A way to control tamed wolves more. The dog whistle!

When i play Minecraft i always love breeding a horde of dogs and kill everything with them. we all know that one guy on the Minecraft server. Sometimes when having tons of wolves they can get in the way. When you are building they walk in front of you, when you are walking around they fall and your friend accidently hits you and your dogs are killing him. you have so many dogs that its a pain to have to sit all of them one by one and stand them up one by one. sometimes you don't want millions of dogs walking with you but you are too lazy to sit them all. That is where the new feature i want to get added to come in. Say we have a sort of dog whistle. when you use it when crouching all your tamed wolves will sit automatically and if you use it while standing normally it would stand up all your dogs and make them gather around to you for a little bit as long as you are holding it. this will also remove any aggression the dogs have. Your friend hits you and your dog is killing them? use the dog whistle and they are calm! are your dogs chasing a skeleton into lava? use the whistle to stop them! done exploring and want to sit all your dogs? just use the dog whistle while crouching and they will all sit. The fact that they gather around you will help keep them out of danger and make giving your dogs splash potion effects easier. This feature will be so cool especially for players like me who love dogs and make dogs much more fun and easy to control.
