Can dogs thrive on a diet without meat? It's a question that comes up more often as people look for ways to reduce their consumption of animal products, including in their pets' diets.
Dogs are adaptable eaters and can digest a variety of plant-based foods. However, being able to eat an ingredient doesn't necessarily mean it provides everything a dog needs to stay healthy.
A well-formulated vegan or vegetarian diet can meet a dog's nutritional requirements, but it takes more than removing meat and adding vegetables. Protein quality, essential amino acids, fatty acids, vitamins and minerals all need to be considered.
As an animal naturopath, I've always believed in looking at the individual animal, their natural dietary needs and what helps them thrive. I've also been eating a plant-based diet myself for over 30 years, so I understand why people want to explore meat-free feeding.
If you're considering a vegan or vegetarian diet for your dog, here's what you need to know.
What's the Difference Between Vegan and Vegetarian Dog Food?
Although the terms are often used interchangeably, there's an important difference.
Vegetarian diets exclude meat and fish but may include eggs and dairy products. These ingredients can provide useful sources of protein and other nutrients when eliminating meat.
Vegan diets exclude all animal-derived ingredients, including meat, fish, eggs, dairy and animal fats. Nutrients that would ordinarily come from these ingredients need to be supplied through suitable plant-based ingredients or added nutrients.
Both approaches require careful nutritional planning. A vegetarian diet isn't automatically balanced simply because it contains eggs or dairy, and a vegan diet isn't automatically deficient because it excludes animal products.
What matters is whether the finished diet provides all the nutrients your dog needs in the right amounts.
Can Dogs Thrive on a Vegan Diet?
Dogs have evolved alongside humans and can digest a variety of foods, including plant-based ingredients. They don't have the same strict dietary requirements as cats, which are obligate carnivores.
However, dogs still need a specific balance of nutrients to maintain their muscles, organs, skin, coat and overall health.
A properly formulated plant-based diet can meet these needs. The challenge is ensuring the diet is nutritionally complete rather than simply made from healthy-sounding ingredients.
A bowl of lentils, rice and vegetables might look wholesome, but it won't necessarily supply enough of every essential amino acid, vitamin, mineral and fatty acid. The same applies to a diet made up predominantly of commercial kibble if the food isn't formulated to be nutritionally complete.
The goal is to provide a diet that meets your dog's needs, not just one that avoids meat.
What Should a Plant-Based Diet Contain?
Protein and Essential Amino Acids
Protein is essential for muscle maintenance, tissue repair, enzymes and many other bodily functions.
Plant-based protein sources include:
-
Lentils
-
Chickpeas
-
Beans
-
Peas
-
Soybeans
-
Other suitable legumes and grains
These ingredients can contribute valuable protein, but the amount of protein alone doesn't tell the whole story. Dogs need adequate quantities of all essential amino acids, and the digestibility and balance of those amino acids matter too.
A well-formulated diet accounts for these requirements rather than relying on one or two protein sources.
Essential Fatty Acids
Fats provide energy, support cell function and help maintain healthy skin and coat.
Flaxseed, linseed meal and hemp seeds provide plant-based fats, including the omega-3 fatty acid alpha-linolenic acid (ALA). However, ALA isn't the same as EPA and DHA, and dogs convert ALA to these longer-chain omega-3 fatty acids only to a limited extent.
When feeding a vegan diet, the overall fatty acid profile needs to be considered rather than assuming that any plant oil will provide everything required.
Vegetables and Fibre
Vegetables can add fibre, texture and a range of nutrients to suitable meals.
Dog-safe options include pumpkin, zucchini, carrots, green beans, broccoli and cauliflower. Depending on the ingredient, finely chopping, blending or lightly cooking vegetables can help make them easier to digest.
Vegetables are useful additions, but they shouldn't displace the protein, fats and other nutrients needed for a balanced diet.
Carbohydrates and Grains
Rice, oats, quinoa and other grains can be included in a plant-based diet where appropriate. Dogs can digest properly prepared starches, although individual tolerance varies.
The key is balance. A diet containing excessive amounts of grains or other carbohydrate sources may provide plenty of energy while falling short in other nutritional areas.
Essential Nutrients to Consider
One of the biggest challenges with a home-prepared vegan diet is getting every essential nutrient right. Some nutrients deserve particular attention.
