House breaking older dog

Question
Hello
    I have a 9 year old lab that we have raised from a pup, she has always been an outside dog.  We would like to start bringing her into the house for maybe an hour or two in the evenings while we are home, but in the past we have had a problem with her peeing on the carpet, what would be the best way to break her of this.  Thanks

Answer
I am sure she is careful not to foul the area she spends most of her time outside.  She may not realize that if she went to the door, you would let her out.  Some people hang a bell there for the dog to paw. If
your dog doesn't figure this out, try praising it and putting it out if it
even gets near the door. A stern "Bad dog!" is all the punishment that is
effective, and only when you catch it in the act and are sure you didn't miss
it going to the door. Clean up accidents promptly. I mostly keep the little
puppies out of the carpeted rooms. Still I need the can of carpet foam
sometimes.  First blot up all the urine you can with a dry towel.  Keep moving
it and stepping on it until a fresh area stays dry.  A couple big putty knives
work well on bowel movements.  Just slide one under it while holding it with
the other.  This gets it up with a minimum of pushing it down into the carpet.
This works with even relatively soft ones, vomit, dirt from over turned house
plants, or anything else from solids to thick liquids.  Finish up with a good
shot of carpet foam.  Note, do not let the puppy lick up the carpet foam.
Once the dog is reliably housebroken, your carpet may need a good steam cleaning.
