Crib and Rosa

Crib and Rosa is an 1817 painting by Samuel Raven, a follower of Abraham Cooper; Christie's attributes the painting to the latter, noting a variant held by the American Kennel Club.

The painting depicts Crib and Rosa, two well known Old English Bulldogs. Rosa was considered to represent correct formation for bulldogs at that time. Through John Scott's engraving, this painting became the best-known and most reproduced painting of dogs from that period. This painting provides an image of the extinct Old English Bulldog breed.

The image was frequently referred to by exhibitors as an ideal form of the breed. Writing at the end of the nineteenth century, Dalziel says any deficiencies in the otherwise perfect outline of Rosa was due to her sex; lacking desired characteristics of wrinkles and bone structure.
