I have been ordering Total-Zymes & Total-Biotics together & have witnessed the infinite benefits of these products. My puppy's coat is shiny & healthy & he no longer has issues w/flatus (thankfully!). I believe in the benefits of feeding probiotics for GI health & enzymes to aid in the digestion of high-quality kibble. I have ordered from this company several times & prefer their service over other companies, as well! Thank you!
