Tamed wolves attack when a wild wolf is hurt.

When wild wolves are attacked, any other wild wolf plus that one targets the attacker. Well this happens with tamed wolves. If something attacks a tame wolf, any tame wolf with the same owner will attack it. Well, what if something attacks a wild wolf with only tamed ones around? Well, the tamed wolves attack!

What I expected to happen was...:
When a wild wolf is attacked, the tamed one does not chip in.

What actually happened was...:
The tame wolf did actually attack.

Steps to Reproduce:
1. summon a snow golem and make it accidentally attack the wild wolf.
2. Have a tamed wolf near by
3. the tamed wolf will come attack the snowman even though it hit the wild one.
