epilisey dog

It is very unfortunate but I do have an epilisey dog, Starry. He has his frist fit at 15 weeks old. I took him to the Vet and the Vet told me he might grown out of it. He is nearly a year old now and he still has odd fits here and there. I am very scare to take him out for a walk, just in case he has a fit and I don't know how to handle the situation. He has a quiet life during the week, he stays at home while the others go out as normal. I only take him out when Colin is around so there will be 2 of us if he needs help.