Taurine and L-Carnitine
Taurine plays important roles in normal heart function, vision and other bodily processes. Dogs can generally produce taurine from other amino acids, but their ability to do so depends on factors including the diet and individual metabolism.
L-carnitine helps transport fatty acids into cells for energy production. Its role and dietary requirements also need to be considered when formulating a diet.
Neither nutrient should be supplemented blindly. The aim is to ensure the complete diet supplies what's needed, rather than adding individual nutrients without considering the rest of the formulation.
Vitamin B12
Vitamin B12 is essential for normal blood cell formation, nerve function and metabolism.
A vegan diet must provide a reliable source of vitamin B12. Plant foods shouldn't be assumed to contain adequate amounts of this vitamin simply because they're rich in other nutrients.
Vitamins and Minerals
Calcium, phosphorus, zinc, iron, iodine, vitamin D and vitamin E are among the nutrients that need careful consideration.
For example, calcium and phosphorus must be supplied in appropriate amounts and proportions. Kelp can provide iodine, but its iodine content can vary considerably, so it isn't something to add indiscriminately.
Wakame is a highly nutritious seaweed that contains a range of trace minerals.
This is why a balanced formulation matters more than simply including a long list of nutritious ingredients.
Should You Make Your Dog's Food at Home?
Home-prepared meals give you control over the ingredients, which appeals to many people who prefer fresh food and want to know exactly what goes into their dog's bowl.
However, creating a complete vegan diet at home is more complicated than combining legumes, vegetables, grains and a general nutritional supplement.
If you're preparing meals from scratch, use a recipe that's been formulated to meet your dog's full nutritional requirements. Follow the specified ingredients and supplementation instructions rather than substituting ingredients or guessing the amounts.
A recipe that works for one dog may not suit another, particularly when their age, size, activity level or health needs differ.
Puppies have additional nutritional requirements because they're growing, so don't use an adult maintenance recipe for a puppy unless it's specifically formulated for growth.
Choosing a Commercial Plant-Based Dog Food
For people who want to feed their dogs a meat-free diet without preparing every meal from scratch, a commercially prepared plant-based food can be a convenient option.
Look for a food that's formulated to be nutritionally complete for your dog's life stage. Check the manufacturer's nutritional information and feeding instructions, rather than relying on the ingredient list or the words 'natural' and 'plant-based'.
Greenpet stocks the following options.
V-Planet Vegan Kibble
V-Planet Vegan Kibble is a plant-based dry dog food made with pea and lentil protein. It's formulated to meet AAFCO nutrient profiles for adult maintenance and includes added vitamins, minerals, taurine and L-carnitine.
It's intended for adult dogs, so choose a food specifically formulated for growth if you're feeding a puppy.
Veganpet Dog Food
Veganpet Dog Food is an Australian-made plant-based food formulated with added nutrients. Its current product information describes it as a complete vegan diet, so check the manufacturer's feeding guidance and life-stage suitability when choosing it for your dog.
Follow the manufacturer's transition instructions when introducing a new food and monitor how your dog responds.
What About Vegetarian Foods Such as Eggs and Dairy?
If you're feeding a vegetarian rather than a vegan diet, eggs and suitable dairy products can provide additional protein and other nutrients.
Plain yoghurt, cottage cheese and goat's milk may suit some dogs in small amounts, although not every dog tolerates dairy well. Eggs can also contribute useful nutrients.
However, adding eggs or dairy to a meat-free diet doesn't automatically make it complete. These ingredients need to be included in the context of the whole diet, with the remaining nutritional requirements accounted for.
Avoid onions and other foods that are unsuitable for dogs, and introduce new ingredients gradually.
How to Tell Whether Your Dog Is Doing Well
Whenever you change your dog's diet, pay attention to their overall condition.
Look at their:
-
Body condition and weight
-
Energy levels and general behaviour
-
Appetite and digestion
-
Skin and coat
-
Muscle condition and ability to maintain a healthy weight
These observations can help you notice changes, but they can't confirm that a diet supplies every essential nutrient. Nutritional deficiencies can develop before obvious signs appear.
If you're preparing meals at home, make sure the diet has been properly formulated rather than relying on appearance or short-term results alone.
