It is now version 0.9.0. In this update there are wolves, villagers, silverfish, slime, all types of flowers, different biomes, vines, all types of eggs on creative, monster spawners, mooshrooms, Enderman, caves, lilly pads, colored clay, abandoned mineshafts, emeralds and loads more!
To find wolves, look in caves and dark areas. They like to hide in the dark. I really love how they shake of water when they are wet!
I hope this is helpful.
