Hi, Looking for a bit of advice or just to see if anyone else has this problem. This is a long one, sorry. I have 7 month old GSD. Shes very smart, sometimes goofy and I love her to pieces. Recently she has started chewing at me like a dog possessed. I don't think it's aggression although I could be wrong. We will be playing or I could just be sitting on the couch and she will just drop the toy jump all over me nipping at my arms, shoulders hands, grabbing my whole arm in her mouth and its getting painful at times. I've tried the yelping it just seems to spur her on. I've walked out the room til she calms down and entered again and if she does it again straight back out. Usually if I give the sit command she does with no hesitation but during this frenzy she listens to nothing, i say no, I tell her to sit, ive tried to redirect her attention elsewhere and she just keeps going at me. She doesn't do this with my partner. If he tells her no she stops, if he says down, or sit she listens it just seems to be with me. I know it sounds silly but I feel like she doesn't like me sometimes even though she follows me everywhere, she's always by my side. I'm the one who feeds her most of the time due to our work routine, i walk her more often, i did the majority of her training but it's like somethings switched in her and I don't know what i did wrong. Im on the waiting list for 2 behaviour trainers, I'm just not sure what to do until then. She was at it about half an hour ago. We were playing with a stuffed animal that I hide on me and she has to sniff and find it then when she finds it we play fetch with it, but as usual she just drops the toy and goes for me, tried everything again, I ended up locking myself in the bathroom to cry. I know it sounds stupid but it's really upsetting me. She was crying at he bathroom door and as I opened it she came in and smothered me with kisses and as I type this she is laying cuddled at my feet. Jekyl and Hyde springs to mind lol. Has anyone else had something like this happen? I'm obviously doing something wrong, I just need help to help her to stop. Sorry for the long winded story.
