My dogs do things like that all the time if we leave them home alone they will pull papers off the computer desk and rip them up or,Get into the garbage,and the thing of instead of scolding i do not mean hit them byt a stern "That's Bad" by giving them treats only makes them think they have done something right when really they havent.When i took my guys to Obedience i switched to a different one,because she was all about treats,training them fine but when they have already learned what to do or how to do it,they should do on command and not do it jus for a treat.Just like my Border Collie she is in trials and i cannot be out in the field with her giving her treats all through her steps.It just dont work that way.
Dont get me wrong my guys always have treats,bones toys,all the time but im i guess different with my dogs then you are yours that is why it is good hearing different ways and techniques because we all do things differently .When your dogs pees on the bed ,you know what she listens too and reacts to different tones of your voice you will just have to see what works for her best.
