After five years of working at a bakery for people, Jennifer Mello realized that the best part of her job was meeting her customers’ dogs. So she opened Spotted Dog Bakery (spotteddogbakery.com), where she could make and ship treats for canines instead. Some of her best sellers are treats that look just like something a person would eat, such as a slice of pizza or these campfire s’mores. “I find it hilarious when it looks like a dog is having human food,” Jennifer says. These s’mores are made with only canine-safe ingredients, including carob instead of chocolate and a sugar-free marshmallow filling.
