i am getting ready to get a bigger crate for my gsd puppy. i plan to start potty training her using this crate as well. since it is starting to heat up here, i am going to bring her inside from the patio. here's my question. do i lay newspaper on the side i want her to use the bathroom on or just use the pan underneath and put the paper there? also, do i need to put anything in there for her to lay on? it would seem uncomfortable with just the wire.
