Treeing curs are small or medium-sized dogs known for their speed and agility in rough terrain. The body should be slightly longer than the tail, however the tail is frequently naturally bobbed or artificially docked. The ears should be natural and floppy, not erect. The dog should have long legs and a smooth gait. The coat should be dense and close, and all colors except albinos are acceptable. The dog is built for stamina and should look like a working dog - in the United Kennel Club standard, scars are not penalized, nor used as a mark of a dog's working ability.
