Okay, so we had hoped to avoid neutering until 1 year of age. Brodie, in the last month, has started lifting his leg and just in say the last 2 weeks has started what I would consider heavier marking. In other words, he is not 'draining the tank' he is saving some for here, some for there. This is only in our yard though, he is not marking at all on walks. He normally does not go on walks as I take him out in our yard before heading out, but this morning, since he saved a bit instead of draining it all, he squatted in the street. This week, he lifted his leg out on the deck. Thank heavens the slider was closed, but what a mess to try and clean urine out of that little track! He and Kooper were on our deck while I mowed the lawn just a bit ago (it is gated) and even though I had taken him out prior to starting to mow, I came back to 3 pee spots - two were on the slider and one on a planter. Kooper does not lift his leg, he squats and so I know for sure it was Brodie. He has also started doing his version of humping a lot more often. He goes up to Kooper, doesn't actually mount him, but will stand to his side or behind him and do a bit of hip rocking. We tell him 'No' and he will stop, but it is becoming more and more common. At what point should we consider neutering earlier than planned or is there a better way to address this stuff?
