Variety does more for your dog than you might think. A diverse diet is one of the most important things you can do for a healthy digestive system.
Here's the science, simply put. Your dog's microbiome is a complex community of micro-organisms living in their gut, forming a protective barrier against toxins, carcinogens and allergens. Emerging research suggests that the more diverse the diet, the stronger the microbiome, and a stronger microbiome means a healthier, happier dog.
If your dog isn't used to a varied diet, take it gently. A slow and steady introduction gives their gut the time it needs to adjust and get the most out of the change.
