She does know the speak command, and has for years. Although most of the time instead of barking she sneezes when we tell her to speak.
Covering the windows is not that easy. Its only glass bricks on either side of the door. I do have a plant on one side, but the way the glass bricks are, the light reflects all the way to the top.
We use hand signals with all of her commands, so that part will be esay. But how do I get her attention when shes barking like crazy? I've noticed that now she runs down the hall while barking. Probably because that's where my mom always is at her house.
Thanks for the suggestions Sandi. I will see what I can come up with that works for us. And Bruce will agree to try.
