Colorants appropriate for canine consumption are typically derived from natural sources, such as fruits, vegetables, and spices. For example, turmeric can impart a yellow hue, while beet juice can create shades of pink and red. These natural colorings avoid potentially harmful artificial ingredients.
Using natural colorants in canine treats and meals can enhance their visual appeal, making them more enticing. This can be particularly beneficial for picky eaters or when administering medication disguised in food. While vibrant colors in commercially produced human food often signal artificial ingredients, the historical use of natural colorants in animal feed predates modern industrial food production, demonstrating a long-standing practical and aesthetic purpose.
