Hi, I just got the Kurgo Skybox for my new Yorkie puppy a couple of weeks ago. So far so good - I tied the strap connected to the carabiner in a big knot so that it doesn't have so much length, because Ziggy's harness has several inches of leeway before the connector at the end. He's about 4 pounds. I stuffed a pillow between the skybox and the passenger door for my own peace of mind since I can't reach that far to make sure he doesn't get stuck trying to climb out. He perches with his paws on top of the pillow and looks out. He also has been sleeping in it pretty nicely once he got used to it. I have his blanket and a towel inside to give it some extra comfort and height. He does like to chew on the straps! I'm still looking for ways to make it completely worry proof as he likes to turn around and I try to keep track of whether he's got himself twisted in the lead. But overall I am very happy with it. It feels sturdy but he is pretty small. I am still looking for a good car harness that will fit him.
