l can think of a few winning race horses with crooked legs. And one breeding stallion with a parrot mouth. and wasnt there a horse in the kentucky or another major race that snapped a foreleg due to the bone being so fine. There was an article about it in one of the newspapers. A well known elderly TB breeder was searching for well boned old fashioned mares to put some bone back into his TB stud. His search took him to Russia and South America He felt with all the line breeding TBs were getting too fine l love flashy coloured racehorses, fav is starspangledbanner.
