This was years ago but my dog had (idiopathic) seizures that started at the age of 9 months, he did well on a low dose of phenobarb and lived to be 14.

He was never drowsy or had any side effects, the vets may have other medications they use now.
I would consider asking your vet about treatment options, or have him refer you to a neurologist.

Otherwise the dog suffers, it’s like a fire storm in the brain when they are experiencing a seizure. Uncontrolled seizures can cause more neurological damage…..
