I accidently hit my wolf when we were out exploring. I killed some animals from my farm to heal him. When I gave him the food he ate the food, but his health did not rise. His tail did not go up and heart animations did not appear.

I am on Nokia Lumia 521 with Windows Phone 8.1, since there was not a option for my device

What I expected to happen:
My wolf's health to go up

What actually happened was:
My wolf took the raw beef/ raw porkchop/ raw chicken, with out gaining health

Steps to Reproduce
1. Tame a wolf
2. Hit the wolf with anything
3. Feed the wolf with any of the raw meats
