This product is amazing! They wanted to do dental surgery on my little dog but then I found Dentatreat. Within weeks my dogs teeth were whiter and the gum swelling was gone. She has been on it for 6 months now and only has a little staining left. NO SURGERY NEEDED. My bichon is allergic to many foods and this did not bother her at all. In fact if I don't put it on her food she whines.
