Your tamed wolf will attack your tamed parrot

I accidentally attacked a tamed parrot that I owned, and my tamed wolf killed it. I assume that this is a bug, as dogs do not normally attack animals that belong to you.

For example, they wont attack a dog or cat you own, but they will attack a dog or cat someone else owns.

Steps to Reproduce:
1. Tame both a wolf and a parrot
2. Attack your parrot. Your wolf should try to kill it.
3. Now tame a cat or another wolf. Attack it. The original wolf shouldn't react at all.
