Tongue tied? One in five Australian race-horses are

The use of widespread use of tongue-ties in horse racing in Australia has come under fire.
Proponents of the tongue-tie – a strap that immobilises a horse’s tongue – argue that it prevents breathing issues during races, increasing performance and improves the rider’s control of the horse.
But there is limited data to show that tongue-ties improve racing speeds overall, and there’s mounting evidence that they can cause stress and injury. Tongue-ties are banned in most non-racing equestrian sports in Australia, and Germany recently banned them altogether.
