This error has been present for a long time and now I finally posted it)
Any pets (parrots, dogs, cats) will not be transported to the player if the player or pet is in the water.
This is especially annoying when you want to cross the ocean together with your dogs😛

Pets ignore teleporting to certain blocks (water, lava, magma block, and others), but they aren't set to ignore sea grass or kelp. This means that swimming to the bottom of an ocean will likely bring your pet with you, drowning them in the process.

I saw this happening on our Xbox realm with some dogs that I tamed. Lost a bunch of them in the ocean crossing.
