I've come across a few claims that porkchops, when held in your hand, allow you to 'lure' untamed wolves. I assume this means that they are more likely to spawn, or will come towards you if they have already spawned near you. Is there any truth in this?
I tried holding a pork chop for a while in an appropriate area, nothing spawned. Then I hunted down some wolves and stood at various distances while holding a pork chop, they didn't seem interested at all. Pork chops do not seem to have any effect on untamed wolves.
Bonus: bones don't do anything either.
