Dog Whistle and Clan System

Would you be able to implement a dog whistle in the next update? it would be really useful for sitting all of your dogs down at any given moment if your friends accidentally hit them, that way they won't come charging at them. The whistle could also be used to make all dogs stand up instead of having to individually make them stand up one by one, it really saves time and effort. Another thing I would like to discuss is a clan system for the next update. You can assign your friends to your very same clan and that would give you the option to ether disable pvp between yourselves or re-enable it. I think this would be a really cool addition, an it would also address the dog problem as well, as if you disable pvp, your attacks will have no effect on you friends/clan members, and so your dogs won't be attacking them.
