I have a nine week puppy so she naturally needs to go outside times at night to relieve herself. I'm relieved that shes choosing to go than using her crate as a bathroom but the frequent nighttime trips and her whining when I put her back in the crate are exhausting. I attempted using pads in her playpen. She still wakes up wanting to go outdoors. However night I set up a patch of grass for her. She used it every time without waking me up! While I still woke up a times worrying if she needed to go out if this trend continues I'll be happier and more well rested knowing that shes progressing well with training.
