Hi all, Dotty was a 'perfect pup' 3 days ago I thought we had turned a corner in as much as the biting/nipping etc. and house training has been brilliant. However she has turned into demon dog:mad5:! She is really nipping everyone again. Pulling and biting on clothes. Growling when she does. She really barks when she is told off (but she seems to be in the play position; paws to the floor, bum in the air). This is just about constant for the last few days. I know she is teething as she lost a tooth in my Daughters jumper! And her breath is quite stinky (fishy; I read that is teething). She really isn't a nice puppy to be around right now. Any tips? Will this pass? Bearing in mind this is just about all the time other than when she is sleeping what can I do?
