A number of my vegetarian clients have asked me whether or not their dogs can be vegetarians too. Their main concern is whether or not a meat-free diet is appropriate for their dogs. If it isn’t, they’ll continue, albeit squeamishly, to feed their dogs foods that contain meat.
I’m a vegetarian myself, and I like being the bearer of good news, so this is a fun conversation for me. The answer is yes — dogs can eat a vegetarian diet and thrive.
While this topic is certainly interesting to vegetarians, owners who don’t have issues feeding their dogs meat should also pay attention. Here’s why:
It is true that dogs belong to the order Carnivora, but they are actually omnivores. The canine body has the ability to transform certain amino acids, the building blocks or protein, into others, meaning that dogs can get all the amino acids they need while avoiding meat.
Being a lacto-ovo vegetarian does not present many nutritional challenges for people or for dogs. In fact, eggs have the highest biological value of all the protein sources commonly used in pet foods. The biological value of a protein measures its ability to supply the individual amino acids that an animal needs. Eggs are an excellent source of protein for dogs. Even veganism — consuming a diet that does not include any animal products — though a little trickier, is possible for dogs. The right balance of different plant-based sources of protein (e.g., beans, corn, soy and whole grains) can still provide the needed amino acids.
So why should non-vegetarians care about this? Because it helps make sense of the confusing information about canine nutrition that exists. Think of it this way, if dogs can live long and healthy lives eating a diet that is made from only plant-based sources of protein, why wouldn’t these ingredients also be appropriate for use in foods that contain meat? Using both animal and plant-based sources of protein in a non-vegetarian dog food makes perfect sense.
The only issue I’ve seen with dogs being switched to a vegetarian food is one of acceptance. It seems to me that dogs who are used to eating diets that contain meat go through a “where’s the beef, chicken … etc.?” stage. Overcoming this is easy if you simply mix increasing amounts of the new food in with decreasing amounts of the old and make the change slowly.
So, if feeding meat to your dog presents an ethical quandary for you, options are available. And even if you’re happy that your dog’s food contains meat, know that the inclusion of plant-based sources of protein helps to balance the diet’s nutritional profile.

Have you ever wondered if your furry friend could thrive on a meatless diet? As more humans embrace vegetarian and vegan lifestyles, many pet owners start questioning whether their dogs can join them. It’s a topic that sparks passionate debates among dog lovers veterinarians and animal nutritionists alike. Let’s dig into the real facts about whether dogs can survive without meat and what science has to say about it.
The Carnivore vs. Omnivore Debate
First things first – many people believe dogs are strict carnivores who need meat to survive. But is this actually true?
Dogs are often mistakenly classified as carnivores. While they descended from wolves (who are definitely meat-eaters capable of consuming up to 20 pounds of meat in one meal), domesticated dogs have evolved differently.
The reality is that dogs are actually omnivores – animals that can consume and digest both animal and plant foods This is backed by scientific evidence
- Dogs produce amylase in much greater quantities than wolves, which helps them digest starches and plant matter
- Dogs have adapted digestive systems that can process a more varied diet than their wolf ancestors
- Dogs can derive nutrients from both plant and animal sources
However, some scientists still classify dogs as carnivores because they have:
- Long canine teeth designed for tearing meat
- Shorter gastrointestinal tracts compared to typical omnivores
- Different enzyme production patterns (dogs don’t produce amylase in their saliva like humans do)
Dr. Jerry Klein, AKC chief veterinary officer, puts it this way: “Whether dogs are classified as carnivores or omnivores, I think most veterinarians would agree that over the centuries, the digestive system of dogs has adapted to allow them to eat and even to require a more complex diet than that of the wolf.”
Can Dogs Actually Live Without Meat?
The short answer Technically yes but it’s complicated.
Dogs can technically survive without meat, but there are several important factors to consider:
-
Protein Requirements: Dogs need more protein than humans do. While they can get protein from plant sources, it’s harder to meet their needs without meat.
-
Essential Fatty Acids: Meat provides crucial fatty acids for skin, coat, and eye health. Dogs on meatless diets often need supplements to avoid deficiencies.
-
Complete Nutrition: Simply removing meat without proper substitution can lead to serious health problems.
Dr. Jennifer Coates, a veterinarian who is herself a vegetarian, states: “Dogs can eat a vegetarian diet and thrive. The canine body has the ability to transform certain amino acids, the building blocks of protein, into others, meaning that dogs can get all the amino acids they need while avoiding meat.”
But this doesn’t mean just any vegetarian diet will do! A properly balanced meatless diet requires careful planning and usually professional guidance.
Warning Signs Your Dog Isn’t Thriving Without Meat
If you’re considering a meatless diet for your pup, watch out for these signs of potential malnourishment:
- Shaking or weakness
- Lack of focus or mental clarity
- Head bobbing
- Unexpected weight loss
- Itchy or flaky skin
- Disinterest in food
- Dull coat
These symptoms could indicate your dog isn’t getting the essential nutrients they need from their meatless diet.
