Maybe, but it works. Seeing your home from a puppy's eyes level will help you spot anything dangerous. Some common houseplants are poisonous. Unplug all small appliances when you're not using them. Inspect your home for any frayed electrical cords that can shock your puppy if he tries to play with them.
Cords hanging from blinds can be deadly.
Your puppy can hang himself if he gets tangled in one of these cords. Cut blind cords, wrap them tightly around a bracket, or tape them tightly to the top of your window. Be certain all doors that lead to the outside shut tightly. Watch windows too. If your puppy is large, he may be able to crawl out of a low window.
