Hello. This looks like a possible infected hair follicle of sebaceous gland infection. It is probably not dangerous, especially since your dog is still quite young. I would gently clean the area with something like Hibiclens ( available at all pharmacies ) & if it seems to be getting worse, bothering your dog, or begins to ooze, please see your vet as soon as possible. Thanks for using Petco Pet Education Center, formerly Petcoach.
