I would need a bit more information, but given your description above I am concerned about Rocky's anal glands. In healthy dogs, they express on their own, but in some cases they fill up and need assistance in being expressed. Even worse, sometimes they become impacted and infected. This requires antibiotics and medical intervention. In the most severe cases, the anal glands need to be surgically removed. Based on your description I am concerned that his are impacted and infected. I would have a veterinarian examine right away to confirm.
