Cynodesmus is an extinct genus of canine. The 1 m (3 ft 4 in) long creature was one of the first canines to actually look like one. It probably looked like the modern coyote, but had a shorter skull, heavier tail and longer rump. Also, Cynodesmus was not a very good runner compared to most other canines; it probably attacked prey from an ambush. Like felines, it could (partially) retract its claws.
