A pup shouldn't wean until atleast 6 weeks, and shouldn't go to a home until atleast 8 weeks.Even at that age they're too young. Be sure to keep a close eye on your pup. Don't take him out of the house. He is very young, and will pick up diseases VERY easily.You can put a tick tock clock in with the pup and a warm blanket from the dryer to help. The poor thing wants its mom! Why would you get a pup so small?
