Generally speaking, the form of dog cage is not many, most of them are also reasonable, there are trays below, which can easily clean the dog's urine. I want to remind you to observe whether the bottom of the square iron rod dog cage (that is, the bottom of the cage above the plastic tray) is movable and can be taken out and cleaned, because the dog's stool will stick to it, and if it can't be taken out, it will be too troublesome. There is also the larger size of the wire dog cage, usually there is no wheels below, which is very inconvenient, to move up will be very heavy, small size of the wire dog cage is not too hard to lift.
