Tamed Wolves will not teleport to the owner

After taming 3 wolves on a server, I was walking across the land and when I was getting attacked by a skeleton, my wolves were still far away.
Eventually, I had to go and find them and walk to the same place AGAIN, just because my "dogs" didn't teleport to me, like they did in earlier versions (ex. 1.6 - 1.7)
