Those levels are not high enough to indicate that a liver problem is causing the seizures.

It is most likely that Bogey's seizures are due to idiopathic epilepsy. Idiopathic epilepsy is common and means that the cause of the seizures cannot be identified whereas symptomatic epilepsy can be attributed to a cause.

Dogs with Idiopathic epilepsy usually experience their first seizure at 1 -5 years old. There is no test for Idiopathic epilepsy. It is only diagnosed by ruling out other causes. Typically a vet will not give medication for Idiopathic epilepsy unless the seizures are severe or are occurring on a frequent basis. What they will have you to do is time the seizures and keep track of their frequency. A seizure that last for under 15 minutes is not usually life threatening. If the seizure lasts longer or occurs one right after another (cluster seizures) then they can be dangerous and must be treated right away.

Your sister's vet should do a full blood panel to rule out other causes. If she wants to go further and rule out serious causes that can't be diagnosed with blood work, she can have an MRI done which is expensive and not widely available.

If her vet determines that the seizures are idiopathic, then have her ask for a dose of rectal valium (the valium should be kept out of the light because it will break it down and make it less effective). The valium is only to be administered if the seizure lasts longer than 15 minutes or is particularly violent. This should bring him out of the seizure and will help to prevent lasting damage until she can get him to a vet.
