I hear you. We went through the infected scrotum when Grim has his neuter due to enlarged prostate at 8. It is a lot harder on a dog who has had them removed after they have been fully developed. Grim was so patient he took to the draining like a trooper but I could tell it really hurt. I am certain Beau would take someone's hand off for the same process.
If, for some reason, Beau ever winds up neutered, I am going to demand pain killers and antibiotics before he goes back. So sorry you went through this.
