That is author Stephen Kellogg with his dog Pinkerton, who inspired a series of children's books.
I can see the Dog in Doctor Faustus Lights the Lights WANTING to be as cool as Pinkerton. He WANTS to misbehave and be loved for it. He WANTS to be able to hang out and flop around and do his own thing. But he can't; he can't bay at the moon at his own free will like that (not that a Great Dane bays at the moon, but still...).
Another reference: Read one of my favorite book's from when I was a kid -- Agatha's Feather Bed by Carmen Agra Deedy. Unlike the Pinkerton series, which I just find cute, Agatha is a reflective grown-up tale. The geese in it, who appeal to Agatha because they are cold after she buys a goose feather bed, remind me a LOT of the haunting figments inhabiting Goodhart.
