I currently work in a nursing home and know first hand how much the residents LOVE dogs to come in. Most of their four legged friends come in with a resident's family member but we do have a few people that bring their dogs in every month or so just to visit. You wouldn't believe how a shy, timid person reacts with dogs but not with people. It brightens everyone's day. I have yet to bring Oscar in because I believe he is way too hyper. He can't even handle people coming to his own house...non the less, going to someone else's. The last home I worked in had two resident cats and a small dog which I believe was a yorkie or something of the sort. I have not seen a boxer visit but I think that's because they are scarce in my area. But I've seen St. Bernard's all the way down to toy poodles. I think as long as the dog is trained to listen to your commands they are ready to enter the homes. I also believe that dogs have a sense for people. They just "know" that someone is frail and weak and not physically able to "PLAY". Good luck, I know the residents will love you!
