I chew on plastic bags because it's the only thing that makes the ache go away. I drool more than I used to. I even bit her once, not because I wanted to, because it hurt and I didn't know how else to say it. She tried the toothbrush. I hate it. She tried the dental chews. I wouldn't even touch them My friend down the street doesn't fight any of it anymore. His owner puts Purriq dental powder on his food, and he says it just tastes like part of dinner. That's the one I want. 60 day guarantee, link below.
