Crufts dog show officials are checking reports that a dog who was set to win a prize was drugged by oponents.
Kerri the Doberman was tipped to win her category, but she became sluggish before she went into the show ring. Her owners think she was fed drugged meat.
Cruft's vet, Trevor Turner, said: "She showed signs of sedation."
Kerri's owners, Clive and Nancy Evans, have won the Best of Breed category twice, and say: "Someone is trying to knock us off the top of the ladder."
