Our male mix, Max, was VERY good at killing the grass. He was neutered around the age of 7 months so never did realize he was supposed to heist his leg until he was probably 5 or 6 yrs old.

I have to admit, it was VERY nice. I grew up around male cowdogs and they peed on anything and everything. NONE were ever neutered. So, when he'd go, it was all in one spot. Was always fighting those dead patches of lawn. Now have 2 females.....
We did buy Max some pills (don't remember what they're called at the moment) but never did notice any big difference. Don't think hubby gave them to him every day.
