Brain tumor are common and often seen in middle age and older dogs however they can also affect the younger one too. If canine has a seizure then it could be the signs that a brain tumor is present.
The most common types that often found in dogs are astrocytomas, oligodendrogliomas and meningiomas. Tumor tend to be wide spread on multiple sites on the brain rather than one spotted position.
Some of the tumor arise directly from the brain tissue while other types spread to the brain by bloodstream since the brain control extensive blood supply.
The severity depend mainly on the brain location where the tumor arise and how fast they grow. Canine seizures can also be caused by other problems such as low blood sugar level or heart problems.

Boxers and boston terriers trend to develop pituitary and glial cell tumors which is commonly called neuroglia while breeds with long nose have a predisposition to benign tumors (meningiomas)
