Thank you for all the great advice. I took him to a petsmart clinic today to get his "last" puppy shots, but the vet there said he still needed another set

According to the paperwork that I got from the breeder, he only needed this last set, but the vet said that he recommends puppy shots until the dog is 4 months old. I was sad, because now it means I have to wait another month to get his last set of shots, plus the additional 2 weeks after that. I can't wait to take him out! But I care about his health so I must wait.
