I'm a bad dog! What kind of a dog are you?

I'm a bad dog! What kind of a dog are you? (this is the actual title of the work) By C. M. Coolidge, created in 1885 as a hand-colored photogravure.

Head-and-shoulders of a Boston terrier(?) with a bloody face. I guess there was a different view of cruelty to animals back in the 19th century.
