Good morning! I say that as we are in our 2nd week of adding a Golden Doodle puppy to our household. She is an absolute beauty but an incredible handful! We got her at 8 weeks and I soon became the playmates she left from her large litter. We are desperate to get her aggressive biting and nipping under control. My arms and legs are ripped to shreds! From waking at 6am until 9am it is all about trying to play and train her. She has learned to sit and lay down. Have tried working on targeting but quickly turns into biting my hand. She gets excited when playing and immediately starts biting my arms and ankles. At first I tried crying out but that seems to get her even more fired up. If I tell her to sit and mark it and provide a reward, she stops for the moment and than right back at me! Have tried redirecting her and it works for a while but she is wearing us down. Additional issue is we have 2 senior small dogs and they are up on the couch so she is constantly trying to get up there. Have tried teaching her up and down. Both work, but once I take a break she is right back with her paws up on the couch pulling on the cloths we have covering it. Ordered this course this week when she was snoozing like now and am seeing some benefit but really need additional guidance to get her under control. She is growing fast and will be an estimated 75lbs full grown. Thanks
