Limit has been displaying some very strange behavior. He will play fine for awhile with everyone and then all of a sudden he starts what looks like resource guarding. It appears that he is resource guarding me, he hovers in between/on my feet or if I'm squatting with the camera, under my butt. He darts out and snarls/barks, hackles up, tail down at the dog and then as soon as the dog turns away from him he races back to me and assumes the same position. Kastle: Pan: The weird stuff: He *only* does this to Kastle and Pan. NEVER to Finn, Eden or Poppy. Ever. In fact, he can be mid-guard against one of the GSDs and the others can run right past him and up to me and hop all over me/climb in my lap etc. He just comes back to his station at my feet and ignores the other three. I've been verbally getting after him or physically blocking him from going after the GSDs. Pan is too sweet though so after Limit starts this, he just stays away. Kastle, however, is a very clingy mommy's boy and will put up with it for awhile and is 100% fine with letting me take care of it, BUT if my back is turned and Limit does it, Kastle will put him in his place - appropriately, but still. I thought it was resource guarding but I couldn't figure out the pattern. Kastle is clearly mine and we have a strong mutual bond but Limit has no issues with Eden and her and I are close too. He has a problem with Pan and Pan and I are not bonded like that. I was looking through my photos from yesterday, in consecutive order from Limit playing with everyone, including Pan, to him "guarding". The only thing I can think of that is the same when he does this is he is "herding" them and one of the GSDs invariably runs over top of him, not hurting him, but tumbling him. From that point on in that play session, Limit is PISSED. He remembers and goes after the GSDs for the rest of the time outside, even though the GSDs clearly don't know what is going on after the initial snark, they are not doing it on purpose. My impression is that he thinks he is protecting himself and hiding in his "safe spot" aka me after driving the bigger males away. Do you think this is what is happening? Anyone seen this before? How should I handle it? I am thinking getting after him for it is not going to do the trick since he feels threatened so I think when he gets that upset, I'll just remove him from the situation. He will "allow" Kastle to come to me, if *I* call him to me, but if Kastle tries to come over without a summons, he is herded off. If I call him, Limit will circle behind him and bark but won't chase/nip and it's more playful (tail up, no hackles etc). I can get them both right next to me and pet them both and he is fine. Since Kastle is not perturbed by Limit's behavior (Pan is, so I'm taking Limit away when he gets snarky), should I keep asking Limit to get over it by having Kastle come into our space and praising them both? Limit is very bright and picked up right away that when I called Kastle to me, Limit was not allowed to snark at him - he watches me and he watches Kastle and I can see him deciding what to do. I just am totally unfamiliar with dogs that hold longer-term grudges vs getting snarky and getting over it. Help please?
