There are a number of items on the market to help with canine halitosis. I've heard bad things about at least one of them, but can't remember which one. I know that it was one of the green ones--little greenies? The thing that looks like a toothbrush? I don't know. I'm aware that some people brush their dog's teeth, but I don't think I'm going to go that far. Surely there is a good chewie product out there for doggy dental health and breath.
