Hi there! Below, you will find my recommendations for the best probiotics for dogs and cats. Find the best match based on your pet’s species, age, health status, or medical diagnosis. As a holistic veterinarian, I use my experiences with patients to recommend the best products for each situation. I look for products that are as natural as possible and ones that do not contain potentially dangerous, harmful, or toxic ingredients. Additionally, for some health situations, I have found it best to use two products rotated. They are just beginning to explore this combination factor with human probiotics and I believe this approach can be very effective at supporting healing and restoring health in your pet.
