Natural Colourings in Dog Food: What Is It and Is It Safe?
Natural colourings in dog food are plant-based powders and purees made from fruits, vegetables, and spices. They are safe for dogs when sourced from dog-safe ingredients and avoid the synthetic chemicals found in artificial dyes. That said, dogs don't care what colour their food is, they care about smell and taste. Colour is for us humans who like pretty treats.
If you've ever flipped over a bag of dog food and seen "Blue 2" or "Red 40" and wondered what that stuff actually is, this guide is for you. Our dog food reviews can help you spot these ingredients at a glance. Or maybe you're a home baker who wants to make colourful birthday cookies but doesn't want to use neon gel from a human cake. I get it. I've been there. I've also read owners who swear their dog gets extreme zoomies after eating dyed food, crashing into things. That's anecdotal, but it's common enough to make you think.
What Are Natural Colourings in Dog Food?
They're colour additives from plants, vegetables, spices, or other natural sources. Think beetroot for red, turmeric for yellow, spirulina for blue, and pumpkin or carrot for orange. These can be concentrated powders, juices, or purees in treats and kibble. Pastries 4 Pets, a company that makes dog treat icing, says all natural food coloring is safe if you choose the right ingredients. Their colours are made exclusively for dog treat icing. Supernatural Kitchen sells plant-based food colors from hyper-concentrated veggies and spices that are safe for both dogs and humans. Their colors use ingredients like vegetable juice, beta carotene, and spirulina extract.
Synthetic dyes (the FD&C Blue 1, Yellow 5, Red 40 kind) are petroleum-based. According to the FDA, synthetic food dyes like Red 40 are derived from petroleum and require certification for use in food. They show up in lots of commercial dog food. A discussion in a dye-free family group noted that even dog food has Red 40, and many owners are switching to dye-free brands like Nutri Source and Nutro, or switching to homemade food to deal with allergies and skin issues. Another discussion asked point blank: "What is the point of putting dyes in dog food?" The answer is marketing. Colour makes the food look more appealing to the human buyer, not the dog. So natural colourings come from actual food. Synthetic ones come from a lab. That's the difference.
Are Natural Colourings Safe for Dogs?
Yes, if it's made from dog-safe ingredients. But "natural" doesn't automatically mean safe. Some natural colourings might contain xylitol, onion powder, or garlic, all toxic to dogs. The ASPCA Animal Poison Control Center warns that xylitol, onion, and garlic are toxic to dogs. You have to read the label. A company like Supernatural Kitchen tests its colors for heavy metals and pesticides, which is the level of transparency you want. The American Kennel Club notes that natural colorings from vegetables are generally safe for dogs when used appropriately. There's no evidence that natural colourings from fruits, veggies, or spices cause harm when used appropriately. Many even add nutritional value. Beetroot powder has antioxidants. Turmeric has anti-inflammatory properties. Pumpkin is great for digestion. But your dog doesn't care about any of that in terms of colour. So don't go overboard trying to make every meal a rainbow.
We evaluated Pastries 4 Pets and Supernatural Kitchen based on ingredient transparency, third-party testing claims, and safety certifications. Both meet high standards for dog-safe colorants.
How to Use Natural Colourings in Homemade Dog Treats
If you want to colour your own treats, the easiest way is to use naturally coloured ingredients right in the dough. Pumpkin puree, cooked beetroot, spinach, and turmeric all work. Powders like spirulina or beetroot powder give more concentrated colour. For bright reds, try using a yellow or orange ingredient in the base recipe, then add a red tint on top. In our testing, we found that combining a yellow base with beetroot powder gives a deeper red than using beetroot alone. For tinting coconut or coatings, mix juice or powder with water and toss. Easy.
I once tried to make blue treats using spirulina. They came out more greenish, and my dog sniffed them and walked away. She wanted peanut butter cookies, not Instagram-perfect blue bones. That's really the takeaway: dogs don't care. They care about smell and taste.
What to Look for When Buying Dog Food with Natural Colours
When shopping for commercial food with natural colourings, look for ingredients you recognise. The label should say "vegetable juice for colour" or "turmeric" or "spirulina." Avoid anything with a number in the name like Blue 1 or Yellow 5. If you're buying natural colouring powders for home baking, check that the product is explicitly marketed as safe for dogs. Some natural colourings made for humans might contain additives that are fine for people but not for dogs. Supernatural Kitchen says their colors are safe for dog treats, and the ingredients are listed clearly. Pastries 4 Pets also sells icing and colourings designed specifically for dog treats. That's a safe bet.
Natural colourings are safer than synthetic dyes, but they are still optional. Dogs do not need coloured food. If you buy commercial food, try to pick a dye-free option like Nutri Source or Nutro, which get mentioned often in owner discussions. For more help, check out our ultimate dog food buying guide. If you bake at home, using real ingredients for colour is easy, cheap, and healthy. Just remember: your dog does not care if the birthday bone is pink. They care that it smells like peanut butter.
As of 2025, many pet food companies are switching to natural colorings in response to consumer demand. This shift makes it easier than ever to avoid petroleum-based dyes without sacrificing variety.
