@MicheleV_AK Amazing "sport". Another dog died (the 154th), many had to be abandoned due to exhaustion, many have wounds. One set of dogs got pneumonia another kennel cough.
One dog was forced to race despite having medical issues another was forced to race with wounds on its scrotum.
As for long term many dogs have to be given regular medication to combat exercise induced gastritis. Many get myopathy and enlarged hearts.
Most live miserable lives chained in their "yard" when not racing. Raids by authorities have shown many live in dirty squalid conditions.
As for Holmes - well he is apparently well known for forcing his dogs in training to pull a heavy metal cart through freezing cold water.
What a "sport" indeed.
