There is lots of controversy on here about angel eyes.
I did use it for tobi, and it cleared his staining up really fast. I kept him on, reducing the dose as directed, but stopped completely after less than 6 months.
He had no adverse reactions whatsoever.
My groomer also uses it on her dogs, and told me just to always advise your vet you are using it if you take the dog in for treatments.
Obviously you should read up on the different views and make up your own mind
