Belgian painter, trained at the Academy of Courtrai and student of Ed. Woutermaertens (1848-1852).
He specialized in animal painting and more precisely in scenes with dogs and/or monkeys.
His time in Italy, where he learned landscape, marked his painting. In his studio, he had a menagerie of monkeys, wolves, foxes, to better paint them.
If we find dogs hunting, monkeys in sumptuous interiors, where de Vos is the best, it is in the representation of street dogs. His work was commercially successful and was exhibited mainly in Belgium and France. He is one of the main Belgian painters with Noterman in this kind of representation.
