Dr. Ian Dunbar says the most crucial socialising phase of a puppy's development is 8 to 12 weeks. So if the breeder is going to socialise them during this period fine leave them longer but I think this leave to 12 weeks is where a lot of the potty training problems come from. A pup of 9 weeks is plenty old enough to leave Mama, if it is healthy! If it is not healthy you dont want it. |
