Some dams have a tendency to lie on their puppies make sure the box has appropriate roll bars inside the box.

有些母狗有躺在自己幼崽上的习惯，因此还要保证在盒子的内部有适当的卷边可供母犬依靠。

Roll bars are spacers about four inches above the box floor that provide the puppies living space between the mother and the box wall should they become trapped.

卷边可以安装在分娩盒内部四英尺高出处，这样就可以在母犬与可能卡住幼犬的墙壁之间隔离出空间供幼犬活动的空间了。
