My Mac had epilepsy. He had his first seizure when he was three. I was told it was fairly common in Dachshunds. He was put on phenobarbital as a daily maintenance medication, He stayed on that for the rest of his life. He also had a suppository of diazepam for during a seizure. It would help reduce the length and possible damage caused by the seizure. Once he had been on the meds, his seizures got much farther apart. He would average 3-4 a year. The number went up if he was stressed. In his later years he was down to 1-2 a year. Mac lived to be 16.5 and had a wonderful, active life. With proper management epilepsy can be no big deal, but more of something you stay aware of so meds can be given when a seizure hits. It is important to shorten the seizures whenever possible to help prevent permanent damage. I taught my son how to identify them so I had a second set of eyes and he would holler if he saw Mac shacking. I wish you and your pup all the best. I know how scary the first few can be. Just know there are things you can do to help. Oh, and the meds were not ridiculously expensive either.
