Hope someone comes on and gives you some information. I know that tiny ones can have severe reactions if they are given too young. Normally breeders don't allow their puppies to go before 12 wks. Make sure that you have Nutra-Cal or Karo syrup on hand in case he has a hypoglycemic episode. To find more information concerning reactions to vaccinations you could use the 'search' button at the top. I am also one that would probably be back at the vets if I thought that my puppy was ill. Good luck.
