Over recent years, people have become increasingly health-conscious. They have become eager to pick up healthier habits, such as exercising regularly and going vegan. 

If you have also made the switch to vegan diets, you know how this choice improved your overall well-being in many ways. It may have helped you reduce excess weight, lower your risks of developing heart diseases, give your body more of certain nutrients, and so on. 

Given all of these health benefits, you naturally want your loved ones to experience the same—including your furry friends. However, this may lead you to wonder, “Is a vegan diet healthy for dogs?” 

On that note, allow us to share three of the many studies conducted in the past years about vegan nutrition for dogs: 

1. Pia Gloria Semp’s 2014 Study (2014)

This study conducted by veterinarian Pia Gloria Semp included a clinical evaluation along with a blood test of randomly selected 20 dogs. The owners were also asked to accomplish a questionnaire about how the vegan diet with their dogs went. 

Some factors observed in the study are the dog’s general health, the state of the body, and their cardiovascular, respiratory, and digestive vital signs. Their coat and fur along with their excretion were also observed. 

The owners of dogs that transitioned to vegan food reported observing brighter and healthier coats. Some dogs also demonstrated recovery from dermatological issues such as skin problems, oily fur, and the like. Ultimately, going vegan did not bring about any irregularities related to nutrition. 

2. W. Brown and Colleagues’ Study (2009)

This study involved 12 sprinting Siberian huskies. Six (6) of them were given commercial food designed for active dogs, while the remaining half (6) of them were provided meatless dog food. This contained the same nutritional value as the former. The main difference is that the commercial dog food contained 43% of poultry meal, while the latter contained gluten and soy mixture instead. 

The Siberian huskies were given such food for 16 weeks; in 10 of those, they have been competing regularly. 

After the study, Brown and colleagues discovered that all dogs were in great physical condition. Despite the differences in the diet, no Siberian husky was found to be anemic or possessing other medical conditions. 

3. PETA Study (1994)

This research conducted by the People for the Ethical Treatment of Animals or PETA was made through a systematic study involving 300 dogs. These all came from different locations across American and Canada. 

All of the dogs were on a meatless diet, with 65.3% of them being vegan and 34.7% being vegetarians. Furthermore, they were of different ages, breeds, and sexes. 

The result of the study showed that a majority of the dogs who were vegan or vegetarian were in “good” or “excellent” health conditions for most of their lives. 


The three studies mentioned above are just some of the many research made on the effect of plant-based diets on dogs. These all show that giving your furry friends vegan food choices will not do any harm to them; on the contrary, it can even improve their health and well-being. If you are interested in bringing your pup along your vegan journey, there’s no reason to worry! As long as you have the right vegan food for your dogs, they’ll be sure to enjoy a healthy and delicious meal.
