A video released by the U.S. Department of Agriculture shows the dangerous results of a practice known as soring on horses.

The AVMA says that soring is “the harmful act of intentionally inflicting pain on Tennessee Walking Horses and other gaited breeds through the use of chemical and physical means, such as hard acrylic wedged in between a horse’s shoe pads and sole, the application irritants like kerosene or cinnamon oil, or overly tight metal hoof bands.”

Veterinarian assistants work with a variety of animals, including horses, which can be victims of painful practices like soring.

“This USDA video underscores the concern that the cruel and illegal practice of soring is still a big problem in the walking horse industry. This is why the AVMA fully supports passage of the PAST Act,” Ron DeHaven, CEO of the American Veterinary Medical Association (AVMA), said in a press release. “Despite the fact that soring has been illegal for more than 40 years under the Horse Protection Act, we are still seeing these inhumane practices inflicted on the nation’s walking horses. This new USDA video footage illustrates the need for the PAST Act to strengthen the USDA’s ability to prevent soring and the resulting suffering of the horses who are victims of this practice.”

Veterinarian professionals work to treat animals who are the victims of painful practices, but they are also on the frontline in helping to spot the symptoms of these types of problems, such as soring with horses.
