This cartoon for a tapestry intended to hang over a door shows two boys with two large muzzled mastiffs. It is paired with Boy riding a Ram, another over-door tapestry cartoon, now at the Art Institute of Chicago.

This work was conceived by Goya as part of a series of tapestry cartoons commissioned by the Royal Tapestry Factory of Santa Bárbara in 1786. The resulting tapestries, based on the Four Seasons, were to be hung in the Prince's dining room at the El Pardo Palace. Due to the death of King Carlos III (1716-1788), they never reached their original destination, and were used instead to decorate various rooms at the Monastary of El Escorial, with no specific order.
