Ugh, I agree with all these posts!! I have an 8 month old yorkie who is very smart and has known to go to the door for a long long time now, but if you don't get her outside when she is at the door she will have an accident at the front door. I'm always curious as to when they learn that they need to hold it for little while, but I guess when you gotta go you gotta go. I would say Em is 99% trained, maybe an accident every 2 weeks, and it's only a poo-poo accident. I find that I have to take her out when I am home about every 2 hours to pee, which isn't too bad but she hasn't had a pee-pee accident in a very long time.
I am getting a little nervous though because I am moving into a new apartment Aug. 12th which is going to throw her off, plus my roommate has a little yorkie too. Emmy has been use to being an only dog since I have had her, but plays well with others. Hopefully, she will be 100% trained soon enough!!
I know how frustrating it is, we are all in the same boat, but one day I think they will catch on fully!!
