I'm sorry to hear that you're having problems with Scooter. Is there some kind of a test that the vet can do that will test his hormonal levels? I've never had this problem. My Starr had both of his testicles still inside of him and then one of them finally descended but the other one was way up inside of him and it was also removed. Maybe the vet could do an ultrasound to see if he see's anything that looks suspicious. Good luck and please continue to keep us updated about him.
