What is dog food coloring?
Dog food coloring is any kind of color added to dog food. The purpose of this additive is to make the food more visually appealing to pet parents. Just like we are attracted to colorful foods, our dogs are as well. In nature, dogs are attracted to bright colors because it means that the food is fresh and full of nutrients.
However, when it comes to commercial dog food, the colors are often not natural. In fact, most of the time, these dyes are synthetic and have no nutritional value whatsoever. So, while your dog may be drawn to the colorful kibble, they’re not actually getting any benefits from it.
The earliest recorded case of manufacturers using food coloring was in 1880s when coloring was used to conceal spoilage or discoloration in non-fresh food. They contained several toxic chemicals including mercury, arsenic, and lead.
In 1906, the Food and Drugs Act banned the use of food coloring that was made with these toxic chemicals. In 1960, the US passed the Color Additives Amendments which brought more regulatory oversight on food coloring. However, there are still many synthetic dyes that are used in food today that have not been proven to be safe.
The three most common food colorings used in dog food are:
- Blue 2 – Also known as “brilliant blue,” this coloring is often used in cereals, sports drinks, and candy. It is derived from coal tar and has been linked to behavior problems in children.
- Yellow 5 – Also called “tartrazine,” this coloring is found in processed foods, cereals, snacks, and candy. It is derived from coal tar and has been linked to hyperactivity, migraines, and asthma in children.
- Yellow 6 – This color is used in many processed foods, cereals, snacks, and candy. It is derived from coal tar and has been linked to kidney tumors, bladder cancer, and adrenal gland tumors.
While the FDA considers these food colorings to be safe for human consumption, they have not been tested for long-term safety in dogs. In addition, dogs metabolize food differently than humans, so what may be safe for us could be toxic for them.
The table below has details on studies done on food dyes.

Natural vs synthetic food coloring:
There are two types of food coloring – natural and synthetic. Natural dyes are made from sources like vegetables, minerals, and invertebrates. On the other hand, synthetic dyes are created in a laboratory from petroleum products.
Most of the time, dog food companies use synthetic dyes because they’re cheaper and more consistent than natural dyes. However, this comes at a cost to your dog’s health.
Below are some examples of natural food coloring options
- Turmeric to produce dark yellow
- Spinach for green
- Cochineal bug to produce red
Synthetic dyes have been linked to cancer, organ damage, and behavioral problems in dogs. In addition, these dyes are often made from petroleum products, which can be toxic to your pup. So, if you’re looking for the best

First, synthetic dyes have been linked to health problems in dogs, including cancer. A study done by the National Academy of Sciences found that rats who were fed food dyed with yellow 5 and yellow 6 had an increased risk of cancer. While this study hasn’t been done on dogs, it’s still something to be aware of.
Second, food coloring can also cause allergic reactions in some dogs. If your dog is allergic to a certain dye, they may experience skin irritation, diarrhea, and vomiting.
