regular schedule good idea
My daughter & I trained her dog from the time he was a pup. We crate trained him. It took only one time for him to have to lay in his urin & excrement to know that it wasn't a good idea to go to the bathroom where you live. A typical day went this way: As soon as I got up in the morning I'd take him outside to go potty, then I'd feed him & go through my morning routine. I'd take him for a quick walk before going to work, and crate him while we were not in the house. When I got home from work, the first thing I'd do would be let him outside to go; then I'd give him his supper & fix our food. & Just before going to bed he'd get one more walk. When he was a pup we'd crate him while we slept; after he didn't want to go into his "house" (that's what we called the crate) anymore, we just had to reason with him a little bit... unbelievably, he understood & has never given us a problem since.
The thing here though is ROUTINE... once a dog gets a regular routine, they're fine... at night, if I happen to fall asleep in front of the tv my dog will let me know when it's time for his nightly walk because the regular routine is to take him out right after the weather report on the nightly news... you'll hear a little grumble & he'll nudge my foot... LOL he's so spoiled...:) but we love him soooooooo dearly, & he knows it :love:
Good luck with Lilo
