Can you go work at your friend's house during the day and work on potty training there? You'd be more able to take the dog out to potty at home at night, when it's dark. That will be a smart dog and the thing about smart dogs is, they not only learn what you want them too easily, they learn what you don't want them to too . If you teach it to pee on pee pads now, you might have a hard time unteaching later. I don't know Dingos, but I know Heelers and they want to PLEASE YOU and do their job, if the puppy thinks it's job is to pee on a pad in the house, it may be determined to do so later. I've had a very hard time undoing "accidental" training with our heeler mix.
