5 way shot is all a 3 month old pup needs think its call Durmane Max 5, it's the best on the market bar none, also can give it to old dogs as a buster shot.
8 way shot is good but I would wait till pups are 5 to 6 months old on an 8 way shot, but there again every body has an opinion and u ask and I am giving mine.
Hey True Grit, we went to Revival Animal Health site and found the
Duramune Max5 for half the price of jeffers.com(not cutting anyone down) for the same pack. Thanks Again
