Portrait of a Large Dog

Portrait of a Large Dog is an oil painting by George Stubbs. Depicting a dingo, it is the first depiction of an Australian animal in Western art, along with a painting of a kangaroo by Stubbs. It is part of the collection of the National Maritime Museum in Greenwich, London.

The work was commissioned by Joseph Banks based on his observations of dingoes on the east coast of Australia in 1770 during Lieutenant James Cook's first voyage of discovery. No specimen was collected for use as a subject, unlike its companion painting The Kongouro from New Holland, and it is seen as a fairly general depiction of a dingo, soon superseded by a more accurate one in 1789. The two were the only two paintings that Stubbs did not draw from a live subject.

It was first exhibited by the Society of Artists in London in 1773 together with his painting of a kangaroo, The Kongouro from New Holland. The painting has been on view in recent years at Parham House during public openings.

In 2012, Portrait of a Large Dog and The Kongouro from New Holland were purchased together at auction for 9.3 million Australian dollars by an undisclosed buyer. An application to take them to Australia was refused by the Department of Culture on the grounds of their national importance. Sir David Attenborough, who had led a campaign to keep both portraits in Britain remarked that it was "exciting news that these two pictures, so important in the history of zoological discovery, are to remain where they were commissioned and painted". The National Gallery of Australia had expressed a strong desire to purchase the portraits. In November 2013 it was announced that a £1.5million donation from the Eyal Ofer Family Foundation will enable the National Maritime Museum in Greenwich, London to acquire the two paintings.
