We have a few members with pups who have seizures. I sent a message to one to notify her of this thread. Hopefully she can help you out.
Epilepsy is not a death sentence! If that is what it is you will just need to find out what med works best for him. Personally, I would do a consult with a vet neurologist.
Try to think positive...I know it is scary to have a sick pup but try hard to relax. If you are nervous and upset, it will rub off on him.
I will say a prayer for you and your pup. What is his name?
So glad you found YT...you will get lots of support here!
Sometimes it is a bit quiet on the weekends...just hang in there.
