Brain Tumor in Dogs: 12 Symptoms and Treatment Options


While brain tumors in dogs are relatively rare, such a diagnosis is a sad and troubling situation for any pet owner. Veterinary research suggests that while causes can be identified in some cases, most canine brain tumors occur spontaneously for no identifiable reason. When causes can be ascertained, they are usually due to environmental and/or genetic factors.

Canine brain tumors can affect any dog breed, but some breeds appear to be more susceptible to them than others. Boston terriers, boxers, pugs, and other types of dogs with flat facial profiles tend to develop brain tumors at higher-than-average rates.

Symptoms of Brain Tumors in Dogs

In dogs with brain tumors, symptoms tend to appear quickly and worsen rapidly. Thus, it is very important to seek immediate veterinary attention if you notice any of these definitive signs (note: treatment options are listed after the 7 symptoms below):

Symptom: Seizures

Seizures are the single most common symptom associated with canine brain tumors. These seizures are usually acute, meaning that the animal remains conscious while the seizure takes place. They may occur as isolated incidents, or as a rapid series of repetitive seizures. A brain tumor may be suspected if a seizure occurs for the first time in a dog that is five years of age or older.

If your dog suffers a seizure, regardless of its age or health history, you should consider the situation a medical emergency and seek immediate veterinary attention for your pet.
