we bought the box for transporting our 12 week old puppy over 400 Kilimeter and then also as a box for the home for the first few weeks. Little Toller has tricked the car, his new mistress sat danaben, and the two have met each other. It was a very relaxing ride! After that we have used for a while the box still in the house. But when the little rascal times for a while was alone in there and closed the box, he has also hingekriegt, with the box to wander around the room, because it is so easy. This is obviously not the intention. The box, however, is extremely stable for their light weight and has taken no damage from such games. Also, the folding mechanism (simply fold) has been proven. The carrying case for the box has now become our bag for the dog school and is perfectly suitable as a water-resistant large rubbish bag with shoulder strap and an exterior pocket. Meanwhile, we have a much larger and more stable box for home, so the now 6 months old Toller also has enough space for its withdrawal, but set the box at shorter car trips again after it is in the back seat with belt repeatedly gone bad and He has passed several times in the car. This problem has been solved since then. For transport in a car that goes well on the back seat between the driver seat and the backrest is fixed, for the trunk, the box would certainly not suitable. But for our purposes, the top!
