This is what an evil pit bull looks like (not):

This is Calvin. A couple of months ago, his mom Gerri rescued him from Liberty Humane Society in Jersey City. Gerri says Calvin was covered in mange, and was "the sickest dog there."

Not now. Last night, when they met Calvin and Mavis did a beautiful dance of submission (one guy I know calls it "a submit off") where they sniffed, lolled around, and began again. Calvin's no puppy--maybe 4 or 5. But he is ready to greet the day, every day.
