Blue went for his comprehensive exam yesterday. Now when my husband went to pick him up they said his anal glads were rock hard, and needed to be cleansed. So he payed the extra money to have them release everything in there. Is there something we can do to prevent this from happening again, or is this something normal that we will need to take him in for every couple of months? I had never heard of this before, so I'm not sure what to do....
