One of mine had it , too , while growing up , no real infection , but bald , reddishscappy at times and unsightly - as I had heard of this before ( and the " stud dog tail " which is the same gland involved _ I didn't do anything ( perhaps some calendula tincture to keep it clean , you could alo use Befedo ointment if you can get it - I get it from Germany ) and over the months ( after the first heat ) it went away by it's own . Have seen those bald spots in quite a few adolescent deerhounds meanwhile - reminding me of akne in puberty....
