Ch. Shargleam Blackcap, (born 26 June 1977), also known as Brett is a Flat-Coated Retriever show dog bred and handled by Mrs Pat Chapman who won Best in Show at Crufts in 1980. He is one of the ancestors of 2011 Crufts Best in Show Sh Ch. Vbos The Kentuckian.

In 1980, Brett became the first Flat-Coated Retriever to win Best in Show at Crufts. Reserve Best in Show went to the previous year's winner, the Kerry Blue Terrier Ch. Callaghan of Leander. He was the most successful showdog of his breed in his era, and became a successful sire. His descendants include 2011 Crufts Best in Show, Sh Ch. Vbos The Kentuckian, and was the last Flat-Coated Retriever to win a Best in Show in a multi-breed show until The Kentuckian at the East of England show in 2009.
