Tamed Wolf wander option

(I'll refer to tamed wolfs as dogs in the rest of this text.) It can be quite boring having your dog follow you everywhere in Minecraft. Also, many players constantly check if their dog gets lost, it's always a worry for me. On the other hand, having them sitting down all the time fills some of us with guilt. Yeah, it's not a real dog, but still, it's cruel to have that creature sit there all the time. Those are the reasons I don't have any dogs in my Minecraft worlds. What I'd like very much would be if I could have my dog walking around my house, having some fun and attacking possible hostile mobs. Always staying in that general area. So, this improved dog would have three settings: follow, wander, and sit. In this new wander setting, the dog would pathfind on its own, but would always stay within, for example, 200 blocks circular in relation to the location where it was set to "wander". In addition, a craftable item could be added, a "Dog whistle", which could be used to bring a dog that is wandering in a far away area back to the player. Maybe the whistle could be paired with a single dog, or it would work with all dogs. Either would be nice. I think this would be a very useful addition to Minecraft and that it would encourage many more players to have their own dogs in this wonderful game.
