You should never use YOUR toothpaste for your dog (as convenient as that may be). Human toothpaste contains soap. That's what makes it foam. But soap shouldn't be ingested, and smart as your dog may be, you're probably not going to teach him to rinse and spit! KIssable vanilla flavored toothpaste is All Natural and is specifically formulated to be safe for dogs (and their people) It contains Tea tree oil, which helps fight plaque and is naturally sweetened with Stevia. But more importantly it uses a mild abrasive to clean teeth and disinfect the whole mouth. Use Kissable toothpaste with a Kissable brush for a clean mouth and fresh breath.
