What about a button she could push that would turn on a light, as a going-out signal? Or get/rig something that *both* rings (for you) and lights up (for her)?
I am interested in trying to teach Russell to ring a bell to go out, but am leery of doing it until he is better established with "holding it", because I don't want to have any larger than necessary a problem with him ringing to go out "just to get outside", you know?
Russell is doing really well. The only times he has had any kind of accident in the house is *occasionally* a little when he's in his crate between his 5:30 a.m. post-breakfast walk and my getting up "for real" at 8 or 9; or if he gets super excited by my husband coming home or by cats chasing each other past him. Mind, he is never unsupervised when loose in the house, and I do take him outside every couple hours or if he looks like he needs it.
We really ended up with THE easiest-to-train dog in the world, with him. I don't get how anyone would ever want to get rid of him! He now sits very reliably (including about 75% automatically when we come to doors or gates and after we go through them), will reliably "come" from up to 100 ft away unless distraction is pretty significant, and the other basic skills (except heel) are doing well too. (I got bored yesterday afternoon and decided to teach "roll over" -- after about 45 minutes off and on working on it, he now rolls over real good
) He does require a good bit more practice at not having his brain fall out big-time when he meets new people or someone walks nearby in the park, but then he IS a puppy still. And he seems pretty happy here, and loves to snuggle with us
He does sit a little funny sometimes. I hope it is not the beginnings of hip problems. But, what can you do <shrug> He is a really, really, really good dog.
