5 Things You Need to Know About GMOs Before Feeding Your Dog

5 Things You Need to Know About GMOs Before Feeding Your Dog

. 2 min read

GMOs have been a hotly debated human food topic ever since genetically modified foods were introduced in the 1990s. But it’s also become a controversial issue in the dog food world for the same reason: government regulation of these foods varies so much, it makes us wonder if we really should be feeding our pups those altered ingredients. We chatted with Robert Silver, a holistic vet in Boulder, Colorado about whether it's worth trying to avoid GMOs in your dog's diet.

Most dog food contains GMOs
Unless the food specifically states that it’s non-GMO, you can pretty much assume that it contains genetically modified ingredients, Silver says. That’s because 95 percent of corn and soy crops are GMO—and those are major ingredients in most traditional dog food. (Ollie is free of corn, soy and wheat!)

That’s because GMOs are present in almost everything
GMO crops have infiltrated every crop, according to the Organic Consumers Association. In fact, 93 percent of soy, 86 percent of corn and 90 percent of canola is GMO. Even if you’re purchasing grain-free dog food, it could still contain GMO, Silver says, as most animals are fed them.

There are potential downsides
Some studies have found that animals fed GM corn and soy had certain health conditions, though there has only been anecdotal evidence pairing GMOs with dog issues, specifically. “In some cases, we’ve seen that it makes the protein more allergenic than it had been, so we can see that it stimulates more allergens as a result,” Silver explains. “But these are things that may only happen in a smaller percentage of the animals.”

But the risks aren’t clear
There are billions of dogs and billions of humans who eat GMOs daily, but we aren’t seeing billions of problems derived from eating them, Silver says. “The reason is that the GMOs may not necessarily adversely harm everyone that easily,” Silver says.

If you want to try to avoid them...

You can start by looking for corn and soy-free food. But feeding your dog a diet that’s 100% organic—not certified organic—is the only way to guarantee it's really GMO-free—or you can source your own GMO-free ingredients and cook the food yourself (though of course, both come at a cost).
