[QUOTE=Breezeaway;3468896]Also I have had to separate some puppies at about 9 weeks. The can start picking on one in the litter and they can get pretty vicious if you have 4 gang up on one. They will pick on him so much that he then becomes introverted and shy. Hides behind things to get away from them and then that becomes a habit and it is what he learns from them, he becomes shy and learns to hide to be safe. Not a good habit to learn. Maybe that is the reason some people place them earlier. [QUOTE]
That is EXACTLY how I got my own first yorkie!!! I've not heard anyone else describe the same situation on here. She was from a litter of 4 females. The other 3 pups and the mom all picked on her. She was so skittish & timid. I went to look at the pups to see if there was one I wanted to put a deposit on and ended up leaving with her that same day because of that exact situation. She flourished once I took her home and reveled in the attention of my kids. The breeder called once a week to check on us to make sure we were doing okay. Then at Christmas, when we took her back to see her mom & the sister they had kept, the breeder couldn't believe she was the same pup.
