JD--but what does 6 months have to do with it? I thought puppies could be vaccinated at 3 months?
Honestly, I have no idea. Vaccines are usually a series of shots at specific times over the first 12-16 months of the life of the dog. Puppy shots can begin in the 6–8-week age range as most well-bred dogs will have some vaccines prior to being sold/adopted when they are in the 8–10-week age range. The CDC could be all wrong with the timing but that is what they came up with.
lcote, one can thank the politicians, the DOT and the DOJ for the loosely written ADA act that passed in 1990. Well-intentioned in many cases but they created a mess with the loosely written Service Dog provisions. Emotional Support Animals is an even bigger mess.
