Anal Sac

Anal glands are present on each side of the anus in the 4 and 8 o’clock positions. These scent glands empty their secretion during defecation. Anal sac disease (ASD) results when these glands are unable to empty themselves due to reasons such as skin inflammation, obesity, diarrhea, and tumors. Scooting, licking, pain, and foul-smelling discharge are the common symptoms of ASD.
