Pet teleporter to increase their uses

A item that links tamed creatures that can be summoned on command to you and then when deactivated would go back to its starting point. This would give a use to mount mobs as you need them when you need them, gets rid of their annoyances like high hills, being left where they were and having to accommodate to them. There were plenty of times i have ridden a horse, seen a cave and had to leave the horse there only to have to treck back and find it after. Most of the time having a horse does not feel fun in minecraft and also gives it a use late game. Same with wolves it isnt fun taking them out, constantly checking behind you to see if their still following or if their just lost forever you can now just pull them out at the start of your combat, say you are going to a trial chamber taking a dog all the way down is a pain when you could just press a button and boom their there especially with the armour added. After using the nautilus this feature would make it alot more viable as once a ocean is fully looted it has virtually no use and is incredibly annoying to manouver around to the next one. Were given armour for them yet they can barely be used without alot of timw wasted transferring them and discomfort. This should be a later game item possibly found in the end (end update?) Cuz of the whole teleporting thing
