The dog can be anywhere, it always works to teleport it to you, even in unloaded chunks
There's currently a bug, where if the dog you want to call is too far away it will be invisible after the teleport
--> to fix that you have to rejoin the game
1. Tame a dog
2. Give the dog any name (it can not include special characters like # or ')
3. Hold any goat horn you want in your hand
4. Sneak and look at the dog for 4 seconds
4. You will then get a horn that looks enchanted and has the name of the dog
5. Whenever you use the horn, it will teleport to you
--> Only the owner of the dog can get the goat horn + use the goat horn to call the dog
