This video shows anal sac clearing. Viewer discretion is advised.  

This video educates the pet owners that anal sac impaction and infection is likely to be the cause of back area biting by the dog and not just skin disease (hot spot).

A smelly back area in this poodle was due to the poodle biting and infection of the skin. Only the right side of the back area is seen. The right anal sac is impacted - blackish secretion is expressed. 

If the anal sacs are not easily expressed via manual expression, in rare cases, the forefinger is used to express the sacs (digital expression). Many owners need to be educated on the need for digital expression if this method is necessary.
