Young male does do have the ability of retracting testicles but you should be able to work it down and feel the testicle when the male is standing. A dog's testicles descend through the inguinal canal and this canal usually closes at around 4 months of age so once it is closed the testicles will be stuck either up or down. I do know there are exceptions to that because I have read instances where people have reported their dogs testicles dropping as late as one year.
I also know that stress can cause a male to retract a testicle. I know of 8 month old male that had both testicles down but when he went to his first show he retracted one of his testicles and the judge had a hard time getting it to come down, but luckily it did and not long after that it was never a problem again.
Without actually seeing your male it would be hard to say if he has an actual retained testicle or if, like you said, he just has one smaller than the other which it not that uncommon. My advise would be to take him to your vet and have the vet examine him. If he does have a retained testicle you would definitely want to have him neutered. |
