Local street artist fnnch (pronounced like the bird) has just committed one of his "random acts of art" in Duboce Park, adding fun dog stencils — including the Jeff Koons tribute above — to the existing, city-made sidewalk-marking stencils indicating on-leash areas for dogs.

Both Curbed and Hoodline point out the stencils and many people have already been Instagramming and tweeting them, in the last 24 hours.

Of course there is also an origami corgi.

And a pug on a skateboard.

And more.

You can see more of fnnch's art around town, like in the Bayview, where he's been painting ladybugs on the sidewalk.

Or these sea turtles.

Or this honey bear on Divisadero.

Or his variations on the bear, like the Star Wars bear, the Magritte bear, and the Bowie bear, on mailboxes around town.
