I recently adopted a Macau Greyhound (Tres) who has spent six years at a race track, which is longer than typical racing dogs . He’s very sweet and loves people . I feed him in a separate room so he’s had no interaction with my other dog (Taylor) while eating . He doesn’t seem to be bothered by me . But he growls at my other dog our dog beds and toys . I can feed both dogs treats at the same time in vicinity of one another and have been trying to feed them both treats when they are near each other and have toys . My other Doug Taylor is a 13-year-old Doberman with mobility issues . I’m not sure if my new Greyhound senses his elderly-ness, or if the resource guarding is just because he feels insecure . I’m not sure how to handle Tres growling at Taylor.. from what I’ve read I shouldn’t necessarily be taking his toys away but just giving treats to him when he’s behaving how I want him to behave. I’m just concerned because he’s been especially growling today and Taylor has just been pacing the house looking for a place of refuge. Tres keeps trying to take Taylors bed and growls when Taylor comes near the bed or toys. There are literally six dog beds in my house for the dogs to lay in the entire basket of toys . Resources are not limited and Taylor is not trying to take Treaty from him. He will totally let me take the toy from him whether I give him a treat or not it’s just my other dog he has an issue with. I have had Tres in my house for 2 weeks. This is the first home he has lived in. Both dogs are baby gate separated when I leave. Thanks for any advice or things to try I see lots of resource guarding stuff in general but looking for dog on dog specific resource guarding with beds and space in addition to toys . This is my second Greyhound but I never had these issues with my first Greyhound. But this is my first race track Greyhound seems to be much different/difficult than just the stray Greyhound that I adopted.
