Ok so my puppy Midnight (6 month old lab mix) has this odd behavior regarding bones and treats with my older dog Sarah (5 years old, beagle). Midnight loves her some bones, she's also very submissive to Sarah (neither one is trying to be alpha). Sarah will let her know when she's being annoying and Midnight will totally lay down on her back, sometimes preemptively knowing that what she's doing will annoy Sarah. Like my kids! Now if I give both dogs the exact same bone, Midnight will completely ignore the one I gave her and be totally fixated on the one Sarah is chewing. She'll stand right next to her watching in an almost obsessive fashion. When Sarah is done, she will swoop in and take the bone Sarah was chewing leaving the bone I gave her completely untouched. Then if Sarah takes the bone that Midnight ignored, she'll obsessively stare and stalk her until she finishes then take it to chew it. I will call Midnights name and it'll snap her out of her trance but then she goes back to it. I have pretty much taken to having them chew in different rooms. It helps that Sarah isn't that much into bones. Midnight is a heavy chewer. Why is she stalking/staring and what can I do about it?
