Ours is a cross yorki and s**tzu born 29 july 2012. was trained to go on pads but lately seems to forget now and then. we regularly take outside first thing in am, after feeding, various times if the day and just before shut down and sleep. We have noticed that she is constantly wanting to nip and bite fingers noses whatever. full of energy plays by herself. has attached herself to wife and now i'm #2 - no problem there. What can we do do stop the constant biting and nipping. Fearful it might continue with age. It is now 14 weeks old, wife wanted a lap dog but not one that is constantly trying to jump up and bite face or nose. What should one do.. Secondly when would expect baby teeyth to come out and be replaced with adult ones. Tks. Dave.
