Just a story with personal experience. My moms dog was adopted from a shelter when he was 8mo. He’s a beagle mix, and the sweetest dog there is. However, as every dog that leaves the shelter has to be neutered there wasn’t a choice to neuter him or not. In this picture he is 6 years old and he still looks like a pup, he never matured into his body and has a ton of health issues.
You wouldn’t neuter/spade your teenage kid for being a knuckle head. Buckle up and stay disciplined. Like Alin said be the most interesting and rewarding person in your dogs life. Good gets abundant reward and bad gets corrected.
If you still desire to proceed than please just wait till he fully matures.
