Pee marking versus bladder draining
Wasn't sure how to title this thread, but I'm looking for advice. When we are home I let Gunnar in the yard for 5 minutes to an hour a few times a day. He manages his bladder on his own. But when I take him on the road with me (I'm a traveling salesman) I need to let him relieve himself but instead he'd rather pee a bit on every upright thing he can find.
For example, we drove all day, then went to a big park for an evening walk. Gunnar must have peed 50 times in the course of our hour walk. Whatever volume that is.
The next day I walked him around the hotel, commanded "go potty" and he will only sprinkle. I'm sure there is more pee in there but he won't drain his bladder. Can I train him to drain his bladder? If so, how?
