This recipe makes enough for a 2 layer 8-inch cake or a 3 layer 6-inch cake, as shown here. Cut the recipe in half for smaller party pups, or make into pupcakes. Although this recipe contains all ingredients considered safe for dogs, we always encourage you to ask your veterinarian if you have concerns about the suitability of any ingredients. And note: our serving size is for a Golden Retriever; your chihuahua is going to need a much smaller serving!
