Can Dogs Evolve to Eat Carbs?

In this Raw Pet Medics Plus One panel, Dr. Conor Brady and veterinarians Nick Thompson, Victor Sandecki, and Brendan Clarke dissect the widely‑cited AMY2B study that claims domestic dogs evolved increased amylase copy numbers to thrive on starch after the advent of agriculture. The group reviews the study’s premise (dogs have 2–20 copies of AMY2B versus wolves’ 2 copies, suggesting 50‑fold higher amylase activity), examines the evidence (gene copy number variation, breed‑specific differences, epigenetic regulation, and limited sample sizes), and challenges the leap from "survival" to "thriving" on high‑carbohydrate diets. They contrast carbohydrate digestion capacity with health outcomes, noting rising obesity, diabetes, and other chronic diseases in dogs fed ultra‑processed kibble. The panel highlights broader metabolic genetics (fat‑ and protein‑related genes such as ACSL5, ACSL4, SLC27A1, CYP2B11) that are more relevant to canine nutrition than AMY2B alone. They discuss methodological concerns (letter‑type publication, lack of peer review, possible industry funding, limited breed representation, and reproducibility), the role of epigenetics and microbiome adaptation, and the ethical implications of using the study to justify grain‑rich or vegan pet foods. The conversation ends with a call for more rigorous, breed‑wide research and a cautious stance on feeding dogs high‑carbohydrate diets despite any genetic capacity to digest starch.
