It certainly did!
The key is to do what you know must, try and do what you should, and sometimes do something just for fun. We're still working on solid recalls and housetraining, but they're doing great on leash walking and, as a result, get to go out with me more often.
I got my boys at 8 weeks. I'm convinced they should have stayed until 10 weeks, but that wasn't an option.
The confinement is key. I fed them in their pen, played with them in their pen, treated them EVERY time they entered the pen on their own (still do), only give them new toys in the pen or in the car (as they don't like the car). What I suggest doing is to feed the dog no less than 5 hours before bed and cut water 2 hours before last walk which should be immediately before bed. It can help to move the crate to the same level as the bed so the pup can see you at all times. It's also a good idea if you have a/c or cold drafts near the floor. Set your alarm for exactly 4 hours after the last walk, then take your pup out. Be patient. They usually need to walk around a bit to stimulate bowel movements. My guys could go as long as 10-12 minutes outside before needing to poop though it was rarely that long. Praise lavishly and give a small non-salty treat. Four hours later, get up and repeat immediately. Offer water at that time along with breakfast.
Now I did that just for a week because my vet advised me not to withold water for too long. If they had to pee in the newspaper box, they did so. They were on newspaper at the breeder's so it was a substrate they associate with eliminating. That was great for me and it meant they didn't have to walk or sleep in their own poop. Pretty quickly they started making noises when they had to go and, even it was the middle of the night, I'd dash over, grab the pup, and put him outside immediately because young pups usually don't know they have to go until right when they need to do it. Grab the pup and don't put him down until he's someplace outside. I'd drop my guys on the ground right outside the door and then put my coat and shoes on while watching him through the door window.
Getting sleep was the key. I've raised other dogs before but never two at once and just going back to my instincts and knowing what works worked for me. They're now 18 weeks old and are doing very well. They do have accidents indoors if they've been playing very roughly and, "forget," they need to go and I admit there are times they've barked and I didn't realize it was an, "I need to go outside," bark. The good news is they will sleep through the night now and if for some reason they need to go in the middle of the night they will yelp to wake me and they've been doing that consistently since 13 weeks. They even don't mind if I sleep in a little some days.
I've read a pile of how-to books and received some excellent advice here at Chazhound. Not everyone agrees how to do everything, but like I said, to be a good owner you have to do what you need to keep your act together. That's what I did and it worked. YMMV.
