Primary brain tumors in dogs form in the cells of the brain and its lining. Secondary tumors are those occurring elsewhere in a dog's body, typically from cancer, and then spreading to the brain. The most common sign of a brain tumor is a seizure and usually occurs in dogs over five years old.

Other behavioral symptoms depend on where the tumor is located within the brain. Tumors in the forebrain cause a host of behavioral issues since this is the area where thinking takes place.

Symptoms of Forebrain Tumors

Seizures
Loss of learned behavior
Less awareness
Disorientation and confusion
Drop in activity level
Overly thirsty
Depression

Tumors in the brainstem affect the ability to regulate motor functions like walking.

Symptoms of Brainstem Tumors

Difficulty Swallowing
Loss of balance
Weakness on one side of body
Problems moving the eyes
Facial paralysis

Tumors located in the cerebellum effect coordination of movements, balance and posture.

Symptoms of Tumors in the Cerebellum

Head tremors
Wobbliness: swaying of trunk
Head tilting
Decreased appetite
Vomiting

Other indications of brain tumors in dogs arise because of the size of the tumor and how quickly it is growing. You will see changes in your dog's behavior and temperament, such as:

irritability and aggression
depression
pressing his head against a hard surface
compulsive walking
sensitivity to touching
