My Lady has been epileptic for nine years so I know more than I'd like to about the disease.
How old is Bailey? True epilepsy in a dog under one year old is extremely unusual. Seizures are usually a symptom of an underlying disease like a liver shunt, hydrocephalus, hypoglycemia, etc.
What tests did your vet do? Simple bloodwork often won't reveal liver disease. A bile acids test is essential for any dog who exhibits any signs of liver disease. A thyroid panel is also necessary as thyroid imbalances can also cause seizures.
If all the test come back negative and your vet is convinced that Bailey is epileptic, he needs to get on seizure medication asap. He is having seizures too often not to. "Kindling" is a phenomenon where the brain actually learns to have seizures by having seizures. Every time Bailey has a seizure, his brain rewires itself to make a path so it is easier to have the next seizure. This leads to more frequent seizures and eventually cluster seizures which can be very dangerous.
Kindling is when the seizure focus in the brain develops strong enough pathways that it makes it easier for the seizure to occur -- almost as if the brain "learns" to seizure. It is possible that by controlling seizures quickly through the use of medications that these effects could be stopped and that may lessen the amount or duration of need for seizure control medications.

I strongly suggest you find another vet as soon as possible.
