Dogs Act Like Untamed Wolves

SUMMARY:
My dogs won't sit, wander around without teleporting to me, and in general just act like wolves. Their collars disappeared and their tails are drooping like they're injured, but otherwise, their textures have mostly stayed the same (white spots around their eyes like normal dogs). I tried to 're-tame' them with bones, but nothing happened. I also can't feed them.

I tried restarting both the game and my Xbox, but neither had any effect.
