In truth it's safest to assume that most things are dangerous and tidy everything out of the puppy's reach. This is because even non-toxic items can be chewed, swallowed, and form a blockage in the gut. However, be especially vigilant about putting household cleaners out of paw's reach, as a Lab puppy would love to chew on the plastic bottle and then possibly puncture it with his teeth. Lock all medications away in a safe cabinet. Also, be aware that human foods such as raisins, grapes, garlic, xylitol, and chocolate are toxic to dogs and must be avoided. If in doubt, check before offering any new food to your puppy.
