Wolves have big difficulties attacking large Slimes and Magma Cubes and Horses

this is a bug and we need to fix it :d just saying

I think it is intended that wolves can't kill medium and large slimes.

Can reproduce, though for me this only occurred with large slimes.

Added horses.

Is this still a concern in the current Minecraft version 1.6.4 / Launcher version 1.2.5 ? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Cannot Reproduce Fixed
Might have been Fixed. During my tests, only very small complications with the big slimes were encountered, but all in all, it's fine now.
