Foods you should never feed your dog

What human food can dogs eat is just as important to know as what not to feed fido. You know that grapes and raisins are off the menu, but so are onions, garlic, avocado, and anything containing the sugar substitute xylitol, warns both Dr. Ryan and Dr. Hohenhaus.

Dogs may go nuts for peanut butter, but check the label—some brands are sweetened with xylitol. Both doctors also advise that human food that is not a specific part of your dog’s daily food regimen should not take up more than 10 percent of their daily diet.
