This might seem like a never ending battle, but with a bit of information into your puppy's psychology and these proven tips, your pup will learn quickly!
Select the site
Before your puppy enters the house, introduce him to specific area of your yard you've designated as his or hers. He or She will soon associate it with bathroom breaks.
Visit it often
It's best to take your puppy outside about every hour as well as upon walking, after playing and feeding and before going to bed. In addition, be alert to signals like sniffing and circling that may indicate he has to go.
Use the crate
When you can't be there, crate your puppy. Your puppy respects his new "den" and will avoid soiling it. If you purchase a crate large enough to accommodate his adult size, you can partition off part of the crate so he won't go in a corner of it.
Correct him kindly
Accidents will happen. Remember that shouting, scolding, and serve no purpose and will only confuse your puppy. Even if you catch him in mid act, simply say "NO!" and immediately take him outside.
Praise him/her
Lavish praise on your dog each time he goes outside in his assigned spot. Speak in a upbeat voice, smile and reward him with treats after he does his business outside.
