiding serious complications and increasing their life expectancy.

Of course, this doesn’t mean you should throw money at the problem. If your dog has been diagnosed with a brain tumor, speak with your vet about treatment options and decide what’s best for your dog’s specific needs.

What are the treatment options?

Treating a dog with a brain tumor depends on the type of tumor and its location. Your vet will conduct diagnostic tests like an MRI, CT scan, and biopsy to determine the exact nature of the growth.

Treatment options include medication, radiation therapy and surgery. Depending on the type of tumor, your vet might recommend a combination of treatments to ensure the best outcome for your canine companion.

Your dog’s veterinarian may recommend surgery to remove it entirely. After surgery, radiation and/or chemotherapy may be recommended to ensure that all of the cancerous cells have been destroyed. Some dogs may go into remission while others will die from brain cancer within months of diagnosis. A dog’s reaction to treatment will depend on where the tumor is located and how aggressively it has grown.

In some cases, it might be best to let nature take its course rather than subjecting your dog to further medical treatment.

Are brain tumors in dogs fatal?

A brain tumor can be difficult to detect, especially in dogs. The earlier it’s caught, the better your dog’s chances of survival. Brain tumors in dogs can be benign or malignant. A benign brain tumor is noncancerous, but it can still cause serious complications and lead to death. A malignant brain tumor is cancerous and potentially life-threatening if not addressed quickly by a veterinarian.

Is a brain tumor painful for a dog?

The short answer is yes, a brain tumor can be very painful in dogs.

Depending on the stage of cancer, your pet may be in a lot of pain, which you’ll probably notice through his behavior — whimpering, crying when touched, and avoiding contact with others. In addition to pain medication, your veterinarian can recommend anti-inflammatory drugs to manage his discomfort.

How does prednisone help a dog’s brain tumor?

Prednisone is a corticosteroid that is most commonly used in the treatment of many types of cancers including lymphoma, mast cell cancer, and various skin cancers like hemangiosarcoma and melanoma.

Prednisone reduces inflammation and suppresses the immune system. This can reduce swelling, which can help relieve pressure around a tumor. In addition, when inflammation around a tumor decreases, it can help reduce symptoms associated with the brain tumor such as pain or seizures.

What are the symptoms of a dog with a brain tumor?

If your dog is showing symptoms of a brain tumor, he may be in pain. There are other symptoms as well, though, and they can be easy to miss.

Early signs of a brain tumor include:

  • Seizures
  • Behavior changes
  • Head tilt
  • Vision changes
  • Dizziness
  • Stumbling or loss of coordination
  • Lethargy
  • Vomiting
  • Circle walking (walking with no apparent direction)

Conclusion of brain tumor in dogs

Finding out your dog has a brain tumor is devastating, and you’ll want to know what options are available for treating it. The outlook for dogs with brain tumors is unfortunately not very good. The average prognosis is about three to six months, though gliomas tend to be more aggressive than meningiomas and the survival time tends to be shorter. However, some dogs are able to live a few years after the diagnosis if their brain tumors are caught early and they receive prompt treatment. Even though the prognosis isn’t great, there is still hope that your dog can live a good life for as long as possible, so don’t give up on him right away.
