Wolves no longer teleport to player (or follow after a distance)

What I expected to happen was...:
After walking 10-20 blocks away from my tamed wolves, they would teleport to me.

What actually happened was...:
After putting about 10-15 blocks distance between me and my tamed wolves, they would just stand still and no longer follow me anymore.

Steps to Reproduce:
1. Tame a wolf
2. Run away from the wolf
3. The Wolf will not teleport to you and will stand still after a small distance
