I agree with shais_mom. However if it is laminate or something non-porous there may be some hope.

First thing is to get rid of the puppy pads. Even though the dog is supposed to potty just on them it is still teaching the dog that it is ok to potty in the house.

Second I reccomend a crate. I used one for the first time with Kaige & I'll tell you it was a housebreaking miracle. The best choice I ever made. For a large breed dog as a puppy I reccomend the kind with the divider panel, it allows the cage to grow with the dog. At first keep the area as small as possible. Only barely enough room for the dog to stand, turn & lay down. A dog generally does not like to soil in their sleeping quarters.

Third, have her get some natures miracle or another product that is desinged to elimate ALL orders of urine & feces, not cover them up. NM was studied and it is now known as the best-known enzymatic stain and odor remover on the market. Eliminates urine odors completely with no perfume cover-up odor.

Fourth would be to limit the amount of free roam the puppy has. Perhaps she can gate off a room for the pup when she can not be right there to watch his every move. Or even tie a leash right to her with the dog on the other end. At that age, especially during housebreaking you really need to watch the pup at all times. If you can't that is where the crate comes in mighty handy.

Fifth would be to make sure she is training the right way. Make sure she ALWAYS goes outside with the pup. Do not play, look at or pet the puppy until after he has eliminated. I find that giving the dog a potty command works great (and will come in mghty handy for trips, vet appointments etc...). I tell my dogs to "go potty". Once they potty PRAISE like crazy.
If the dog in known to go outside then goes again soon after you come inside it is best to bring the dog inside then minutes later bring him back out.

Do not punish the dog for eliminating in the house unless you catch him in the act. Even if you catch them seconds later it will do no good, it will only confuse the dog.

Sixth, obedience classes. A basic/puppy class would be great. A reputable trainer will help with basic puppy problems (housebreaking, chewing etc...) they will also teach your dog basic manners, help socialize the pup & help build the bond between dog & owner.

seventh, patience & persistance.

I wish her good luck... maybe she'll be our next new member?
