"Exploring Vegan Diets for Pets: A Systematic Review"
Introduction
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.
A systematic review of existing literature was conducted to critically evaluate the impact of vegan diets on the health of cats and dogs. This involved a detailed search through Medline, Scopus, and Web of Science, which identified 16 relevant studies. These studies were rigorously assessed for quality and the variety of health outcomes they measured, using tools such as the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The evidence found was diverse and often of low certainty, reflecting the need for more standardized and high-quality research.

Why it matters to you?
1. A Thoughtful Approach to Pet Nutrition
This study encourages pet owners to consider vegan diets as a potential option for their pets, especially if they are seeking alignment with their personal ethical beliefs. The absence of significant adverse effects in the reviewed studies offers some reassurance about the health implications of these diets.
2. Guided by Research, Not Rumor
Given the controversy and mixed opinions online, this comprehensive review serves as a crucial tool for informed decision-making. It helps pet owners base their choices on scientific evidence rather than conjecture, ensuring that any diet switch is supported by research findings.
3. Future-Focused Pet Care
The call for future research underscores the importance of continued exploration into this area. For pet owners, this means staying informed about new studies and developments, which can further guide and optimize their decisions regarding pet nutrition.
4. Safety First in Diet Changes
The recommendation to use commercially produced, nutritionally complete vegan diets if considering a switch is a practical guideline for guardians. It stresses the importance of ensuring that any diet meets the specific health requirements of their pets, avoiding potential nutritional deficiencies.
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.

"Clinical and Nutritional Evaluation of Vegan Diets in Dogs and Cats"
General Health:
Both dogs and cats appeared generally healthy; no significant health issues directly related to the vegan diet were observed.
Blood Test Results:
No substantial differences in blood values were noted for most nutrients in dogs. However, vegan cats showed significantly lower levels of folic acid compared to those on conventional diets.
The study identified some vegan pet foods that did not meet recommended dietary standards, highlighting potential risks of inadequate nutrient intake.
Nutritional Adequacies and Concerns:
While most homemade and commercial vegan diets seemed to fulfill basic nutritional needs for dogs, certain essential nutrients like methionine, cysteine, vitamin B12, and sodium were underrepresented in some cases.
Cats, due to their specific metabolic and dietary requirements, might be less suited to a vegan diet. Essential nutrients such as taurine, arachidonic acid, and vitamin A must be supplemented to prevent deficiencies.

"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.
