If your chihuahua is having regular seizures this is know as epilepsy. If the epilepsy is the result of an illness, then it is called secondary epilepsy. However, if there is no known cause then you may hear the vet refer to it as idiopathic epilepsy or primary epilepsy. Your vet will put a treatment plan in place for your dog.

The most common reason for seizures in Chihuahuas is idiopathic. It’s in the Chihuahua’s genes, and there’s no medical explanation. There are medical reasons for other episodes, such as liver disease, inflammatory brain disease, hypoglycemia, and brain injuries.
