A friend of last weekend's out of control Boston Terrier that left Dolores Park shattered fills us in on the dog's personality:

I work with this dog at Murder, Inc. He is the cold-bloodedest killer of all my colleagues. His name Falkor. Like from The Neverending Story, but the story he will tell trick bitches on his turf is The Neverending Critical Beatdown. Ferocious.

Also, Re: the headline, let me assure you he was in complete control the whole time and if he appeared out of control, it is because that's what he wanted you to think. Falkor specialize in psychologistical mind freaking.

Somebody better call animal control.
