@cphill If you see the other dog is a distraction in the other room, yeah bring them in and try. I had a pup that was really focused on where the owner is so I brought the owner in to sit beside me and we practiced that way cause I couldn't get them to focus on me at all.
@cphill What kinds of treats are you using? High value treats? With that energy, you would need to start small and reward heavily. A look at me and yes! Then expand on that. Start small and easy first (treats on the floor, "go find it! Yes!"). You will have to set him up for success. Success...
