The transport box Karlie makes us their services as a dog bed at home and away. We use them for our beagle who fits in well, but probably not centimeters longer. But for larger dogs it is definitely too small. It is easy and quick to set up and just as easily collapsed again and put away in the chic bag. Quality and workmanship are very good, the box holds far too little destruction attempts of Beagles from. Qualitatively they dominated our second box (in the same price range) by far. Two sides and the roof can be opened, the "inlay" can be removed for washing.
All in all a good investment and a good, lightweight dog box.
