The wolf had blue eyes and an angel halo. ONLY WHEN YOU TAME IT, WILL THIS TEXTURE PACK SHOW.
Instructions: (I highly recommend you copying the original wolf-tame.png file and saving it some where you can find it easily)

- Go to your .minecraft folder (you can locate it by typing %appdata% in the address bar).

-Aftern you're in your .minecraft folder, open your "bin" folder. Then locate your "minecraft" section and open it with 7-zip or anything that will open you to its archives.

-Then scroll down to the folder "mob" nand open it. Find "wolf-tame.png" and delete it, then replace it with this wolf-tame.png I'm sending you (located in the "mob" folder in the download). n(this is why I highly recommend you copy the original "wolf-tame.png", so you ncan put it back to normal if you want.)

If you have ANY problems, just let me know and I'll help anyway I can :)
