As pet parents know, not everything that is healthy for us is good for our furry friends. Herbal Toothpowder Tabs should be kept away from your pets because Xylitol, one of the ingredients beneficial to human oral health, can cause rapid hypoglycemia in pets. Much like grapes, which are nutritious for humans but should not be given to dogs, Xylitol is perfectly healthy and beneficial for us, but because it is processed differently in the bodies of other animals it should never be given to dogs and cats. BOTTOM LINE: Keep out of reach of pets, as Xylitol is poisonous to dogs. And be sure to check with your veterinarian.
