I recently moved into a townhouse that my dad owns, he's renting it to me since he moved to Hawaii. While he settles in, I agreed to watch his animals until he's able to have them flown there. His dog, an Australian Shepard/Pointer mix, has always been a super friendly and loving dog. She's about 4 and they had her potty pad trained. I however am trying to get her into going outside and waiting until someone is home/awake to do so. My dog (a 5 year old Neapolitan Mastiff) is trained, so I've been having her try to lead by example, but it isn't working. We've had her for a little over a month with us, and nearly every morning, we wake up to her "messes" even though we take her out right before we go to sleep and don't leave food out overnight for her to eat. It's even gotten to the point to where we'll go out shopping and come home to her "messes". I'm wondering if it's merely her having to go or some kind of informal protest to something. It's at the point to where something has to be done, such as sleeping in a bedded kennel or in our backyard. I'm not sure if these are the best solutions or what exactly to do, but that's why I'm posting here. Any information, ideas, or personal experience is greatly appreciated! Thank you!
