So, my 10wk old GSD ignores me completely over my 3 year old Boston Terrier. It's not just normal "I'm a puppy, this is super fun playing, so I'm not going to listen" It's more like she think's HE'S the Boss, the pack leader, the Alpha, and she want's all his attention, and gives him all of hers, and anything else is secondary. I sware she get's jealous when he sits with me, not cause she want's to sit with me too, but because she wants her buddy back. I put Bo in his crate when I'm working with her, but eventualy she needs to learn to listen to me no matter what ya know? Bo is a good dog, so you think he would be a good influence on her, but all basic comands go out the window if Bo is within 10 feet, which is pretty much most of the day. Should I seperate them? For part of the day, for several days? Forever? Lol.
