Accidents are inevitable!!! Old fashioned house training methods tell us to grab the puppy, show him the mess and punish him. This is not only unnecessary but harmful. Instead, if you discover an accident, just say "ugh" disgustedly and whisk the puppy out to his proper toilet area. Make sure he cannot see you cleaning up. Some dogs find it rewarding to watch their owner picking up stools or cleaning urine, and often leave another such gift as soon as they can.
To discourage repeat visits, accidents must be cleaned up well enough to completely eliminate odor. After blotting and cleaning as best you can with paper towels, soak the stained area with an enzymatic cleaner. Let it remain on the stain 30 minutes or longer, blot up the liquid, and if still necessary, use regular rug cleaner afterwards. To work properly, the enzyme cleaner must be used before using regular rug cleaner. Vinegar works very well on tile/linoleum floors.
Pick your puppy up and take him outside
-After waking up, even from a short nap
-After playing
-After drinking water
-After prolonged chewing on a toy, etc.
-If he starts sniffing or turning in circles
Gather him up in your arms and take him outside to his spot. Say ‘out’ as you’re going out the door. Choose a word to identify elimination – I like ‘hurry up’. Say your word as the puppy is eliminating. When he’s done tell him he’s a good boy. He will soon associate ‘hurry up’ with the action.
Take him out the same door, to the same spot in the yard, every time. In a few days your pup should automatically head for his proper place after meals or whenever the urge strikes. If it takes longer, be patient, he's a baby.
After this stage of house training, your puppy knows where to go, but not when to go. Do not try to teach self control (the "when" part) until you can be sure he will always head for the door when it's time to go.
Puppies have a strong natural instinct to avoid soiling their own area. If you are consistent and patient, this natural urge for cleanliness makes house training fairly easy.
