Grain-free diets were once touted as a healthier choice for dogs. This was especially true for dogs with allergies or digestive sensitivities.

Many pet parents believed that, like human gluten-free diets, removing grains (such as corn, wheat, and rice) from their dogs\u2019 food would reduce allergies or improve overall health. Some brands also marketed grain-free foods as being more \u201cancestral\u201d or closer to a dog\u2019s natural diet.<\/p>\n<p data-start=\"1009\" data-end=\"1294\">However, <strong data-start=\"1018\" data-end=\"1059\">true grain allergies in dogs are rare<\/strong>\u2014less than 1% of diagnosed canine food sensitivities are linked to grains themselves.
