Well, I'm not a dog racing fan specifically, but an animal lover - sure. I have a couch potato of my own, the veteran of 3 wins in 96 starts, and who has an amazing ability to get inside parcels of anything edible within reach of the long nose.
The noble Thoroughbred does it for me, a more courageous, generous and talented athlete would be hard to find..IMO.
But thank God for the likes of Yankiwi, who, with his experience in several jurisdictions, can find specific reasons for the attrition rate - and actually gives a sh#t.
