Wolves in mutiplayer that where spawned in w/ wolf spawn egg turn untamed after being hit. Also they turn the dye color that you tried to dye their collar with

I was playing on a multiplayer server on creative and decided to get a pet wolf. I spawned one in and tamed it. I switched to cyan dye to dye his collar. It kept giving me the stand/sit button. I decided the wolf would be a pain to have around when trying to build so I hit it with my diamond sword. It became a untamed angry wolf that was cyan in color.

I am using a Nokia Lumia 521

What I expected to happen:
My wolf takes damage

What actually happened was:
My wolf became a untamed angry cyan colored wolf

Steps to reproduce
1. Join a multiplayer creative server
2. Spawn in a wolf with wolf spawn egg
3. Tame wolf
4. Try to dye it with cyan dye
5. Hit wolf with a diamond sword
