My dog has managed to break this ceiling within 3 road trips and he has not even bitten broken. But only found out the opening in the middle of a zipper that has this one can nicely cuddle with the driver. On the third day of the zipper was then pulled out. In addition, the ceiling is very smooth coated whereby the dog in each bend back and forth non-stop and no place. So can conclude by saying no recommendation to buy !!!
