Dog Brain Tumor: Making the Tough Decision of When to Euthanize

Dog Brain Tumor When To Euthanize

If your beloved canine is facing the difficult challenge of a dog brain tumor, you may find yourself grappling with the question of when to euthanize. Brain tumors in dogs occur without any known cause, making the diagnosis overwhelming. However, understanding the steps to take after the diagnosis can prepare you for treatments and help you understand the prognosis.

What is a Dog Brain Tumor?

Abnormal cell growth and irregular cell division give rise to a primary tumor in the brain. These tumors can also develop in the skull, pituitary gland, cranial nerves, and the brain’s protective membranes known as meninges.

While the specific cause of brain tumors remains unknown, potential factors include environmental and chemical toxins, dietary factors, a weakened immune system, and genetic predisposition. Breeds with short noses and flat faces, like Pugs and Bulldogs, as well as those with long heads and noses, such as Collies, are more prone to developing brain tumors. Other susceptible breeds include Terriers, Golden Retrievers, and Dobermans.

Different Types of Brain Tumors

Brain tumors can be either primary or secondary. Primary tumors originate within the brain cells and membranes. The most common types of primary brain tumors include Adenocarcinoma, Choroid plexus papilloma, Glioma tumor, Meningiomas, and Pituitary adenoma.

Secondary brain tumors, on the other hand, develop from cancer cells that originate in other parts of the body and spread to the brain through metastasis. They can also develop from nearby non-nervous system tissues, such as cancer of the nasal cavity. When secondary brain tumors are diagnosed, it indicates that cancer has already spread throughout the body. Examples of secondary brain tumors include hemangiosarcoma, mammary carcinoma, and melanoma.

Recognizing the Signs and Symptoms

Brain tumors in dogs can grow rapidly and aggressively, underscoring the importance of early diagnosis to prevent fatality. Initially, the symptoms may be nonspecific and not solely indicative of brain tumors. However, there are specific signs to be aware of:

  • Behavioral changes, including aggression
  • Decreased vision
  • Excessive panting
  • Difficulty swallowing
  • Depression
  • General weakness and lethargy
  • Head tilting
  • Hearing loss
  • Increase in vocalization
  • Loss of appetite
  • Loss of balance
  • Seizures (common early clinical sign)
  • Vomiting
  • Weight loss

As the brain tumor progresses, these signs will continue and worsen, indicating the final stages of the disease.

Diagnostic Procedures

The diagnosis of a dog brain tumor involves various tests, starting with a detailed history, physical examination, and blood work. Blood tests, including a full blood count, help identify any possible infections and evaluate the overall health of the dog’s organs, such as the kidneys and liver.

To make a definitive diagnosis, a biopsy of the mass is usually taken. This allows for a more accurate understanding of the tumor’s malignancy.

Life Expectancy After Diagnosis

The life expectancy of dogs with brain tumors varies depending on the available treatments, tumor size, and extent of its spread. Fortunately, some treatments can significantly improve a dog’s quality of life by reducing symptoms and slowing down the progression of the disease. On average, survival times after diagnosis may range from six months to three years with surgery and radiation therapy, seven months to two years with radiation therapy alone, seven to 11 months with chemotherapy, six to 12 months with surgery, and two to four months with supportive care only.

Available Treatments

In most cases, emergency treatment is necessary due to the increased pressure the growing tumor exerts on the brain, leading to neurological issues. Seizure control is a priority, and specific treatments include inserting an intravenous catheter, administering anti-seizure medications, and providing nursing care to reduce brain swelling.

Other treatment options include:

Radiation therapy and chemotherapy: These treatments aim to shrink the tumor as much as possible and often require daily anesthesia for five days a week, over a period of three weeks. However, there is a rare possibility of side effects, as healthy brain tissue may also be affected.

Brain surgery: This procedure, known as debulking, involves the surgical removal of the tumor after removing a small portion of the skull. However, brain surgery can only be performed by neurology specialists under general anesthesia.

Medical management: Steroids may be prescribed to reduce brain swelling. However, these medications can have side effects such as increased appetite, thirst, and urination. This treatment usually extends the dog’s lifespan by only a few months.

After Treatment: Monitoring and Care

It is crucial for dogs with brain tumors to receive regular check-ups to monitor for any signs of tumor regrowth. Dogs with weakened swallowing reflexes are prone to developing aspiration pneumonia, so close attention to any health changes is essential. Additional MRI and CT scans may be recommended by your veterinarian to assess the tumor’s status and your dog’s overall health.
