Tamed wolves won't move, only teleport and won't attack mobs hit by the player

I tamed 2 wild wolves and their AI still seemed to be working fine. After a little bit, I noticed they didn't follow me, but only teleported to me when I got far enough. I tried to tame another 2 wolves after that and they all got the same issue. I tried to make them attack a spider (as the video below) but they refused to do so.
