I have a puppy who is now 11 weeks old and would not let it have run of the house. Lari is a Bichon Frise and she will try to put everything in to her mouth!! I have a large crate and put a training pad at one half Lari will do her business there during the night !! I have only left her for a couple if hours during the day sometimes, but she had been fine and safe. Good luck x
