I'm so pleased to welcome the amazing Professor Andrew Knight back to The Plant-Powered Dog Podcast. In today's episode, Professor Knight discusses the implications of his ground-breaking new study on the animal welfare, environmental and sustainability effects of meat-based vs. plant-based diets for dogs, cats and people. The peer-reviewed study, "The relative benefits for environmental sustainability of vegan diets for dogs, cats and people" was published October 4, 2023 in PLOS ONE.
