We have a 1 year old who wakes up every morning about 5am. She seems to wake up to go to the toilet and is then wide awake. We are still leaving a puppy pad down for her as we don't want her to pee on the floor. Any advice on how to get her to sleep longer without waking up to go to the toilet, she does get taken out for a walk around 10:30pm each night and usually does a wee when out on her walk. Thanks for any assistance. .
