How long does a dog live with a brain tumor?

by
What is the prognosis? The prognosis for brain tumours in dogs is poor, with a median (average) survival time of around two months with supportive care alone. However, with treatment, the vast majority of dogs can be significantly helped.

Canine brain tumors are a tragic condition that many dogs suffer from. The type and location of the tumor, whether it has spread or not, and how far along the disease is determine a dog’s life expectancy after the first signs appear.

Every dog has a different life expectancy when they have a brain tumor, and it varies according to the size, location, and growth rate of the tumor.

A dog with a brain tumor will typically need surgery or radiotherapy. The prognosis is typically poor, with a median survival time of only 8 months, even with treatment. The average life expectancy is even lower, at about two months, with only supportive care.

Unfortunately, the prognosis is poor for the majority of canine brain tumor types. This is particularly valid for gliomas, the most prevalent type of canine brain tumor. These tumors may be fatal and may result in brain bleeding. Dogs with brain tumors may only be given a few weeks or months of life-extending medication at most.

Symptoms & Diagnosis

Symptoms of a brain tumor in dogs can vary. The initial signs of a brain tumor in your dog include any of the following:

  • Altered behavior
  • Aggression
  • Abnormal pupil size
  • Decreased cognitive function
  • Acute seizures
  • Difficulty walking
  • Hearing loss
  • Blindness

    • Proper diagnosis begins with a thorough examination by your veterinarian. Examining the pupils and how they react to light, measuring limb extension, taking blood tests, getting x-rays to see if the cancer has spread to the lungs, and having a CT or MRI are some examples of what may be done.

    There are a few treatment options that can be used after a diagnosis has been made. More often than not, emergency treatment is required. For this reason, dogs frequently exhibit acute seizures brought on by the tumor itself. Slow-growing tumors may alter the pressure inside the brain, which may result in seizures. Usually, the following actions are taken to treat and eliminate the causes of canine seizures:

  • Placing an IV catheter
  • Checking blood sugar
  • Administering IV anti-seizure medication to stop the seizures
  • Providing medication and initiating comfort measures to reduce brain swelling

    • There are five standard methods for treating the tumor itself after seizures are under control:

  • Medical Management: This option focuses on managing the pain in dogs and other symptoms associated with the tumor in an effort to increase the dog’s quality of life. Unfortunately, this is a method of symptom management and thus the life expectancy of pups under this method of treatment is merely a few months.
  • Traditional Radiation and Chemotherapy: Certain veterinary hospitals offer radiation and chemotherapy for dogs, which requires general anesthesia to help radiate the brain. Under a typical radiation treatment schedule, each treatment lasts a couple minutes and will occur daily, five days a week for up to three consecutive weeks. This method may help extend your dog’s life by several months, depending on how they respond to the treatment. However, albeit rare, there is also potential the radiation impacts healthy brain tissue too, which could cause negative side effects.
  • Brain Surgery: Brain surgery for dogs is not nearly as advanced as brain surgery for humans. Dog’s must be put under anesthesia when undergoing this kind of invasive procedure. Upon undergoing anesthesia, the surgeon will take out the tumor from underneath. If successful, this method also yields the potential to increase your pup’s life expectancy. However, it can be costly and is typically only done by specific, certified surgeons. This method is also not without its risks, which include worsening seizures and surgical complications.
  • Stereotactic Radiation Therapy: This form of radiation therapy is highly specialized and involves brief anesthesia for only a few days. It directly targets the tumor, rather than the entire brain (including its healthy tissue). Naturally, it has a greater chance of success than traditional radiation, but it can be quite expensive.
  • Euthanasia: While it may garner mixed opinions, euthanasia is nonetheless an option some dog owners elect to proceed with due to the severity of the symptoms and a bleak prognosis.

    Are brain tumors in dogs fatal?

    Finding a brain tumor can be challenging, especially in dogs. The earlier it is discovered, the greater the chance of survival for your dog. Brain tumors in dogs can be benign or malignant. Even though a benign brain tumor is not cancerous, it can still have life-threatening complications. If a malignant brain tumor is not treated right away by a veterinarian, it could be cancerous and even fatal.

    FAQ

    What are the final stages of brain tumor in dogs?

    Seizures, confusion, sedation, instability, weakness, and, as the condition worsens, stupor, coma, and eventual death are among the symptoms. Seizures in dogs may be the only indication of a brain tumor.

    How Long Can dogs survive with brain tumor?

    With only palliative care, the average survival time for a primary brain tumor is three to six months, or five to twenty-eight months with radiation and/or surgery. Unfortunately, secondary brain tumor-affected dogs rarely make it past a month.

    Are brain tumors painful for dogs?

    Symptoms and Types Other indications that a brain tumor may be present include strange behavior (e g. increased aggression), altered consciousness, heightened sensitivity to pain or touch in the neck region, vision issues, propulsive circling motions, uncoordinated movement, and a “drunk,” unsteady gait are some of the other symptoms.

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

    The most common sign of a brain tumor in a dog is seizures.

    • Abnormal behavior/mental activity.
    • Abnormal vision.
    • Circling.
