We always recommend rotation of foods for many reasons. We also recommend rotation between brands.
A new peer-reviewed study published in the Journal of Animal Science found that nearly half of dog owners feed the exact same dog food every day, same brand, same flavor, little to no rotation. Researchers also found that protein source, especially chicken🐓, heavily influences purchasing decisions.
While consistency may help some sensitive dogs short term, long-term dietary monotony can reduce microbiome🦠 diversity and create a less resilient gut ecosystem over time. Different proteins, fibers, and plant compounds feed different beneficial bacteria, so repetitive diets may contribute to dysbiosis, weaker gut resilience, lower postbiotic production, and a greater risk of sensitivities and inflammatory issues.
The takeaway? Convenience and routine may come at the expense of microbiome diversity and long-term gut health.
If you cannot change your food, adding a variety of foods like veggies can also help nourish the microbiome by providing different types of fiber and plant compounds that feed beneficial gut bacteria. Probiotics as well can help support microbial diversity, strengthen the gut barrier, improve digestion, and increase resilience during stress, antibiotics, and dietary changes.
