House Training Your Pet
Petfinder
The key to training your dog to eliminate outside (where you want him to) is to prevent accidents and to reward success.
Adult dogs have better bladder and bowel control, and can "hold it" for a longer period of time than puppies. The rule of thumb with puppies is to take their age in months, add one, and that's the number of hours the puppy can "hold it" during the day. (ie; A 4 month old puppy can be expected to be clean for up to 5 hours during the day)
Feed your dog on a schedule (he'll eliminate on a schedule, too).
Keep his diet simple and consistent (avoid table scraps and canned foods; a high quality dry kibble produces the least waste).
Choose an area, about ten square feet, outside, where you wish your dog to go potty.
Take your dog on a leash to the area, pace back and forth (movement promotes movement) and chant an encouraging phrase ("do your business, do your business").
Do this for a maximum 3 minutes:
Try again in an hour; eventually your dog will eliminate appropriately and you can give huge praise and play.
If there is an accident; decrease freedom by 15 minutes for 3 days.
REMEMBER! DO NOT PUNISH ACCIDENTS! IGNORE THEM, AND REWARD SUCCESS!
