He spent two or three years working in an office and the merchant who found sketches and drawings instead of figures in the ledgers gave him a commission to make a portrait of his wife.

He worked for some time under one of the greatest Dutch animal painters, Jan van Essen, and copied many of the old masters, such as Pieter de Hooch and Frans Hals.

He painted many small pictures of the life of the country people, of the homes of the peasants, with the light shining through the ancient windows.

On the Continent his pictures attracted much attention, and he was well received in the Netherlands, where his popular scenes were exhibited and sold at many provincial and National galleries.

De Hoog's work was included in the 1939 exhibition and sale Onze Kunst van Heden (Our Art of Today) at the Rijksmuseum in Amsterdam.
