How can I make dog-friendly icing?

To make dog-friendly icing, you can use ingredients like plain yogurt, peanut butter, or mashed banana as a base. Avoid using ingredients like sugar, chocolate, or artificial sweeteners, as they can be harmful to dogs. Mix the chosen base with a small amount of water to achieve a smooth consistency, then spread or drizzle it over your dog's treats for a tasty and safe icing option.
