Hello! Our puppy constantly wants to play with our older dog by biting his ears and legs. He doesn’t always want to play but he doesn’t use any string corrections with her. Once she is in “play mode” with him she forgets all commands and manners. I have to grab her leash and pull her away to another room. I try to keep them separated but the older dog always wants to be in the same room because he knows there are treats to be had! I treat the puppy when I see desires behavior. The puppy is 5 mos old and has been through training. I’m at my wits end! When will she learn to just “be” when she’s around the other dog?!?!
