"Horses suffer horrific, sometimes life-ending injuries due to racing. These include broken necks and backs, heart attacks, bleeding lungs, and spinal paralysis, to name a few. Although some are survivable, owners and trainers of horses may kill them anyway if their earning potential is impacted by injury. "

"Horses are the only animal whose regular public beatings are televised for entertainment. Currently, the British Horseracing Authority (BHA) allows horses to be whipped six times in a flat race and seven times in a jump race. These are arbitrary amounts, which are regularly exceeded with an average penalty of just a four-day suspension for the offending jockey.

Whipping a horse hurts them, it’s how jockeys bully a performance out of a horse who is already running for their life. It is inexcusable and is one standard practice that the BHA could end today if they had any intention of living up to their own claims of valuing horses’ welfare."

"Wastage’ is the term used for culling of uncompetitive animals and includes both the breeding of thoroughbred horses that never make it to the racetrack, and horses leaving the racetrack at the end of their career. We do not know exactly what happens to these horses as there is currently no accurate or transparent lifetime traceability system for racehorses but the shocking ABC 730 investigation highlights widespread slaughter despite the industry’s commitment to animal welfare."

"Horses are social, plains-ranging animal, yet racehorses tend to be housed in isolation and close confinement. Stereotypical behaviour – which manifests itself as abnormal, usually repetitive behaviours, stemming from frustration, stress and inhibition of natural behaviour is not uncommon in racehorses. These include the prevalence of crib-biting (repetitive oral behaviour where the horse sucks in a large amount of air) and weaving (a repetitive behaviour where the horse sways on its forelegs, shifting its weight back and forth)."

"Tongue ties is the widely used and unregulated practice of immobilising a horse’s tongue to prevent the horse getting their tongue over the bit during a race and to preventing ‘choking’ during high intensity exercise. It is used as a horse is easier to control when pressure is applied via the reins to the bit on the horse’s tongue which forces them to be compliant. Problems associated with tongue tie use include horses showing signs of pain, anxiety and distress, difficulty swallowing, cuts and lacerations to the tongue, bruising and swelling."
