Puppy potty training

Okay my puppies well not puppies any more they are 2 and 3 and I cant get them potty trained is there any way I can do this at there age because they have come acustomed to going in the house please help!!!
Thx

put newspaper down and lock them in the bathroom. Every once in awhile take them outside to go potty. If they do go pee outside give them a treat. If they pee in the bathroom, don't clean it up just make them stay in there.

Or you can practice taking them out the same time everyday. if they use the bathroom praise them for it if they use it inside tell them no. if you see them doing quickly say no. then if they stop take them outside and let them use it then praise a lot!!! this worked with are german sheperd who is now as big as me and still inside!!!
