Please help me out here. All my dog training books say that puppies can't be expected to respond to housetraining before about 12 weeks or so, but our puppy will be just 8 weeks old when he arrives. So what do I do in the meantime? Sometimes I'll be away from the house for up to 4 hours for work. Do I delay housetraining and just have a secure "playpen" area that includes an open crate and potty pads? Or do I start crate training immediately anyway, expecting that he'll just have a lot of accidents? Or is there another solution? Please post!
