Good morning! our male bun, Tucker, who will be 15 w.o. On Monday, 3/25, has been causing havoc! He has been going after our Yorkie (male, “Ollie”, 10 yo. 13 lbs) and basically terrorizing him to the point that Ollie doesn’t even want to come in the room if Tucker is roaming around. We were told we had to wait until he was 20 weeks before neutering. In addition to terrorizing Ollie, he has been peeing everywhere (not spraying). He sleeps in an extra large crate and then stays in a 15-18sf playpen where he is free to roam in a room that is 540sf so boredom and exercise is not the issue. Our dog comes first but we don’t want to be unfair to Tucker either. A few questions: Will these issues (humping and peeing) pass after he is neutered? Is it typical to wait until they are 20 weeks (we can feel his testicles) to neuter? If so, is there anything we can do in the meantime to keep everyone happy? Thanks, everyone!
