Hello,
Yes, I have actually used the Duoxo pads. I got them from the vet and they work VERY good. I used them for a specific problem on the face, but I certainly see that they could also be used for tear stains and other problems as well. I see that someone was able to buy on-line which would be cheaper than from the vet.
They are very good to have and keep on hand.
Good Day~
