The Golden Retriever is a medium-large gun dog that was bred to retrieve shot waterfowl, such as ducks and upland game birds, during hunting and shooting parties. The name 'retriever' refers to the breed's ability to retrieve shot game undamaged due to their soft mouth. The eyes are round and dark, which is in contrast to the triangular or slanted composition of their American counterparts. British Golden Retrievers can have a coat colour of any shade of gold or cream; red or mahogany are not permitted. Originally, cream was an unacceptable colour in the UK standard, but the standard was revised in 1936 to include cream.
