"Comprehensive Review of Commercial Plant-Based Diets for Dogs"
Introduction
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.
The assessment focuses on whether dog foods, including those plant-based, adhere to the Association of American Feed Control Officials (AAFCO) guidelines, which are critical for validating the diets as complete and balanced. It evaluates both the traditional method of formulating diets to meet specific nutrient profiles and the utilization of feeding trials that test nutrient bioavailability and overall dietary sufficiency.

Why it matters to you?
1. Equivalence in Nutritional Assessment
Understanding that plant-based diets are evaluated by the same standards as meat-based options can reassure pet parents that these diets are scrutinized for nutritional adequacy in similar ways, promoting a level of trust in their completeness and balance.
2. The Importance of Feeding Trials
Highlighting the infrequency of feeding trials across all pet diets, not just plant-based, underscores the need for more rigorous testing within the pet food industry to ensure all marketed foods truly meet the nutritional needs of pets.
3. Advocating for Transparency and Higher Standards
Encouraging pet owners and veterinarians to inquire about the specifics of diet formulation and testing can lead to greater transparency and higher quality standards in pet nutrition. Knowledge about the manufacturing process and the scientific backing of diet claims helps pet parents make informed choices about what to feed their pets.
4. Special Nutritional Considerations
For dogs on plant-based diets, it’s crucial to ensure that all nutrient needs are met, especially those nutrients typically derived from animal products. Proactive measures, like checking vitamin D levels and using expert-formulated recipes for home-prepared diets, are recommended to prevent deficiencies.
Other Studies
"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.

"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.
