I did extensive research for the Saint Roch post on the November 1. So I was surprised to find another portrait of Saint Roch by Giovanni Battista Tiepolo at the Philadelphia Museum of Art. While I don't consider this a great work of dog art, I think it is interesting as a Tiepolo, a Venetian artist famous for his dramatic Baroque style. And the disembodied head of the dog speaks to composition challenges all dog artists face.
The Philadelphia Museum of Art has an excellent website that makes searching a pleasure, not always the case with art institutions. Click here to view their collections.
