For cleaning the cage, you can also use white household vinager diluted with water, that takes even cat pee odor away!!!!! I dont know how you feed or water her, but maybe make sure she does not get fed before crating, at least so she has time to produce whats going to come out before she goes in there, and the water, a lot of puppies are social drinkers, dont take me wrong I am not suggesting to dehydrate you pup, but maybe monitor how much and when she drinks, and later on in the eve. take the water away, give her a good watering and then let her get that out of her system. But my also, make an app. with your vet. she may have a bladder infection. Good Luck and keep us posted
