I think Quinn is resource guarding me from Buster. Neither of my two are allowed on my bed much anymore but if Quinn is up with me and Buster goes to get up she'll snark him (the other day she flew at him really hard) She'll occasionally do it when she is lying at my feet and he coems over when I call him, she can switch it on halfway through a training session with him. Quinn's reaction is pretty easy to pick, she pins her ears back, gets extremely tense, her eyes are very hard and she stalks up and stares him down about 2inches from his face, with or without hackles. Her movements are slow and deliberate. It can be really hard to break her out of it, she will normally wait till I call Buster to me (away from her) and then go in to mouth him on the back feet, or sometimes she will load up and snark him in the face. Buster's reaction? If it wasn't so completly obvious and she wasn't inches from his face you would swear he wasn't even aware. He stays very relaxed, averts his eyes and doesn't move or challenge her. As for me? I feel really lost, I've been building an interuptor noise for her the last couple of weeks just to get her attention (mainly to use it if her and Mac are zoning in on each other) I can't go hard on her because she's a hard dog and me getting louder or rougher just sends her over the edge. Sometimes I call Buster away from her to come to me and this usually sends her in to nip his heels and then stalk off. She has a habit of appearing whenever I am giving Buster attention and climbing onto my lap while smiling stupid at him and touching him on the nose with her paws or sticking her nose in his mouth till he bites her gently ont he face... wrestling usually ensues if I let it. She is very good at suddenly appearing and going "YAY! LOVE MEEEE!!!! Arn't I beautiful!?" when buster is getting attention and Buster isn't really pushy like that, its so easy to get distracted by her and he is just happy to wander off. So I'm trying to take more notice of this and send her away when I notice her trying to break Buster and I up. Buster's probably been missing out on the love a bit for probably the last 12 months, I had 6 months of being too busy for anything and then 6 months of working hard on Quinn and poor Buster has got a bit attention neglected so for the past couple of months I've got back into his training and working with him more. And for the last week I've started combinging his and Quinn's sessions, making one of them stay on a mat quietly to the side while I work the other one. So I can recognise when she's being unfairly pushy, should I send her to a place? Should I get up and move away with Buster? Should I put her in a time out? Once she "zones in" on Buster, I think I can probably interupt her with the cue we've been working on, what then? Time out? Send her to place? And if she does load up and have a go at him where from then? I have been thinking of setting up situations where I can work through this with Quinn a bit. I have been trying to keep treats on me and reward Quinn when Buster approaches us or her crate etc. (She can be a little guardy of her crate as she gets fed in there and she guards food HARD) It can be hard because her triggers arn't always the same so its hard to pick create situations to work her.
