Question: What is the best age for a puppy to leave the litter?
Answer: Eight weeks is the minimum age for a puppy to leave the litter. It is also illegal in some states/areas for breeders to sell any puppy under the age of eight weeks. For maximum benefits though, it really is best to wait until twelve weeks before separating a pup from his mother and littermates. Puppies learn restraint and proper pay, including some bite inhibition from each other. For a well adjusted family member, leave him with his family until he's twelve weeks old.More Dogs Q&A
