Dog cookies are trending! Those oh-so-cute cookies elicit such joy in humans and that reaction really gets their furbabies excited. Unfortunately, those gourmet dog treats can get expensive, so many pet owners wonder if they can make homemade dog treats. Of course, to get those pretty colors, they have to use food coloring. Is food coloring safe for dogs, though? Below you will learn the answer to the question: can dogs have food coloring?

Can Dogs Have Food Coloring?

Food coloring is o.k. in moderation. In other words, you wouldn’t want to give your dog food coloring in small amounts. For instance, changing the color of the frosting on a dog cookie is fine.

Several reports have been released connecting the ingestion of artificial food coloring to brain tumors and thyroid tumors. As you will read below, there are conflicting views on whether artificial colors caused them.

To be extra safe, use natural food coloring. Natural food coloring vs. artificial food coloring is made from spices and powders, such as turmeric and beet powder. By deriving food dye from natural sources, you can be extra confident it won’t hurt your pooch.

What the FDA Says About Dogs Having Food Coloring

Purina and other dog food manufacturers use food dye in their products, but it’s approved by the U.S. Food and Drug Administration (FDA). The FDA has tested food dyes in pet foods and deemed them safe.

Artificial colors such as Red Dye 40 have received a lot of attention over the last few years because there has been some evidence of causing behavioral problems in children with ADHD. Considering this, many pet parents wonder if the same would be true for their furbabies. Fortunately, the FDA approves it and regards the evidence as inconclusive.

CSPI Answers the Question: Is Food Coloring Safe for Dogs?

The Center for Science in the Public Interest (CSPI) published a report stating, “Blue 2 cannot be considered safe given the statistically significant incidence of tumors, particularly brain gliomas, in male rats. It should not be used in foods.”

The CSPI found similar results for Red 40 and Yellow 5 in rats. You can read the full report here.

If the above information worries you, you can avoid any risks by choosing natural food coloring or pet safe food coloring.

Are Artificial Dyes in Dog Food Safe?
