What specific tail fault is mentioned regarding shape when the American Bulldog tail is left natural?

Answer

Tails that are corkscrewed, kinked, or curl completely over the back when relaxed.

When assessing the natural tail of an American Bulldog, several characteristics define acceptable carriage versus faults. Ideally, the natural tail should be thick at the base, taper toward the tip, and reach down to the hock joint, usually carried in a 'pump handle' style. However, certain structural deviations in the tail vertebrae result in disqualifying faults. Specifically, tails that exhibit a corkscrew shape, possess kinks along their length, or curl completely over the back when the dog is in a relaxed state are considered faults that compromise the standard conformation of the breed's extremities.
