Counting Off The Yorkshire Terrier Potty Stops

Every three hours it is up and to the yard to go to the potty. Why? Because at eight weeks of age that is just about the maximum time the little baby can go without going to the bathroom.
So, we get up during the night every three to four hours. Then first thing in the morning we go out, after breakfast we go again, then every three hours throughout the day.
If he takes a nap during the day (which of course he does a lot because puppies are growing so much they need a ton of rest) we go right out upon waking up. After dinner it's potty time again and then one last time just before we go to bed.
Thus is the way the life of a Yorkshire Terrier potty training novice. We make about 10 trips outside a day which is fine now, but what about when the snow starts falling? I think, when it snows I'll have to make night time potty duty become a Mike thing.
