Tucker is 5.5 months old, neutered at 4 months old, he is outside trained, started marking and cocking his leg to pee around 2 weeks before he was fixed. He never marked in the house but he would "mark" where my female peed outside. She would pee, he would pee over the top of it after he would of already gone. That all stopped along with the constant humping about a week after he was nuetered. He definitly was a early starter.
