You probably didn't know this but you can't just 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 not going to teach him to spit! The vanilla flavored toothpaste is All Natural and is great for dogs and their people! It contains Tea tree oil, which helps fight plaque and is naturally sweetened with Stevia.
