Previously unseen dog painting by Manet to be sold at Paris auction

Artist painted pet as present for Marguerite Lathuille, whose family has owned picture for last 140 years

A previously unseen painting of a pet dog by Edouard Manet will be sold for the first time at an auction in Paris next month.

The French modernist artist dashed off the small work in 1879 as a present for Marguerite Lathuille, the daughter of a Paris innkeeper whose portrait he painted around the same time.
