You celebrate your dog’s birthday with cake and party hats. Yes, you’re that kind of dog owner. But there’s a good chance the slice of heaven you’re feeding Fido could be dangerous to his health. Instead, bake him a cake with Puppy Cake, the cake mix and frosting meant for dogs. Flavors include banana, carob and peanut butter, and are 100% safe to serve to your four-legged friend. They’re yummy enough that you might be tempted to try it yourself, but don’t worry; we won’t tell anyone if you lick the bowl ($6.99, puppycake.com).
