Hi, everyone... My 4 month old female berner has hit a naughty streak in her training. It feels like overnight she's stopped listening to everything I ask her to do. I know puppies start to get rowdy at the two year mark but it is way, way too early for the Terrible Twos! The worst thing is her behavior on walks. We'll start out great: walking side by side, her sniffing and being calm, etc etc. And then something will just click in her little puppy brain, demanding for (my!) blood. Sometimes I know what triggers it: people greeting her excitedly or acknowledging her in a high pitched voice (the latter I can't really do anything about) and then leaving will cause her to turn on me, and it's not pretty. She'll start jumping up and grabbing onto my clothes with her teeth, tugging on them. She doesn't understand how sharp her teeth are, or her own strength, so when she scrapes my skin it really hurts. All my clothing has holes in it, and my arms have scrapes everywhere. She also goes for pant legs. Sometimes this is triggered randomly, or when I stop because she is pulling on the leash. Sometimes I can say sit, down, etc and she'll stop and do the command, but be right back at it the moment I try to start the walk again. I've tried shortening the leash away from me so she can't attack me like a little hell hound and tried to wait it out with some success, but then it'll just trigger all over again when someone acknowledges her in that baby voice (which happens a lot, since puppy). I've tried running her in the yard before walks, but she still does it. It's really putting a strain on our relationship... I love her but I'm starting to dislike her over this... When I get back from walks I just want to scream into a pillow. We can't even take long walks because she'll just keep doing this over and over again. I try to keep it positive on walks (thus keeping them short before I get frustrated) but it's getting harder and harder... My Australian Shepherd never did this, so I don't know what to do... help!!
