If you’re dog already has bad teeth (tarter/plaque buildup), then I’d suggest trying a food additive made of seaweed. I carry a product called PlaqueOff that works incredibly well. Some people will use that all year long, but I suggest only using it once or twice a year… kind of like how we’d see the dentist for a professional cleaning once a year. In between uses of PlaqueOff you could use a water additive or foam/gel that will help fight bad teeth. Tropiclean makes a couple of products that work well.
One note, I’m not a fan of water additives, because you can’t tell how much of it your dog is getting each day. Do they drink the same amount each day? Probably not. So some days they will get a lot of the additive, other days not so much.
