I am not sure who is being trained here but we are getting lots of fresh air! 
I have Paco down to one puppy pad in the house but he almost always goes outside.
Sometimes I missed his cues. Sometimes he just sits and stares at me for a minute to tell me he has to go. If I am busy at the moment I miss his cue and he goes on the puppy pad. The puppy pad is in a corner so I have strung a row of little bells between an end table and the couch. If he goes to the potty pad he has to ring the bells.
Hopefully, with the new bells will give me better signal. For now, I am taking him out every time he rings the bells! I am hoping we can turn this into ring the bell when you want to go potty! We are both learning a new trick!!!
