DebraDownSouth, thanks so much for the links! And great idea involving kids in her training.
Looks like she's settling down a bit, no accidents yesterday and keeps herself busy by chewing on the bones and toys. We take 2 long walks (about an hour each) per day and go outside in every couple of hours at least for 5-15 minutes. So for a 4 year old dog that seems to be enough physical exercise, right?
As for the crate, I don't trust her yet. Not a fan of a dog in my bed, and she actually likes her crate. It's her spot, she goes there to take a nap, and late evenings, when she's ready for the night, she curls up there as well. Before getting her I wasn't sure if I wanted to use the crate at all but it seems to be working out for her. As for the bathroom incident... that was only an emergency solution for one night and she obviously didn't respond well:)
