Well, I can say my dog who will be two is 100% house trained and has been since about 9 months old, I have to say that she never has been able to " tell" me she needs to go out, I kind of just know by her actions. She will sometimes sit and stare at me, jump up and keep giving me kisses. No Bell ever worked for me either, she wont bark or scratch the door so I will keep an eye on this thread.
For me its just my daily routine, up at 6 outside, quick pee, back in the house she eat breakfast.. around 9 am we go for a walk or go out in the yard and play ball, she will poop then ( somedays) , throughout the rest of the day I take her out every 2 hours or so, she eats dinner at 4 and we go for a walk every night at 7 , she always poops on that walk...
I think I have seen this by many yorkie people, they just sort of " know" when their dogs have to " go"
