It was five years ago, in almost exactly the same setting, among a throng of adoring dog owners and their lean, quiet animals, that Marita Pierce was smitten with greyhounds. She'd been married only a few months and was looking for a dog to join her cat, Jasper, now 13. No, Jasper had not been a bad cat. But Pierce, who'd owned a pair of Irish setters for many years, dearly wanted to enjoy a dog again. During Three Rivers Festival, she stopped by to speak with owners who'd adopted greyhounds once used at racetracks.
