Vegan dogs live longer: NEW STUDIES SUPPORT NUTRITIONALLY SOUND VEGAN DOG FOOD!
Prof Andrew Knight has done it again by publishing some key studies this week on his website that show that nutritionally-sound vegan dog food diets extend the lifespan of your dog!
Dodd et al. (2022) collected dog food information from 1,189 dog guardians, including 357 eating only 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 eye, gastrointestinal and liver disorders. Longevity of previously-owned dogs was reportedly 1.5 years greater, when fed purely vegan diets.
Davies (2022) surveyed 100 dog guardians who had switched to a nutritionally complete vegan dog food. Clear improvements after 3 – 12 months were reported in coat glossiness, dandruff, itchiness, external ear canal crusting, faecal consistency (see Blog below:), antisocial smell and anxiety.
“There are now eight studies or veterinary masters theses, examining health outcomes in dogs maintained on vegan or vegetarian diets. Seven studies now support the use of these diets. The weight of evidence now overwhelmingly supports the use of nutritionally sound vegan dog food.”

These published papers are a huge boost for all of us feeding our own dogs a nutritionally sound vegan dog food diet as we now know that we WILL have our dogs around for longer. JUST BE KIND will be publishing a number of stories of amazing dogs over the next few weeks that back up these studies.
