I nuetered my last males at 12 weeks. Jackson was also nuetered at 12 weeks. The first boy squatted all his life. The second (Hoot) lifts his leg and marks all the time. Hoot is also more aggressive and bolder then the other two.
I have also heard that nuetering that young causes more more growth and a bigger dog (the theory being that energy not wasted on hormonal development goes into mass). Hoot is one of the tallest Aussies I have ever seen and Jackson is a pretty tall 27".
These are only my own observations on a pretty small number of dogs. I think that the individual dogs' genetics and personality probably plays a part too.
