I was out riding and I take my dog with me. She normally rides in her cage in back, but she wants to ride up front with me. I am nervous that she will want to jump out, I have seen it in other places, but do they make a netting to cover the opening above the door? I have the back window and windshield on it. I am not sure if I want the doors on it, (hot in the summer, great in the fall and winter),they are kind of pricey. I was thinking of something that was easy to install and remove.
