Anal sac disease

Anal sac disease

Anal sac disease is very common in dogs. The sacs frequently become impacted, usually due to inflammation of the ducts. The secretion within the impacted sacs will thicken and the sacs will become swollen and distended. Common signs of the need for an anal gland expression is a dog scooting his bottom along the ground. If you notice this, reach out to your trusted Vetted vets for easy treatment.


Inflamed anal sacs make it painful for your dog to pass feces. The secreted material within the anal sacs is an ideal medium for bacterial growth, allowing abscesses to form. The abscess will appear as a painful, red, hot swelling on one or both sides of the anus. If the abscess bursts, it will release a quantity of greenish yellow or bloody pus. If left untreated, the infection can quickly spread and cause severe damage to the anus and rectum.


The hallmark of impacted anal sacs is a dog scooting his bottom along the ground. Other symptoms include biting or licking the anal area. A vet can manually express full anal sacs, but in severe cases, the sacs may be surgically removed.
