Rebecca Cross with the Scottish Terrier, "Knopa" (McVan's to Russia With Love), bred in US, with Russian ownership, from the Terrier Group, and winner of the Best in Show category, celebrate with their trophy at the Crufts Dog Show in Birmingham, in central England on March 8, 2015. Crufts is one of the largest dog events in the the world, with thousands of dogs competing for the coveted title of 'Best in Show'. Founded in 1891 by the late Charles Cruft, today the four-day show attracts entrants from around the world. Growing competition from foreign-owned dogs has sparked concern that not everyone may be playing fair at Crufts, a British institution since Victorian times now billed as the world's biggest canine show. Owners of a prize-winning Irish Setter who died after competing at the renowned Crufts dog show claimed on Sunday their dog had been poisoned at the English event.
