Can you train a signal to go outside?
Our 6 month old Boston Terrier puppy hasn't had an accident in the house in over a month. I know she's not housebroken yet. And that the only reason that there hasn't been an accident is because have been taking her out like clockwork. Of course when she goes potty outside we praise her much and give her a treat. (Which of course she loves and responds to happily.)
We do want to start teaching her to signal when she needs to go. Obviously as she has gotten older she holds it longer and it seems like the constant outside-inside thing isn't needed as much.
Anyone trained their dog a signal to go outside? Ideas and references are greatly needed and appreciated!
