They both do this? How often are you taking them outside to do their business? If it's both of them, then that makes me think it's more behavior than medical…and this can be trained. You may have to limit their space in house and only give them a certain amount of time before going back in the crate to break this habit. If it's not UTI related and you go back to basic training, it may help. What is their schedule during the day/night like?
