If your new puppy seems to be pretty edgy or pretty vocal, chances are he/she needs to go outside. They naturally don't want to make a mess in what looks like a nice sleeping or playing area. I found it to be most effective if you have a tie out where the puppy has time to unwind and time to him/herself to take care of business. The puppy will come to the door and naturally want to come back in when he/she is finished. Don't be impatient, they will need a few minutes, it doesn't always happen in the first minute or two, it might take 5-10 minutes. Hopefully this helps.
