Tamed Foxes and how they could work.

When you breed 2 Wild Foxes together, you can take the baby away and when it grows up you get what I like to call a "Trusting Fox". It won't runaway from you, but it won't follow you. It's just there, minding its own business

If you breed 2 Trusting Foxes and take the baby away, you get a Tamed Fox. The Tamed fox can sit and stand at the player's command and it will either sit or sleep depending on the time of day. It will also sleep on the player's bed during the day. It will also follow the player, like normal.

Tamed Foxes won't attack Rabbits or Chickens and they maybe won't be attacked by Wolves? If they do, they will either fight back, or hide behind the player.

Maybe they could even act like the Allay, picking up and bringing whatever item is in its mouth to the player. Or they could just give the player random items like a Cat does.
