Thanks for your reply its very helpful

I think I just need to take him to a vet and talk it over with them. I'm just scared I am going to be pushed into something by the vet because of scare tactics or something like that so I'm trying to get info first.
Looking at the sticker from the vaccine he already recieved at 6 weeks it says: Canine Distemper, Adenovirus Type 2, Parainfluenza, Parvovirus vaccine.
The adenovirus I'm guessing is the hepatitis? The breeder kept saying something about the 5 way vaccine, which seems dangerous to me because I thought they should only be vaccinated with one or two at a time because its hard on their immune systems especially when so young.
So i'll need the hepatitis, parvo and distemper one more time? or two more times? and then I'm going to try and get the rabies as late as possible so he can grow some first...
