We have a young, energetic Shih Tzu we adopted from a shelter. When we had the storm door in, he would crash into it, barking enthusiastically at passersby. We we put the screen in, he did the same thing. It was only a matter of time before he went right through the screen. The dog gate we bought from Wayfair works wonderfully. Our little guard dog still barks, but the screen door is safe now. The gate is easy to move, easy to put into place, and is tall enough so he can't jump over it.
