Many puppies are resilient and would have no problem, but you won’t know if yours is one of them or not until you get it home, and puppies are fragile too, getting seriously ill very quickly from diarrhea.
As for the Answers Goat Milk, adding it to the kibble is a good idea. It has probiotics and enzymes that really help protect the gut. For the first week I would only add it as a topper, less than 20% of the meal. If you see that your pup does not get soft stool from the move, then you can plan to move ahead with the switch a little faster, but I would still wait a solid 3 or 4 days.
