Limber tail syndrome, or acute caudal myopathy, is a disorder of the muscles in the tail, usually affecting working dogs.
An injury occurring mostly in sporting or working dogs such as English Pointers, English Setters, Foxhounds, Beagles, and Labrador Retrievers. Limber Tail Syndrome is also known as Cold Water Tail, Broken Tail, Dead Tail or Broken Wag.
Typically the presentation is a young adult dog with an acutely flaccid tail that hangs down from the tail base or is held horizontally for 3-4 inches and then drops down. The tail remains in this position even when the dog moves about. Pain may be seen on touching the tail base and some owners report that the dog seems uncomfortable. The best thing to do is leave the tail alone.
