Dogs older than five years are at high risk of developing brain tumors; the average age of affected pets is nine years.

brain tumor in dogs: causes, treatments

Some breeds of dogs are at greater risk of developing major brain tissue than others. Brain tissue from the lining of the brain (known as meningiomas) is often found in dolichocephalic dog breeds, which are characterized by long heads and noses, such as Collie. On the other hand, breeds of brachycephalic dogs, characterized by their shorter appearance and flat face, are more likely to develop gliomas, which are the tissues of the central nervous system.

The condition or disease described in this medical article could affect dogs and cats. If you would like to learn more about how the disease affects cats, please visit the petMD health library.

Symptoms and Types

The most common symptom of a brain tumor in dogs is fainting, especially the first seizure in a dog over five years of age. Other symptoms that suggest a brain tumor include abnormal behavior (e.g., increased violence), altered perception, excessive sensitivity to pain or touch in the neck area, vision problems, circulatory movements, inconsistent movements, and "drunkenness," impaired mobility. Unexplained symptoms such as dysfunction, weakness, and improper urination may be seen.

Causes

The causes and risk factors that can cause brain tissue in dogs are unknown. It is thought that a variety of dietary, environmental, genetic, chemical, and physical factors may be involved, but this is uncertain.

Diagnosis/treatment

Tissue biopsy is the only available way to clearly diagnose brain tissue in dogs. Experimental experiments such as radiographs (x-rays) or ultrasound of other anatomical sites can be used to locate or extract key tissues from other areas that may have spread to the brain. Magnetic resonance imaging (MRI) or computed tomography (CT) of the brain are recommended tests to confirm primary or secondary brain tissue diagnosis.
