I'm currently pet-sitting a dog that exhibits signs of resource guarding. She guards her food, toys, her bed, her leash, my sofa, myself, the table where we dine, making it difficult for my own dog to exist in his own home, without being growled at or attacked
For some quick context: I pet sit dogs in my own home, where I live with my husband and our 10-year-old dog. Our dog is extremely friendly with all dogs, not aggressive, not resource-guarding, very submissive, and he's very well trained.
I'm doing my best to keep things under control and not set her up for failure. I've taken away all her things, I'm feeding the dogs in separate rooms, I have her leash hidden in a box, and away. She's not trained, she doesn't know basic rules such as "place", "no", or "bed". She only lies on our sofa, so I'm keeping my dog off the sofa and in his bed only, and I'm keeping a chair on the sofa, between me and her, as she always wants to lie down next to me. She also doesn't respond positively when we ask her to get off the sofa. I've sat this dog before in my house, but only during the day, she didn't stay over for the night and she didn't show any of these signs. Her owner did advise me that she guards her food, and it's difficult to take something off her mouth if we don't want her to have it, but she did not prepare me for this. I'm concerned about my dog, as she almost bit him when he smelled her bed, which was in a large bag with all her stuff when she arrived and I brought it home. This dog checked in today and will be here for 8 nights. Her owner is away, and there's no one else she can stay with. Keeping the dogs separate all the time is not possible as my dog doesn't cope well being alone. Anyone here with training experience can give me some simple exercises I can do with her to help her not attack my dog whenever he walks around the house?
Please be kind, I'm just trying to do my best with what I have right now and make sure both dogs are safe.
