Most puppies like to root through the contents. Make sure the lids are on tight. Some puppies are capable of opening cabinet doors, especially those that are ajar. If you keep bleach, detergent or poisons in these cabinets either move them or put a childproof lock on the cabinet. Keep toilet lids closed, or better yet, keep your bathroom door closed.
Some puppies love to get a hold of toilet paper and either shred it or run down the hall with it.
Check your yard, fence and gate and make sure that your puppy can not escape. Always be on the look out for loose dirt around the fence that might be an indication your puppy is trying to dig his way out. Remember, house training takes time. If you need to leave your puppy alone during the day or for any extended period you need to crate train your dog. Before bringing your new puppy home, select a veterinarian and set up an appointment for a checkup.
