Bad for dogs.

........................One more thing. The vast majority of veterinarians agree that fluoride in tap water and pet supplements is the leading cause of fluorosis, a painful chronic joint and bone disease that can start in puppyhood and often affects many older dogs. There’s no chlorine and harmful fluoride, and they've added all-natural, soothing, energy-enhancing nutrients, natural herbal essence, and a natural flavoring 9 out of 10 dogs simply love.

It's OK for us though dentists swear by it.
