Mine are all pee pad trained, but, when they go outside to play, they will potty out there. But, we took an 850 mile trip last Christmas with 4 pee pad trained dogs, we have a van, so, we took the back seats out, put their beds back their, the pee pads, water and food, and drove straight through. They hardly even peed at all on the trip up there or back. Think there were 2 pee spots the whole trip |
