"...greyhounds who do make it to the track are put at significant risk of sustaining serious injuries, such as broken hocks or legs, or head trauma, during training and racing. Up to 200 dogs are reported injured during official races each week. Some even die from cardiac arrest due to the extreme physical intensity of racing. On many occasions the injuries are 'uneconomical' to treat and the owner will instead have the dog killed. On average around 5 dogs are killed at official races each week as a result of greyhound racing." - animalsaustralia.org/issues/greyhound-racing.php 📷: Greyhound racing.
