Veterinarian Amy Dixon thought she was just helping out at the county dog show. Instead, she ends up in a dog-eat-dog world of rival breeders, pampered pooches, and one very dead Chihuahua breeder. All Amy wanted was a quiet day filling in for a sick colleague. What she got was a snarling confrontation with Mildred Blankenship, the queen of the Chihuahua circuit-followed by a front-row seat to a growing list of people who'd be just fine if Mildred took her last lap around the show ring. Then Mildred drops dead, and it turns out someone wasn't bluffing. With Amy suddenly in the doghouse as a murder suspect, she teams up with charming snack-stand guy Nick Wyman to sniff out the real killer. But as they dig into the tangled leashes of show dog drama, they realize this mystery has more twists than a poodle's perm. Will Amy and Nick find the culprit before someone else gets collared-or are they about to be the next ones put down?
