To help the anal glands to function properly, dogs need to consume the right amounts of fiber. Sadly, due to a lack of good fiber in the average canine diet, many dogs have to have their anal glands expressed manually … meaning the vet or groomer squeezes them by hand to get the fluid out. You know your dog marks his or her — girls do it too! Dogs have two small glands on either side of the anus. These glands fill up with a fluid that has a scent exclusive to each dog. When your dog secretes this fluid during defecation, he spreads his unique signature through his poop. This can lead to chronic infection and, in some extreme cases, conventional vets will surgically remove the glands.
Anal Glands FAQ
Anal Glands FAQ | Best Friends Pet SuperCentre
Your dog's anal glands are two grape-shaped glands located just below the anus to either side. The pheromones they secrete give canines vital information about one another, including health, age, and sex. This explains why dogs sniff each other's rears when they meet and insist on taking a whiff of every poop they pass on their morning walk. Sometimes the fluid in anal glands can build up, causing your dog to lick or bite his anus and "scoot" his bottom around on the floor after or before defecation. This can happen to any breed, though small dogs are particularly prone to anal sac disorders. While the veterinarian will do this for you, it's also possible to save yourself a trip to the vet's office and do it yourself. Remember, though: before attempting this for the first time, do consult a veterinarian, as improper or unnecessary expression can lead to health problems.

The anal glands or anal sacs are small glands near the anus in many mammals , including dogs  and cats. They are paired sacs on either side of the anus between the external and internal sphincter muscles. Sebaceous glands within the lining secrete a liquid that is used for identification of members within a species. These sacs are found in many carnivorans , including wolves ,  bears ,   sea otters  and kinkajous. The anal glands are in the wall of the anal canal.
Examination by a vet or vet nurse is needed and antibiotic treatment may be necessary if infection is present. Manual expression by a vet or vet nurse is needed once impacted. Most dogs are able to empty these glands whilst having a bowel movement or during exercise.
