Not 100% sure, but it's in the spirit of the walnut chair with carved dog's-head arms made by Joseph Zangerle & Co., Chicago (H 39 1/2 in., W 29 1/4 in., D 22 3/4 in.) . See Sharon Darling, "Chicago Furniture: Art, Craft, & Industry, 1833-1983" (1984), 75-76. According to Darling, "Obviously popular in its day, Zangerle's "Dog Head Chair" and its numerous variations are among the few easily identifiable examples of Chicago-made seating furniture commonly found in the Midwest today." I believe that the Winterthur Museum also has a Zangerle catalogue from the 1880s, and that might be worth tracking down.
Wonderful book. I believe the chair I have is the high grade dog arm chair that Zangerle produced. I've glued it up, cleaned and over coated walnut and my upholsterer has it retufted in muslin awaiting buyer's choice of final upholstery.
