I just lost my second dog to anesthesia given for dental care. Different vets, different ages. I will avoid any further anesthesia. Am trying the CET Hexa and hhope it works. So far so good. I will never have their have a dog go through cleaning again. My.dogs would be alive today if I did not have that done. I have dachshunds who will not allow brushing, wiping, etc. Of teeth or nails. If these chews don’t work I need some that do.
