I'm sorry, I also posted this in another section of the forum but I think this is where it should be. We are having troubles with our 14 week old Aussie biting and nipping. She is not being aggressive but simply playing... she is hurting us, however. Not to mention, ruining some of my daughters' skirts etc... We've been trying to yelp loudly and say "OUCH!" but it seems to only get her more excited. Advice?
