After breeding two tamed wolfs and ordering the new baby wolf to sit, the baby wolf stands up for a brief moment, causing it to teleport to the player if there is room, regardless of how far that player is. Wolfs will not teleport if the player is inaccessible or in another dimension, as per usual, but will teleport upwards of 1000+ blocks to sit down at the players feet.

Attached video is in version 1.13.2, showing this behavior over a short distance.
