Gracie learned the concept very quickly...(she would go to the door and pee at the door, hadn't quite figured out the holding it part
) But by the time she was 12-14 weeks she was going to the door only having the occasional accident....and at 20 weeks she was COMPLETELY potty trained...she whines at the door if I am not paying attention...I had heard they were hard to potty train and was worried but Gracie caught on VERY quickly...Good luck with your little guy
