I am sorry Bailey is not feeling well. I would recommend taking him to a veterinarian to have the rectum area examine. A blood filled sac is never considered normal and in an older patient could be many things. An infection, trauma, cancers and non cancerous masses can occur around the rectum area.

    Poor Bailey! The blood filled sacs that you are seeing could be infected anal glands, or benign or malignant masses. Regardless of the cause, Bailey needs to go to his vet for evaluation. If anal gland infection/inflammation are the problem, your vet will be able to perform a rectal exam to empty the glands and start any necessary antibiotics or anti-inflammatory medications. If masses are more suspected, samples may need to be taken with a needle to determine the cause of these lesions. Until you can get to the vet, be sure to keep an e-collar (cone) on Bailey to prevent him from licking his hind end excessively, as this could make matters much worse. I hope that all goes well!
