From the Gothamist, a disturbing video of a dog killing a rat in Washington Square Park--one of the dog's 10-15 victims. This happened at night, so if the dog had an owner, the dog was off-leash illegally. Hat-tip to Christina.
And from the Daisy Parker blog, a photograph of a dog squatting in a playground, post like this is some sort of joke. Hat-tip to Winston.
