I had a dog that was on a daily low dose of phenobarbital from the age of 9 months till her death at 12. No side effects observed at all. No drowsiness…nothing. No change in personality.
If you are comfortable with your regular vet and he has diagnosed her with a seizure disorder I would go by his recommendations.

PS: I had another dog that would go around trying to eat the carpet and such when she had an upset stomach, she had neurological issues related to Lyme disease.
