Received my fundle and immediately put it to use walking the trails near me. My 9 pound maltese, Nicky, loves it. He wanted to stay in it after I took it off and set it down (with him in it). I got the large because he is so close to the upper limits for the standard size, but, he would have been equally comfortable in the standard size. We will use the extra space in his large fundle this winter with a fuzzy blanket to keep him warm. It is well made and I intend to get another one in the spring with the mesh sides for ventilation. I couldn't recommend it more.
