Dear Dr. Alice, What is bad about human toothpaste for dogs? Sincerely, Paste-y


Dear Paste-y,
Most of the pastes have an artificial sweetener in them called xylitol. And this fake-sugar causes the insulin circuit within the dog to get screwed up unlike our insulin circuitry. They can suddenly get really low in blood sugar as a result of ingesting the xylitol and can get very sick. Xylitol is in a few other things like chewing gum…so be aware if you have a dog that gets into things at your home. But still try to brush their teeth!! And find no-xylitol toothpaste or don’t even use toothpaste.
