Dog-lover, dog lover.

"A dog-lover is one who loves dogs; the dogs are the object of his love. James Thurber was a dog-lover. A dog lover, without the hyphen, is still a dog—the Tramp, say, in Lady and the Tramp.... A bird-watcher is a watcher of birds; a bird watcher would be a bird that keeps an eye on things. You can actually hear the difference (and feel the bird’s eye on you). This was brought home to me when a woman from California, one Alice Russell-Shapiro, wrote a letter to the editor—the copy editor—of The New Yorker complaining about (among other things) the term 'star fucker.' She was not the least offended by seeing the term in print, only by its lack of what she called the 'activating hyphen.'... In 'star fucker,' without the hyphen, each word has equal weight: a fucker who is a star. But in 'star-fucker' the hyphen tips the weight to the first element, the object (star) of the activity embodied in the noun (fucking)."

From Mary Norris, "Between You & Me: Confessions of a Comma Queen."

(And when you’re a star, they let you do it. You can do anything.)
