Help! Hair rings?

I have a 5 month old male chinchilla named Wallace. Today I put in a new wood bridge for him so he could crawl under, chew and play with. He turned onto his back and I noticed that he had 2-3 small itty bitty dots on his wee-wee. I just got him a couple of weeks ago from the pet store (I couldn't find any breeders that were close). I'm just wondering if male chinchilla's at the age of 5 months are able to have hair rings? If they can I'll take him to the vet to get it checked out since he's my first chinchilla. :O
