If horses don’t die on the track, they often die another way. When horses can't race anymore or no longer become profitable, they're "retired," but this doesn't mean they spend the rest of their days grazing and sunbathing. Instead, retired racehorses are usually sent to slaughterhouses, and their meat is then used for dog food in Australia, or it’s sent to countries like Belgium or France for human consumption.
Over 25,000 Australian horses are killed in slaughterhouses each year, and the majority of those horses were race horses, according to Animals Australia. What’s more, the killing process is quite horrific for the animals — horses usually have to watch their friends and family members die while they wait to be killed themselves.
