Tamed cats and dogs stop following/teleporting when I run

After taming a pet, I start running in one direction and loose them as they don't seem to teleport to me after a short distance of running. If I walk slowly they will follow.

If go back to them they are just standing where I left them (see screenshot).

I tried making a new survival game to test and the same thing happens with the cats and dogs.

Happened first in snapshot 14w25b and now as well on 26b.

I am on Win7.
