Wolves living in the far north tend to be larger than those living further south. The wolf has a long muzzle, short ears, long legs, and a long bushy tail. Wolves have fur made up of two layers.

The top layer is resistant to dirt, and the under-layer is water resistant. The color of their fur can be any combination of grey, white, taupe, brown, and black. Wolves live in groups called “packs”. The members of the pack are usually family members, often just the parents and offspring.
