Before someone thinks and tells me how stupid this response sounds, I've never heard of the product or company before, and I didn't do any studying of the individual ingredients before answering. But purely based on the two statements keep out of reach of children and away from other pets and not intended for use for pregnant dogs or dogs used for breeding purposes I would not want to use it. To a fair degree tartar/bad teeth/bad breath is hereditary. Some dogs are just going to have bad teeth no matter how hard you try and some are going to be beautiful and the owner does nothing (that's me). But incase you are not aware of this, kibble makes teeth worse contrary to popular belief. If your dog already has a tartar problem and you can afford it, look into commercial raw, homemade raw, or a home-cooked diet. This will help with the teeth as well as healthy chews.
