i agree with the keep her in the house idea. 100% solution. If you cant be outside to supervise, the dog isnt outside either. You let them out only long enough to do their business and then bring them back in. my dogs get a maximum of 5 minutes to do their business before they're called back in. (we're also supposed to NEVER have them in the yard unsupervised to begin with anyway. Sorry once potty trained, i'm not standing outside in my PJs dead of winter freezing MY butt off waiting for them to pee and poo!). FYI the poop in the hole thing, doesnt always work. Some dogs will dig right on through it.
