"Evaluating the Health Impacts of Vegan Diets for Dogs: A Guardian’s Perspective"
Introduction
General Health and Well-being: Most guardians reported no negative impact on their dogs’ appetite or body weight, suggesting that the vegan food was palatable and satisfying.
Statistically Significant Improvements: Improvements were noted in several areas, all statistically significant:
Increased activity levels and better fecal consistency.
Reduced frequency of defecation, less frequent and less smelly flatus.
Enhanced coat glossiness and reduced dandruff.
Decreased skin redness and itchiness.
Lowered anxiety levels in dogs.

Participants in this study were dog guardians who completed an online survey assessing various health indicators using a Likert Scale. The survey covered aspects like appetite, body weight, activity levels, digestive health, skin and coat condition, and behavior changes.

Why it matters to you?
1. Potential Health Benefits of Vegan Diets
This study highlights possible health benefits associated with vegan diets for dogs, as reported by their guardians. Such benefits include better skin and coat health, improved gastrointestinal health, and enhanced overall activity.
2. Insight for Informed Dietary Choices
By documenting these health impacts through guardian observations, the study provides valuable insights that can help other pet parents consider whether a vegan diet might be appropriate for their dogs.
3. Need for Further Research
The findings underscore the importance of conducting more detailed, controlled clinical trials to fully understand and verify the benefits and any potential risks of vegan diets for dogs.
Other Studies

"Comprehensive Review of Commercial Plant-Based Diets for Dogs"
Nutritional Standards and Testing:
Plant-based dog diets are typically formulated to meet AAFCO nutrient recommendations, similar to meat-based diets, although actual feeding trials are rare in the industry.
The critique often directed at plant-based dog food regarding untested nutritional claims is also applicable to many meat-based diets sold commercially, which frequently rely solely on nutrient profile formulations without feeding trial verification.
Additional tests such as dietary nutrient analysis and digestibility can further substantiate the nutritional claims of these diets, though such information is seldom disclosed on product packaging or promotional materials.

"Navigating Vegan Diets for Pets: Evaluating Health Impacts and Guardian Choices"
In this comprehensive survey exploring canine diets, it was found that dogs on vegan diets generally exhibited the fewest health issues, suggesting that this diet might be the healthiest option available. Although those on raw meat diets also showed relatively good health outcomes, these diets carry inherent risks including nutritional deficiencies and the presence of pathogens. Additionally, the overall better health associated with raw meat diets may partly be attributed to the fact that dogs on these diets were typically younger.

"From Wolves to Dogs: Uncovering the Genetic Journey of Domestication"
Brain Function and Behavior: Nineteen genomic regions linked to brain function were identified, with eight involved in nervous system development—these may explain the behavioural adaptability of domestic dogs compared to their wild ancestors.
Dietary Adaptations: The study also found signals of selection in ten genes associated with starch digestion and fat metabolism, suggesting that early dogs evolved to digest starch more efficiently than wolves. This adaptation was crucial as it allowed dogs to thrive on a diet different from the strictly carnivorous one of their wolf ancestors.
