Can anyone advise if this works. My elderly C. Spaniel doesn't enjoy bones and her teeth have tartar that needs removing in the easiest way possible. Plaque Off doesn't seem to do it very well and I remember a discussion a while back where Dentisept was mentioned, but I cannot remember if it was for the good or not. I just remember that you put some in the mouth and the tongue does the rest ( I think that is what I remember )
Grateful for any advice.

I found Aquadent worked fairly well, at least I thought I could see a difference when we tried it, you put it in the water. Only thing was you had to put fresh water and solution in every day, and with 2 bowls in the house it didn't take long to use up the whole bottle, and it wasn't cheap.
