Wolves act oddly

wolves have their dyed collars and will sit/stand when made to, but look untamed, growling if after something (even when aggravated while sitting). they will attack anything that i hit last nomatter if they were sitting. occasionally, tails glitch up&down. other times, they will become aggravated when i am attacked but they are too far away, and when i come back they are standing, will not move, and i must hit them so that they will move and be able to make them sit. i am on a PC with windows 7.
