Counting Off The German Shepherd Potty Stops

At eight weeks old my little guy can hold his bladder just about three hours, so I make a point of making the procession to the potty spot in the yard every three hours.
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 its potty time again and then one last time just before we go to bed.
This is the story of my attempt at German Shepherd potty training about 10 trips outside a day which is fine now but once the snow starts to fall I think night time potty duty may have to be Mikes.
