Study links some dog foods to higher climate impact than pet parents’ diets

Dogs fed premium, meat-rich diets may generate a larger dietary carbon footprint than their pet parents, according to a January 2026 study from researchers at the Universities of Edinburgh and Exeter. Using label and nutrient data from nearly 1,000 commercially available dog foods sold in the UK, the team found that wet, raw, and meat-rich products were linked to substantially higher greenhouse gas emissions than dry foods, while some of the highest-impact products generated up to 65 times more emissions than the lowest-impact options. The researchers estimate that ingredients used in UK dog food account for about 1% of the country’s total greenhouse gas emissions, and they argue that use of prime meat cuts rather than lower-demand by-products is a major driver of that difference.

Why it matters: For veterinary professionals, the study adds to a growing body of evidence that nutrition conversations increasingly overlap with environmental health, public health, and client expectations around sustainability. The authors say dry, non-grain-free diets generally trended lower-impact than wet, raw, or grain-free products, but they also caution that sustainability decisions still need to be balanced with nutritional adequacy and individual patient needs. That puts veterinarians in a key advisory role as pet parents ask whether lower-impact feeding choices can also support health. (news.exeter.ac.uk)

What to watch: Expect more scrutiny of pet food labeling, especially around meat sourcing, ingredient transparency, and whether sustainability claims become a more visible part of client decision-making. (news.exeter.ac.uk)
