Anal Sacs (also called “anal glands”) are two small glands just inside your pet’s anus. The material secreted into these glands is thick and foul-smelling. Most animals can empty these glands voluntarily for scent marking or in self-defense (like a skunk might do).
Domestic animals have largely lost their ability to empty these sacs voluntarily. Walking around and normal defecation serves to empty the glands but some animals become unable to empty their glands on their own at all. T he sacs become impacted and uncomfortable. Dogs with impacted anal sacs usually scoot their rear on the ground in an attempt to empty the glands. Some dogs will lick their anal area and other dogs will chase their tails.
