Hey! I just wanted to suggest adding some kind of optional feature to allow pets to teleport alongside you when you teleport, the main issue right now (and the one that has always been present in the game) is that when you teleport away it unloads the chunk you were just in, and since the pet is in that chunk it won't teleport to you.
It would really be ideal to have pets teleport alongside players by perhaps allowing the chunk around the pet to stay loaded at all times (perhaps when a specific item or enchantment is given to them? this would perhaps be configurable so that it wouldn't cause issues in servers?)
Thank you for reading, and sorry if Ii wasn't meant to open a github issue about this, but I had no idea how I could write this suggestion otherwise.

What kind of teleport? like a nether portal?

Ah no no, just like using the /teleport command to teleport to a waypoint or something of the sort.
The idea I had with keeping the chunk optionally always loaded around a pet was also because of the pets sometimes being left behind when flying/swimming, this way they could always teleport to you when you are back on land which would make adventuring with them far easier! :)
