My tamed wolf on minecraft growls at me?

So heres the story:
I have Minecraft on my xbox 360 and I got a pet wolf. His name is Dogea and I thought he was lonely so I killed some skeletons and got another, her name is Fido. When I tamed her she was in a pack of 3 wolves and I had some bones left over so I tried to tame another but it went under a tree and when I tried to break the leaves I accidentally hit it and the 2 wolves started to attack me. Fido helped me kill them so I went home and I put Dogea and Fido in love mode and they had a little puppy who I named Winifred. Now, after they had a puppy, Fido keeps growling at me when I go near her. Maybe it's because she was near when hit the other wolf or maybe because that wolf used to be in her pack, but how do I get her to stop?
P.S. I already tried where I get untamed wolf to kill me but it didn't work.
