Hiking.        Otis was neutered at 6 1/2 months.  He was 1 when I got Oliver.  Oliver was neutered at 4 months.  He may not have lifted, but he followed his brother around outside and had to emmulate his big bro, so he does too!  I think it can definately be a learned behavior because my best friends neutered male only lifts his leg when he and my Otis are together! It's like he has to "be cool" like the other guys.  Peer Pressure to hike!!!
