I had a male Basenji that peed like a horse until the day he died at 15 and a half. No matter where he was. And it was kinda nice having a male that wouldn't hike his leg to piss all over things, never marked anything either. Don't complain if your boy doesn't hike to pee.
On the other hand, I had 2 Siberian Husky bitches who were TERRIBLE markers, always tried to get it as high as they could. They were both spayed too. One passed away a few years ago, still have the other, and she never marks anymore.
