I'm intrigued by a product I've come across on the internet called Leba III. Apparently it's a natural herbal concoction that you spray on dogs' and cats' teeth and over time removes plaque. Sounds like a good way to avoid or postpone veterinary teeth cleaning. If it works and is safe. I've found plenty of places that sell it, but I can't find much information about it. Has anyone used this product and/or have more information about it? Thanks....
