I had Jack's teeth cleaned last Wednesday and am now trying to brush them everyday and use the rinse. He thinks that I have totally lost my mind, and doesn't want to have anything to do with it!!!!!!!!!!!!! Chloe won't even let me get close to her with it!!! LOL I figure it's going to take a little time and patience. I wish I would have started this when they were pups. I'll definitely do that next time!
