The dog was Penny. The win was priceless. A Doberman pinscher named Penny won best in show Tuesday night at the Westminster Kennel Club Dog Show, netting US show dogs’ most coveted prize — and giving veteran Andy Linton another win after nearly four decades. Linton got best in show in 1989 with another Doberman, named Indy. Penny “is as great a Doberman as I have ever seen,” Linton told a supportive crowd. Despite ongoing health problems, he had guided the 4-year-old dog through a razor-crisp performance. “I had some goals, and this was one of them,” Linton said.
