Hi Elizabeth,

from the way you’re asking I’m assuming that it was diagnosed as epilepsy the first time around? At the age of 5 it would be a likely diagnosis. How was it diagnosed and was it treated in any way?

“The two most important factors in the diagnosis of idiopathic epilepsy
is the age at onset and the seizure pattern (type and frequency). If
your dog has more than two seizures within the first week of onset, your
veterinarian will probably consider a diagnosis other than idiopathic
epilepsy”

Onset of seizures in a dog older than 5 years, it can be metabolic or neurological (a lesion like a brain tumor).

So the question on my mind would be, is it the same thing as it was four years ago or is there something else going on? If it was me I would want to revisit this with my vet.
