The ethics of vegan dog food is a highly debated topic. While some argue that vegan dog food is ethical because it does not harm other animals in the process of making it, others argue that it is not ethical because it may not provide dogs with all the nutrients they need.
Vegan dog food is typically made without any animal products or byproducts and may incorporate fruits, vegetables, cereals, legumes, nuts, and vegetable oils. Dogs are omnivores, not carnivores, and can derive nutrients from both meat and plants. They can also digest carbohydrates more easily than wolves. This suggests that a vegan diet could be suitable for dogs. However, there are certain nutrients that are harder to obtain through a plant-based diet, such as omega-3 fatty acids, calcium, vitamin D, and vitamin B12. As a result, vegan diets for dogs may require careful supplementation to ensure they are nutritionally complete.
Some studies have shown that vegan diets for dogs can be successful and may even be beneficial for dogs with allergies or advanced liver disease. However, other studies have found that vegan diets for dogs can be deficient in some nutrients and excessive in others. Ultimately, while it is possible to feed dogs a vegan diet, it requires careful attention to nutritional balance and consultation with a veterinarian to prevent dietary deficiencies.

What You'll Learn
Health benefits of a vegan diet for dogs
Dogs can be vegan
Dogs are omnivores, not carnivores, and so they can be vegan. Their anatomy enables them to digest and derive nutrients from both meat and plants. They have molars with flat surfaces to grind up fibrous plant material, they can digest most carbohydrates, and they can create vitamin A from beta-carotene found in plants.
A vegan diet can be nutritionally complete
A properly formulated vegan diet for dogs can be nutritionally complete. It may even be beneficial for dogs with allergies or advanced liver disease. There is no evidence of detrimental effects of vegetarian diets for dogs, and several scientific studies have shown meat-free diets to be successful. A 2023 analysis of existing research concluded that there is no convincing evidence of any major negative impact of vegan diets on dog health.
A vegan diet can be healthier
Traditional meat-based dog food can cause health problems for modern dogs. Nutritionally balanced plant-based dog food with the right natural ingredients processed to maximise their absorption and palatability may be healthier. A study of 144 female dogs found that feeding them less red meat lowered their risk of mammary cancer.
A vegan diet is more ethical
Traditional meat-based dog food harms cows, pigs, insects, and any animals killed to produce it. It is also neither natural nor healthy for the environment, as animal agriculture is one of the main causes of the current global climate change crisis.
A vegan diet can be tasty
A 2021 study suggests that dogs may find plant-based diets no less palatable than meat-based diets.
A vegan diet can be good for the environment
Switching a dog from a typical diet with meat to a vegan diet can reduce carbon emissions by 340 kg CO2eq per year. The agricultural land freed up if all the world's dogs were fed a vegan diet could feed an additional 450 million people.

Nutritional deficiencies in vegan diets for dogs
While dogs are omnivores and can survive on a vegan diet, there are certain nutrients that are harder or impossible to get through a plant-based diet. A vegan diet for dogs may lead to nutritional deficiencies, which can have serious health consequences.
Amino acids
Taurine and L-carnitine are essential amino acids that dogs cannot produce themselves, and there are not enough of them in plant-based diets.
Vitamins
Vitamin B12 and omega-3s are also much harder to get from common plant sources and are readily available in animal products. Vitamin D is a common concern with vegan dog diets, and dogs on a vegan diet may require additional vitamin D supplementation.
Minerals
Minerals such as calcium, iron, zinc, and copper are also more difficult to obtain through a plant-based diet.
Protein
Protein requirements are also more difficult to meet on a vegan diet, as plant proteins do not contain all the essential amino acids that dogs need.
Commercial vegan dog food
Commercial vegan dog food is available, but not all of them are nutritionally complete. It is important to consult with a veterinarian or animal nutritionist to ensure that a vegan diet meets a dog's nutritional needs.
Supplements
Supplements can help address some of the nutritional deficiencies of a vegan diet, but it is important to work with a veterinary nutritionist to choose the right supplements and ensure they are digestible for the dog.

Environmental impact of vegan dog food
The environmental impact of vegan dog food is a complex and multifaceted issue that has gained increasing attention in recent years. With the rise of veganism and the growing concern for environmental sustainability, it is essential to explore the ecological consequences of plant-based diets for dogs. This discussion will delve into the key aspects of this topic, providing insights into the carbon footprint, resource usage, and potential benefits of vegan dog food.
Carbon Footprint
The carbon footprint of vegan dog food is a critical aspect of its environmental impact. A life cycle assessment of vegan dog food found that each can of wet vegan dog food had a carbon footprint of 0.4 kg CO2-eq, resulting in a total of 443 kg CO2-eq over a dog's 15-year lifespan. In comparison, meat-based dog food often has a higher carbon footprint due to the energy-intensive nature of meat production. Switching to a vegan diet for dogs can lead to significant carbon savings, estimated at up to 340 kg CO2eq per year, or even higher if replacing high-quality meat sources.
Land Use and Water Usage
Land use and water usage are other important considerations in the environmental impact of vegan dog food. While vegan diets may reduce the amount of land needed for livestock grazing, they can also lead to increased land usage for crop cultivation. The type of crops and farming practices involved in vegan dog food production can vary, impacting the overall land use. Water usage is another factor, as vegan dog food may require less water compared to meat-based options, especially when considering the water-intensive nature of meat production.
Resource Usage and Pollution
The production of vegan dog food can have varying effects on resource usage and pollution. On the one hand, plant-based diets may reduce the demand for livestock farming, which is a significant contributor to water pollution and land degradation. On the other hand, the cultivation of certain crops, such as soy or palm oil, has been associated with deforestation and habitat destruction, particularly in regions like South America and Southeast Asia. Additionally, the use of pesticides and fertilizers in crop production can have detrimental effects on local ecosystems and water sources.
Benefits of Vegan Dog Food
Proponents of vegan dog food highlight several environmental benefits. Firstly, it can contribute to a reduction in greenhouse gas emissions, as mentioned earlier. Secondly, it may help conserve water resources and reduce water pollution associated with livestock farming. Thirdly, by eliminating the use of animal products, vegan dog food avoids the ethical concerns related to intensive animal farming practices and slaughterhouse waste. Lastly, vegan dog food can reduce the risk of certain health issues in dogs, such as exposure to contaminants or the consumption of low-quality meat by-products commonly found in conventional pet food.
In conclusion, the environmental impact of vegan dog food is multifaceted and depends on various factors, including the specific ingredients, farming practices, and production processes involved. While vegan dog food may offer benefits in terms of carbon emissions and water usage, it is essential to carefully consider the potential trade-offs in land use and pollution. Further research and transparent ingredient sourcing are needed to fully understand the ecological consequences of vegan dog food and make informed decisions regarding its sustainability.
