Observe if the structure of the dog cage is reasonable

Overall, there are not many forms of dog cages, and most of them are relatively reasonable. There is a tray underneath, which can facilitate cleaning the dog's urine and urine. I would like to remind you to pay attention to observing whether the bottom of the square iron bar dog cage (i.e. the bottom of the cage on the plastic tray) is movable and can be removed for cleaning, as the dog's feces will stick to it. If it cannot be removed, it will be too troublesome. There are also relatively large wire dog cages, which usually have no wheels underneath, which is very inconvenient. It can be heavy to move, while small wire dog cages do not require too much effort to move.
