I heard from a friend peanut butter can make a dog sick is that true?
Some health food stores sell peanut butter that use Xylitol as an artificial sweetener. It is safe for humans but very toxic to your dog/cat. It also can be found in some chewing gum, candy, mints, dental hygiene products, and vitamins. Dogs usually get these items by snatching them off the table without your knowledge. As an example, sugar-free Mentos contains Xylitol. Keep an eye for those counter thieves!
