The important thing is to keep the dog from falling and hurting itself. As long as it is on the floor or ground, there is little chance of harm occurring. If seizures continue for longer than a few minutes, the body temperature begins to rise. If hyperthermia develops secondary to a seizure, another set of problems may have to be addressed. There are many, many causes of seizures.
Epilepsy is the most common and of least consequence to the dog.
The other extreme includes severe diseases such as brain tumors. Other problems that can cause seizures or episodes that look like seizures may be caused by Hypoglycemia, electrolyte imbalances, Cardiovascular problems, Central Nervous System infections and a few other causes. Fortunately, most are due to epilepsy. When a seizure occurs, we begin by taking a thorough history concentrating on possible exposure to poisonous or hallucinogenic substances or history of head trauma. These tests rule out disorders of the liver, kidneys, heart, electrolytes, and blood sugar level.
