How to correct housetraining mistakes with our new adopted puupy?  

You didn't mention how old the puppy was. Don't worry though, your puppy will learn in time. You just have to listen when you think that he is sneaking away to go in the house. We got our dog from a shelter 8 years ago. We are the 3rd owners of him by the time he was 1 yr old. Once in a while he still will go in the house without warning, but most of the time he lets us know when he has to go out. You might try limiting the puppy on where he is allowed to roam in the house, and slowly let him advance his roaming, one room at a time. Good luck with your new puppy, and I hope that he brings you years of happiness.

I have 3 dogs, 2 are potty challenged lol. The one, we took in because the owner wouldn't care for her, I don't think she's ever been an inside dog, the second I got from a pound about 10 years ago, and she's always had anxiety attacks when I left, now she does it in the middle of the night, and the third he's great, only notice he gives he wants to go out is he stares at you lol. Very subtle. Unfortunately because of the 2 pottying on the rug at night, they're outside dogs now, at least until the 2 die. My experience with puppies though, and even my male dog, got him from the pound when he was about 1-2-& not trained very well, make a big deal about going outside. Pick a word to use, like "outside" or "take a break" and everyone always use that word when it's time for him to go out. When he does go, repeat it good boy-outside-good boy and pet him and praise the heck out of him. He'll eventually associate the pottying with outside and the praise. Also, take him to the same spot outside to go whether on a leash or you carry him. He'll also associate the scent with it as well, AND if you're lucky, he'll always use that spot to go instead of leaving land mines around the whole yard :) If he goes in the house, if it's poop pick it up, take him and the poop outside to that "special" area, put the poop there and say "outside" point to it so he can learn that goes out side. Also, I think it's recommended to take them out within 15 minutes of them eating. Just takes time, he's still kinda young, so accidents will happen. At least he'll stay small and you won't have huge logs blocking the doorway when there's accidents in the house :)

My vet told me that it is a good idea to crate train. When the puppy goes to the bathroom allow him so much time out of his crate alone. Then he must go on a leash and be with you at ALL times. When you take him outside you must go with him, and do not come back inside unless he goes. If he does not go then he has to go back into his crate. Do this for about 3 weeks and he should get the hang of it. ALso, feed him on a certain schedule each time. They you will get him regualar enough to know exactly when he will be making a pooo. Take him out during that time as well. Also take them out 20 minutes after they eat or drink. Hope this helps.

Watch him, correct him and make sure - it's done daily so that he gets into the habit of adjusting to your schedules and your ways

sorry i am not having a puppy.

As brutal as it may seem ..if pup poops or wees, rub pup's nose in it and put it outside! They get the message very quickly!

I am going through the same thing, so I sympathize. My puppy is a chiweenie, she was only five weeks old when we got her and much too tiny to walk through the grass, it was all too tall for her so we have to train her for now on puppy pads. She is wetting on the pads but won't poo on them, I'm constantly fighting her on this. I want to take her outside and try the sidewalk, but due to her size she can't go out early in the morning or late at night right now due to the cold, she will easily get sick. I'm just doing everything on a timed basis and rubbing her nose in the poo and trying to catch her in the act so I can put her on the pad in time, not sure what else to do.
