Add some kind of sheepdog

It is currently very tedious to keep together animals, by either using leads, which break easily, or their favorite food, but many animals have different favorites. It would be cool if you could use dogs to keep large hordes of different animals together. This could be activated like a "sheepdog mode" like sitting, by right-clicking with a specific item, maybe a wheat bundle or a "sheepdog outfit", similar how real-world searching dogs have a special harness to tell them they are on duty. This would be best as an early-game item and therefore craftable. The sheepdog would then shoo animals like sheep, cows, chicken and maybe bunnies towards you. It would also be faster and/or more precise if you use multiple dogs (I have like 15 on a realm that would then finally be useful). Maybe sheepdogs could also spawn near village barns. I have no theme for a potential update this could fit in, because it fits almost anywhere, as a cave update is not to be expected.

This would make life easier in early game, where you don't have giant autonomous farms, but small barns that sometimes are blown up by creepers.
