Sounds like an anal gland to me QMC. They can be bothersome. I think it was onster's Onnie who had issues last year. May have been Bunduk. How have Milo's poops been lately? Soft and smushy or firm? I believe if the poop is not firm enough that is sometimes when anal glands don't get expressed. Or maybe one of his is blocked. Better to have it checked for your piece of mind.
