This is another area that should be kept relatively off limits to the four-legged members of your family. Dogs love both the smell and taste of antifreeze, which is deadly in even small amounts. Also, many rat poisons and other pest control products are designed to kill without tasting bad.

Nails, screws, paint, petroleum products, fertilizer, sharp objects, tools, electrical outlets, and things that could be knocked over — like bicycles, motorcycles, ladders, and furniture — are all serious hazards that need to be secured before your puppy can be allowed to roam this area.
