Canines are a group of carnivorous mammals, usually sharing the common physical traits of triangular ears, a long, tapered snout, and a somewhat bushy tail. Although their habitats range from arctic wilderness to your own back yard, canines are primarily social animals, with most living in close-knit family groups (packs) throughout their whole lives. They are typically vocal animals, using any variety of whines, growls and barks to communicate, as well as physical posturing to express everything from excitement to submission.
