He looks like he's 6 weeks. So tiny. I could be wrong though. My babies are a little fluffier at 8 weeks. But what in the h??? Is your breeder doing letting you take home a 8 week old puppy anyways?!!!! That's just too young. Most pups on here that are sold or bought are 12 weeks or older. Some breeders like to post pics of babies at different ages though. You should have asked your breeder to keep your baby till it was 12 weeks. There's so much your babies missing out on being taken away at such a young age.
By the way your baby is darling!
