Canid identification: wolves, coyotes and dogs

To the untrained eye, it can be difficult - especially at a distance - to tell the difference between a wolf, coyote and domestic dog. In general, wolves are larger and bulkier while coyotes are shorter, sleek and lighter on their feet.

Wolf characteristics

The following wolf characteristics were designed to help non-biologists determine if an animal is wolf, dog, or hybrid. They are the average measurements taken from 24 adult wolves. Certain characteristics may vary with animal's age and health status, such as canine wear and fur conditions. If an animal has at least 8 out of 10 of these characteristics, there is a high likeliness that it is at least part or mostly wolf, but in some cases DNA testing may be needed to confirm its status.
