If you follow the world of organic and vegan pet food as breathlessly as we do, know that Bocce’s Biscuit Bike, that doggie food cart we told you about a while back, is now rolling. The three-wheeled dog-treat vendor roams city parks Fridays through Sundays (it’ll be at Central Park this weekend), dispensing biscuits in flavors like all-natural chicken cordon bleu to hungry pups, and … this just in, doggie ice cream! For the record, that consists of "Organic yogurt, organic peanut butter swirl, fresh bananas, a bit of honey, and bits of our PBnJ doggie biscuits," writes founder Andrea Tovar. "It really looks like a cookies & cream — but for dogs." Follow the Bocce’s Bakery Facebook and Twitter for Biscuit Bike location updates.
