This victory marks veteran handler Andy Linton's second Best in Show win, almost four decades after his first triumph with another Doberman in 1989.
Linton, who is nearing retirement, described Penny as "as great a Doberman as I have ever seen," making the win at the 150th annual show particularly significant for him.
The runner-up was Cota, a Chesapeake Bay retriever, with other finalists including an Afghan hound, Lhasa apso, Maltese, Old English sheepdog, and Smooth Fox Terrier.
Penny emerged victorious from a field of 2,500 dogs representing over 200 breeds, with the event also highlighting other memorable competitors, such as Millie, a Danish-Swedish farmdog making history in the semi-finals.
