Well first off, using the pads in the house is only going to let the dog as it gets older that its ok to use the bathroom in the outside.. and most of the time you need to allow more than that time for them to do there thing, they won't more than likely just automatically go outside due there duties and then want to come back in side that could also be a part of why its not going outside very much…

OK…. When your dog goes to the looo (on the floor) put its head to were she peed and say NO! then bring her to the newspaper/ grass whatever you want and say good girl…

Hi,

To jumpstart the process, place a paper towel soaked in your pup's urine (and/or a piece of his feces) in the potty pads. Or, use one of the commercially available products meant to entice dogs to eliminate in a specific area. This will give your dog the idea that this is the place to go.
