Summary timeline: What's behind US Equestrian, American Horse Council calls for delay of USDA's new Walking horse soring regulations?

Readers in the USA may be aware that long-anticipated changes to the federal Horse Protection Act are scheduled to go into effect on February 1. These new rules change the way that Tennessee Walking horses will be inspected at horse shows, and by whom, in an effort to prevent deliberate "soring" practices to enhance gait.

If only it was that easy.

American Horse Council Statement on Nonspecific Language in USDA Horse Protection Act Amendment

For the past few months, the US Department of Agriculture has been hosting "listening sessions" around the country and gathering input about a proposed amendment to the American Horse Protection Act, which bans the "soring" abuse techniques used on some Tennessee Walking horses to gain an advantage in the show ring in some classes, particularly where the horse is asked to do the famous "big lick" walking gait. 

Among the features of this amendment is complete outlawing of pads, action devices such as pastern chains, and weighted shoes.
