I'm glad you see after reading things on hear that the newspaper idea doesn't work. You are right, as a few have said that's an old school method that is thankfully disappearing.

Keep consistency, and I think crate training is the way to go. If you get them each a crate, they should not use the bathroom in there, cause it's like their bed. It should be just big enough for them to stand, turn, and lay down.

When you take them outside and they go where they are supposed to, throw a praise party, cheer, cuddle, pat, treat, whatever gets the dogs going. If you catch them going in the house (in the act, not after the fact) clap and say no (the clap will startle them), then grab them and run outside and then when they finish going outside praise them the same as if you take them out. They will learn that outside is a happy place to use the bathroom, and inside they get a loud noise and carried outside (never hit them). If you find a mistake in the house, you cannot punish them after the fact, most dogs have a 30 second to 1 minute short term memory when it comes to training, that's why we have to repeat things over and over, so if you do not react within 30 seconds of the accident, they wont know why you are punishing them.

As long as everyone is consistent with this they should start going outside for everyone.

As for the humping, it should be stopped immediately when it happens, a deep voiced "no" should do the trick. Stop interacting with them immediately when it happens, if its no fun (ie interacting with them) they'll loose interest, the "no" reinforces that it's not appropriate.

Best of luck .
