Have two enormous snuggle bears here also. They, too, must pee on everything - "leaving pee-mail" for the other neighborhood dogs, we call it. And they both do the 'pee, scraping kick, pose like stallions, and then trot off to the next bush' thing. Have had ZERO issues between the two boys - they established their own hierarchy and they obey it. Which sometimes means that if I want both boys to have a chewy long-term treat, I have to separate them, because Pooka is ALPHA and will hoard everything. They don't fight, at all, but Pooka will march over and steal anything that Nanook has, which leaves Nanook without.
