Either one of these things can result in diarrhea. At less than eight weeks, Buttons really should not even be receiving a vaccine as of yet, as that is the age when it is licensed at a minimum. Dietary change should always be done over a gradual period, approximately one week. Diarrhea can also be called by GI parasites in puppies this young. I would bring in a fecal sample to your veterinarian to be looked at to verify if any of this is occurring. If so, a dewormer can be administered and rid Buttons of the nasty bugs. Regarding vaccination, if you are concerned about reactions to the shots just make sure that Buttons is never receiving more than one or two at a time. With larger dogs, I don't hesitate to do up to four at any given time, but with a tiny pup I won't give more than two. Hope this helps.

Great question! If the puppy is between four to six weeks of age, that's still too young for him to get his vaccines. He should be between six to eight weeks of age before he gets his vaccines. I would take him into the vet in two to three weeks to get the vaccines done. As for the diarrhea, he could have intestinal worms causing it, which is common in young puppies. He will need a deworming treatment for it. I recommend Panacur, it's a three day course of treatment you can get OTC at a pet store or your vet's office. He will need a second course of it two weeks after the first to kill all the worms. He should be dewormed every month after that until he is six months old, and then should be dewormed every three months thereafter. I hope this helps!
