New Study Confirms that Dogs Can Thrive on a Vegan Diet

A new study has confirmed that dogs can thrive on a vegan diet, showing improvements in key health markers such as vitamin D levels and tryptophan. The study, conducted by veterinarians Dr. Tonatiuh Melgarejo and Dr. Annika Linde, examined 15 dogs over a year and found that they maintained excellent health on a nutritionally complete vegan diet. The results, published in the scientific journal PLOS ONE, showed that imbalances that were present in dogs on meat-based diets diminished or disappeared.

The findings have been turned into a Netflix film directed by Academy Award-winning filmmaker Louie Psihoyos and provide compelling evidence that plant-based diets can sustain dogs and possibly improve their overall health. Other studies around the world have also concluded that dogs can thrive on a plant-based diet, challenging the belief that dogs are obligate carnivores.
