My positive based trainer has a theory that says that do not let dogs look out the window because it is like teasing them and they do get frustrated. I used to let Pao look out the window, watching squirrels, people passed by and overtime, he did get more aggressive but I couldn't pinpoint what caused the change. So now, all windows closed with curtain including the sliding glass door facing the backyard. No more squirrels and bunny watching. |
