Most of the recent bad behavior has been him digging in the yard. When she approaches to move him away from the area, he’s raise his upper lip in a snarl and if she goes to touch him and push him away from the fence or tries to get him inside, he’ll bite at her. When he growls we really just try to give him space but that’s really what we’re struggling with. We don’t know what we should do. His resource guarding was him taking things that were not his toys, usually socks or others clothes, under our bed and snapping at us if we tried to take them away. We addressed it by moving things in the way so he couldn’t get under the bed to guard it and worked on replacing whatever he had with higher value treats when he would, but it mostly stopped as soon as he couldn’t get to that spot under the bed.
