I appreciate the additional advice, although there is plenty of research out there that negates the possible behavioral benefits of having a dog neutered.
Having the dog put under alone is a slight risk. It's not exactly common for a dog to pass away after having local anesthesia, but it happens. There are health risks having a dog neutered as well as leaving them intact.
I'm not going to get into a lengthy debate over this, but I'm not unfamiliar with this topic. I created the thread to pinpoint the issue with recent anxiety. If the DAP is effective then I won't have any issues. He's a perfect dog outside of that one isolated problem. I would consider neutering if it was a 100% certainty that it would rid him of his increased anxiety. Although no one can be certain.
Now if he were mounting everyone in sight and creating serious frequent problems, I'd have him neutered immediately.
As already said, nothing will be with 100% certainty that neutering him will make a total difference… you are the only one that can make that decision... however that said, why would you want to even expose him to the possibles?, if you have no intention of ever breeding him?...and bring into the conversation about cancer that is a concern in male dogs?.. I well understand the difference with the US and our decisions to neuter compared to the thoughts from overseas... however there is nothing in life that can be considered 100%.
