PETA writes on their website:

PETA has been inundated with tips over the past two years alerting us to unethical and illegal activities in horse racing. This is why we now offer a whistleblower hotline for workers who have witnessed or know about cruelty to animals or other illegal activities involving horses used for racing or other equestrian competitions.”
“If you work at a racetrack, a horse training or breeding facility, a veterinary office, or any other business affiliated with or adjacent to the horse racing industry—whether you’re a vet tech, groom, exercise rider, hot walker, or a timer in morning training—you may have seen something that needs to be reported.”

“Your confidentiality is important to us” continues PETA. “Although you may choose to remain anonymous, we encourage you to let us know how we can follow up with you in case we need to clarify any details.”
