Neutering a male is simple - until late last year, the only dogs I’d ever had have all been males, and they’ve all been neutered. None of them has acted like anything even happened afterward! They didn’t have any stitches either, the incision is so small. The most difficulty I’ve had is keeping them quiet for the week to 10 days afterward they aren’t supposed to be running and jumping so the incision can heal.
You can also combine the neutering with something else that needs to be done, like a good teeth cleaning.
