Hello Kim - AT his age it is quite possible that one testical is NOT going to drop. The reason ( among others) may be an inguinal hernia. I had one male who presented with the same genetic problem and at age 3 years he was neutered the vet had to go on a scouting expedition to locate, retract & remove that testical. This is not a good trait for breeding and it can be passed on... so if the plan is for pet- I suggets scheduling that appointment any day!
