Pasadena Digital History
The Henry H. Markham House at 703 S. Pasadena Avenue in Pasadena. Markham served as California governor from 1891-1895. The picture is dated circa 1890. This neighborhood is now known as the Markham Place Historic District, on the National Register of Historic Places. Ironically, the Markham House itself was demolished in 1939. There are some remnants left from the past, however:

The retaining wall and stone posts were part of the Markham estate. The posts apparently came some time after the first photo was taken, and the retaining wall seems to have been redone at some point, but if you look at the curve of the driveway, you can see that it's the same property. Apparently the carriage house still stands on the site. You can't see it from the Google view, so I might have to go down there and walk by sometime.
Looks like the pooch is letting us know how he feels about the demolition of the Markham House.
