Well, let's see if I can answer some questions as well as Dixieland Dancer. First, Chembear, WELCOME! It's a fun and cool site to learn all sorts of stuff about your dog and your interaction with her. One thing I did not see in your posts was a crate. Does she have one? If not, it might be worth the time and expense to get one before you move. It will be HER room (no children inside, please) and would be a good thing to have for the move. Once she gets acclimated to it, she can ride in it on the move and you can make frequent stops as Dixieland Dancer suggested. Are you planning to stop at a motel on the way? They'll be more inclined to allow her to stay in the room if you have a crate. Otherwise, they might not allow her inside. It is also a good way to help break that running around when you get home. It is difficult for a 5 year old to avoid a Llewellyn Setter/Border Collie mix simply due to size (unless the child is very tall). Thus, that child will lose almost all the "ignore" games you might come up with. Also, it will allow her to be somewhere where you aren't and allow you to do whatever you need to without her underfoot. I don't ordinarily recommend the wire crates, but in this case, it might be the better option. That way, she can watch you from her "room" and be less anxious about being separated from you.

As for Scout, get that dog into flyball!! Really, it is better to learn to control the playing -- you, not her. When you are about ready to go inside, take the ball and tell her to potty (go potty, whatever the command you want to use). Take her to her spot and just plan to be there a while. She should receive one command and then be ignored until she responds as requested. Then, a toss of the ball toward the house and lots of praise and inside you go. I have always been one to let the dogs out on a tie-out if there's no fence or just out if there is a fence and they don't get back in until I'm sure (either by observance or after a good while) they've gone. I'm still having some problem with my 1 year old Jack Russell Terrier -- she likes to go first and request out after. I'm getting better at reading her, but we're still working on it. If necessary, put Scout in her crate for about 15 minutes when you first come back inside and then run her out to potty before she gets freedom again. Dixieland Dancer has another thing I think you need to consider -- a consistent schedule. I'm sure they covered that at PetsMart, but when you know something is going in (food, water, treats, etc.) you have a fair idea of when it's going to come out and you can plan for that. Mine go out before breakfast and I offer about 20 minutes after. If they don't go out, Lys (the JRT) goes into her crate and Shiloh (JRT cross) gets to sleep on my bed and I go off to work. Then, when I get home Shiloh goes out on the tie-out and when she gets done, Lys goes out, but does not come out of her crate until I'm ready to put her out. Usually, Shiloh likes to go out again after Lys, just to hang out and watch the neighborhood. No big deal. Still, we have a fairly consistent schedule and the girls can pretty well accomodate it. The only thing that ruins it is heavy rain -- Shiloh HATES rain and will hold her potty session until the rain goes away or at least slackens a LOT.

Anyway, I hope that helps some. Email me if I can be more help or more specific, or, I'll check back and see what's happening here.