Historical Perspective: Have Dogs Always Eaten Meat?
Before commercial dog food existed, dogs often ate whatever their humans could spare – including table scraps that sometimes contained little to no meat. But there’s limited historical evidence of dogs thriving long-term on completely meatless diets.
The Merck Veterinary Manual warns that “nutritional problems occur most commonly when dogs and cats are fed imbalanced homemade diets. Dog or cat foods or homemade diets derived from a single food item are inadequate.”
This reminds us that diversity in nutrition has always been important for dogs, regardless of whether meat is included.
The Science Behind Meatless Diets for Dogs
Let’s talk about what your dog actually needs nutritionally:
Protein Requirements
Dogs absolutely require protein to live – that’s non-negotiable. But the protein doesn’t necessarily have to come from meat. Alternative protein sources include:
- Eggs (highest biological value of all protein sources commonly used in pet foods)
- Dairy products (for vegetarian, not vegan diets)
- Legumes like chickpeas and lentils
- Quinoa
- Soy products
Essential Nutrients Typically Found in Meat
Several critical nutrients that dogs naturally get from meat must be supplemented in a meatless diet:
| Nutrient | Importance | Plant-Based Sources |
|---|---|---|
| Taurine | Heart health | Synthetic supplements |
| L-carnitine | Energy metabolism | Synthetic supplements |
| Vitamin B12 | Nervous system function | Nutritional yeast, supplements |
| Omega-3 fatty acids | Skin, coat & brain health | Flaxseed, algae oil |
Making the Transition: How to Feed a Dog Without Meat
If you’re determined to try a meatless diet for your dog, follow these steps to do it safely:
-
Consult a veterinary nutritionist first – Most online information about balanced vegan/vegetarian diets for dogs is incorrect or incomplete. Get professional help!
-
Transition gradually – Mix increasing amounts of the new food with decreasing amounts of the old over 1-2 weeks.
-
Consider commercial options – Some commercially available vegetarian and vegan dog foods are formulated to meet all canine nutritional requirements.
-
Regular health monitoring – Schedule more frequent vet checkups during the transition and first year.
-
Supplement wisely – Work with your vet to determine which supplements your dog needs.
Dr. Klein advises: “If a homemade diet is your choice, work closely with your veterinarian or a veterinary nutritionist to be sure that the recipe is comprehensive and includes all of the nutrients your dog requires to stay healthy and active.”
Who Should NOT Feed Their Dog a Meatless Diet
Some dogs should definitely continue eating meat-based diets:
- Puppies (still developing and have higher nutritional needs)
- Senior dogs with specific health conditions
- Dogs with certain digestive disorders
- Working dogs with extremely high energy requirements
- Dogs with allergies to common plant proteins
Always prioritize your dog’s health over dietary ideology. If your dog has specific health issues that require animal proteins, respect those needs.
My Personal Experience
I’ve had friends who’ve successfully transitioned their adult dogs to carefully planned vegetarian diets. One buddy’s Labrador has been vegetarian (not vegan) for over 3 years and is doing great according to vet checks. His diet includes eggs, some dairy, and a variety of plant proteins.
But I’ve also seen a neighbor’s attempt go badly when they simply removed meat without proper substitution – their poor pup developed skin problems and lethargy until they consulted a vet nutritionist.
The Bottom Line: Possible But Proceed with Caution
Can dogs survive without meat? Yes, with careful planning and professional guidance.
Is it easy or right for every dog? Definitely not.
The most important takeaway is this: If you’re considering a meatless diet for your dog, do it with expert help and prioritize your dog’s health above all else. A balanced diet that meets all nutritional requirements should be your goal, regardless of whether that includes meat.
And remember, even if you choose to keep meat in your dog’s diet, knowing that dogs are omnivores helps explain why quality commercial dog foods contain both animal and plant-based ingredients. This balanced approach often provides the best of both worlds!
FAQs About Dogs and Meatless Diets
Are there any commercial vegetarian dog foods that are nutritionally complete?
Yes, several companies now make vegetarian and vegan dog foods formulated to meet AAFCO nutritional guidelines. Always check with your vet before switching.
Is it easier to feed dogs a vegetarian diet rather than a vegan one?
Yes! Lacto-ovo vegetarian diets (including eggs and dairy) are much easier to balance for dogs. Eggs have the highest biological value of all protein sources commonly used in pet foods.
Do dogs on meatless diets need supplements?
Almost always. Most dogs on meatless diets need supplements for nutrients naturally found in meat, including certain amino acids, vitamins, and fatty acids.
How long does it take to transition a dog to a meatless diet?
Generally 1-2 weeks, gradually mixing increasing amounts of the new food with decreasing amounts of the old food.
Can puppies eat a meatless diet?
It’s not recommended. Puppies have specific developmental needs that are more challenging to meet with a meatless diet.
