Vegan Dog Food: What to Know
Can dogs eat a vegan diet? What the Merck Veterinary Manual and a peer-reviewed 2016 review say - dogs can, if the diet is complete and balanced, and cats are a different case - what to check on the label, and two plant-based dog foods described from their makers' pages.
AI illustration This is a reading guide to published veterinary information and to what makers state on their own pages. If you want to feed your dog a plant-based diet, involve your vet, and do not formulate a homemade vegan diet yourself. This page is about dogs: cats are a different case, covered below.
The short answer: a dog can live on a plant-based diet if that diet is complete and balanced, and the hard part is making sure it is. The Merck Veterinary Manual says nutritional problems are rare when owners feed a good-quality, commercial, complete and balanced diet, or a homemade diet formulated by a board-certified veterinary nutritionist. They occur most often with unbalanced homemade diets. A peer-reviewed review reached a similar conclusion: dogs and cats may thrive on vegetarian diets, but these must be nutritionally complete and reasonably balanced (Knight and Leitsberger, 2016).
What the Evidence Says
- Dogs and cats differ. Merck lists ten essential amino acids for dogs. Cats need an eleventh, taurine, plus dietary vitamin A and arachidonic acid. Merck names vegetarian diets among the ones that cause nutritional problems when fed to cats. Plant proteins contain no taurine, so cats need animal-based protein or added taurine. That is why this page is about dogs.
- Problems are documented with every kind of diet. The 2016 review found nutritional inadequacies and health problems reported for vegetarian and meat-based diets alike. It also points to population studies and case reports of healthy dogs on vegetarian diets.
- Urine. The review advises owners to monitor urinary acidity regularly and to correct alkaline urine with suitable additives if necessary. That is a reason to involve your vet.
- Heart. Merck notes that some dogs, usually small breeds or dogs on grain-free diets, can develop a taurine-responsive form of the heart disease dilated cardiomyopathy. Both foods below state that they add taurine.
The review is a review of the evidence, not a feeding trial of any particular food, and its authors note limits in the studies they cover.
What to Check on a Plant-Based Food
- A complete and balanced statement for your dog’s life stage, the same test as for any food. Merck notes that in the United States, a food without one must be labeled as a treat or for occasional feeding (Merck).
- The protein figure and its sources, often peas, lentils and grains.
- Added taurine and L-carnitine, which the makers below list.
- The maker’s nutrition staff, and whether they answer questions about their formulation.

How we put this together. Two widely sold plant-based dog foods, described from their makers’ own product pages, checked on 26 October 2026. Neither page showed a full guaranteed analysis and AAFCO statement in the text we could read, so check the bag before you buy. Some makers’ pages also make claims about health outcomes from their own surveys. We have not repeated them, because they are not independent studies. We have not fed these foods. There are no prices here: the Amazon links search for the exact food, and we may earn a commission if you buy through them.
