As another poster mentioned, its important to be sure they are on the right schedule. As with babies, you need to play with them, feed em', make sure they've pottied, play with them again, then put em' to sleep. During the day while your gone, thats all they do really is sleep. So when you get home, you should make sure your playing with her and keeping her very active until its time to go to bed. Its also good to have a cut-off time for treats/eating so she wont be using the bathroom all during the night. Not sure what kind of crate you have, but I believe its best to have a small crate (one that she can only stand up and turn around in). They are den-like creatures, so having the larger crate doesnt seem to work when trying to crate train. Also, depending on how old she is, she might be crying to use the bathroom. At a young age, they arent able to hold they're bladders all night. So maybe confining her to an xpen with her bed and some peepads might help. Hope you get the answers your looking for
