I know, so many posts about potty training, lol. But here goes

. My 16wk old yorkie is pretty much potty trained except that he really only tells us he needs to go out when he has to poo. If he just has to pee then sometimes he tells us and other times he just goes on the carpet

. We just added the bells to the door and sometimes he uses them and sometimes not. Does anyone have any tips on how to get him to tell us that he has to go pee? Also i'm not sure if it has anything to do with it being wet outside as it has rained a lot lately. Because before he would more often than not say he has to go outside even if it was just to pee.
Thanks!!!
