I live on an acre of land, so even though I don’t have a fence, I make sure my pup is able to get outside often. I have plenty of toys to keep him enriched, and wouldn’t mind sharing his toys with others. In addition, I reward my dog for good behavior and would also do that for other’s dogs. He gets frequent potty breaks and is fed on a schedule. I would also make sure the same is done for any dogs I watch.
