"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.

"Plant-Based Diets and Canine Health: Owner Perceptions and Reported Benefits"
Health and Wellbeing Comparisons:
Owners of dogs on plant-based diets reported fewer instances of ocular, gastrointestinal, and liver disorders compared to those feeding meat-based diets.
These dogs were also perceived to have greater longevity, indicating potential long-term health benefits of plant-based diets.
Interestingly, owners who chose plant-based diets for their dogs tended to consult veterinarians less frequently for nutrition advice.

"Exploring Vegan Diets for Pets: A Systematic Review"
The review found no conclusive evidence of adverse effects from feeding pets a vegan diet, and there were indications of some health benefits. However, the overall evidence was rated as low to very low in certainty, highlighting the complexity and variability in study designs and outcomes. This suggests that while vegan diets can be safe, the decision to switch should be approached with careful consideration of the animal’s nutritional needs.
