Congrats on the new furbaby... Though, as the other posters; Im a bit concerned that he's so young... I got Meka at 9 wks and she was such a handful. I couldnt imagine having a pup so young w/ such little time to be with his mom and other littlermates... Maybe you didnt know how old a pup should be when leaving their mom, and you shouldnt be faulted for that. I'd get him to a vet and get their opinion and go from there. If the breeder is already gone on vacation, there probably isnt to much you can do except give him the best care possible. Hope everything works out for you
