In comparison to my Lego Duplo doggy ideas, I tried to make wolf look meaner. Therefore I decided for an open mouth with evident gnashers. This was accomplished with stacking 2 long, narrow and thin bricks on top of each other in a slight mismatch-way. This way we get a thin tail on one side and an open mouth on the other. head is made out of two bricks. Bottom one represents the upper jaw, while the upper one replicates top of the skull and ears.
The build itself pretty much covers a nice minimalistic silhouette, one that would look even more awesome if you use some wolf-like colors.
