I have been looking at CET and Petzlife products for Maddie's teeth. We *try* to brush but end up with a frustrated mommy and a sticky Yorkie face, lol.
Maddie uses rope bones and chews the way she is supposed too, when she is in the mood to chew on them, but Cooper eats and swallows them so it makes it difficult to have them in the house.
I am going to check out the Proden. A bottle lasts a year!!
That sounds like my kinda product.
