My coonhound is going on 5 months old now and still hasn't dropped his testicles. I'm not showing him or breeding him. He's just a pet. He will be neutered come 6-8mos old. I've checked a few times, had a dogshow friend check. nothin. No sign of anything at all. Charlie is going to the vet soon for his rabiese shot. Should I have the vet check if anything is wrong?
