Yes, be careful what you wish for, Ollie will cock his leg over every errant leaf, piece of rubbish, bird poo etc, and we have had very embarrassing moments of him peeing on other dogs, peoples shoes or back of their legs, boys jumpers left as goal posts and abandoned jackets of park staff.
We have to drag him past park benches and shop entrances to try to ensure he doesn't go. Thought this would lessen after neutering but nope.
