What are the author's feelings about graveyard?

The narrator remarks that the Duchess' dog's deserve tombstones as much as the average Christian. 

She had a special graveyard made, in which to bury them when they died, and there they lie, about fifty of them, with a tombstone over each, and an epitaph inscribed thereon.

Well, I dare say they deserve it quite as much as the average Christian does.
