A 10th study now supports the use of nutritionally-sound vegan dog food for our dogs and is yet further proof that we are all doing the right thing!
This latest study of 61 dogs at the University of Guelph by Dr Sarah Dodd et al. (2023) studied 31 dogs fed an experimental vegan diet (‘PLANT’) and 30 fed a commercial meat-based diet (‘MEAT’) for 3 months. Read the study here.
Vitamin D levels, bone composition and other health parameters were studied as Vit D is one of the essential vitamins needed to be added to all dog foods in just the right levels according to the FEDIAF requirements. Vit D has always been a very contentious subject regarding vegan dog food, as all meat-based dog foods have Vit D added from sheep’s wool (or lanolin). There are foods out there that can only be declared as vegetarian and not vegan as they have sheep’s wool (as lanolin or cholecalciferol) added instead of using Vit D from lichen or algae in its purest form (we only stock foods that have pure plant-based Vit D3 in them so all fully vegan!)
This latest study showed that –
“Bone mineral content and density did not differ from baseline values. Health status was maintained in dogs fed PLANT and Vitamin D2 [which is sourced from non-animal sources] appeared efficacious in maintaining serum total vitamin D concentrations and bone mineralisation. Findings support the hypothesis that PLANT was comparable to MEAT for maintenance of healthy adult dogs for at least 3 months.”
“The good thing about SCIENCE is that it’s true, whether or not you believe in it.”

Thank goodness for all our researchers doing such a valuable job of providing us with the evidence based medicine that we need!
We all love a bit of science and see all the published studies so far….

Survey of 1,189 North American dog guardians 2022
Dodd et al. (2022) collected dietary information from 1,189 dog guardians, including 357 feeding solely vegan diets, who fed these diets for 3 years on average. Vegan dogs were reportedly more likely to enjoy very good health, and less likely to suffer ocular, gastrointestinal and hepatic (liver) disorders. No health disorders were more likely, and longevity of previously-owned dogs was reportedly 1.5 years greater, when fed purely vegan diets.
The healthiest and least hazardous dietary choices for dogs, are nutritionally sound vegan diets
Prof Andrew Knight and colleagues (Huang E, Rai N, Brown H) published a groundbreaking research paper on the 13th April 2022 that stated from the findings of 2,639 dogs, that “the pooled evidence to date indicates that the healthiest and least hazardous dietary choices for dogs, are nutritionally sound vegan diets.”
Survey of 100 UK dog guardians
Davies (2022) surveyed 100 dog guardians who had switched to a nutritionally complete vegan dog food designed by UK veterinarians. “The vegan food was acceptable (palatable), and appetite and body weight were not adversely affected. Changes, including improvements, were reported and statistically significant at p< .05 in the following areas: activity, faecal consistency, frequency of defaecation, flatus frequency, flatus antisocial smell, coat glossiness, scales in haircoat (dandruff), redness of the skin (itching, inflammation), itchiness (scratching; pruritus), and anxiety.”
Peer review analysis of Prof Andrew Knight and Dr Sarah Dodd papers
Domínguez-Oliva et al. (2023) concluded, “there was no overwhelming evidence of adverse effects arising from use of these diets and there was some evidence of benefits. … Much of these data were acquired from owners via survey-type studies, but these can be subject to selection biases, as well as subjectivity around the outcomes. However, these beneficial findings were relatively consistent across several studies and should, therefore, not be disregarded.” They advised, “… if guardians wish to feed their companion animals vegan diets, a cautious approach should be taken using commercially produced diets which have been formulated considering the nutritional needs of the target species.” [i.e., that are nutritionally-sound].
Prospective clinical study of 15 dogs 2023
Linde et al. (2023) studied 15 dogs fed vegan diets (V-Dog ‘Kind Kibble’) for one year after previously being fed meat-based diets. They evaluated clinical, haematological (blood cells etc.), and nutritional parameters at 0, 6, and 12 months, including complete blood count (CBC), blood chemistry, cardiac biomarkers, plasma amino acids, and serum vitamin concentrations. All dogs maintained their health status. Three who had been overweight or obese lost weight. Blood results confirmed the diet provided all essential amino acids, and for several nutrients blood levels increased. In some cases previous deficiencies reversed, without supplement use.

Dog domestication reveals adaptation to a starch-rich diet
A fascinating study proving how mutations in key genes occurred allowing increased starch digestion in dogs relative to wolves. These results indicate that early ancestors of modern dogs could thrive on a diet rich in starch which constituted a crucial step in the early domestication of dogs.
