- Wait while he sniffs around – refrain from petting him or playing with him just yet, because you don’t want him to forge an association between this area and games. he has to learn that this part of the yard is for toilet breaks only.

- When he begins to relieve himself, say the phrase you want him to associate with toilet breaks: “Go pee” or “potty time” or whatever works for you. It’s best if that phrase is short and easily recognizable – and use the same voice inflection each time, too (so that your dog can easily memorize the meaning of the phrase.)

When you take him inside the house, the house training regime you’ve decided upon should start immediately.

I recommend getting the carpet professionally cleaned - there are many companies that have special Pet Stain and Odor Removal packages. Once you do that, just give him a reminder lesson on house training and he should be just fine.
