It makes no sense to brush your dog or cat's teeth with a paste that contains sugar (dextrose). The pets will injest the dextrose. I got too uncomfortable with the idea of using a paste that has dextrose. That defeats the purpose of brushing teeth.
I now use Cain and Able Kissable pet toothpaste (vanilla) which has no dextrose in it. Petrodex Natural toothpaste is also free of dextrose, but I prefer the Cain and Able Kissable. I buy it through amazon.com.
