Anal sacculitis

From Dog

Anal sacculitis is an inflammatory disease of the anal glands in dogs.

The anal sacs are paired cutaneous anal diverticula that are lined by cornified, stratified squamous epithelium, and located within the ventrolateral perianal region. Located intimately with the rectum, they are easily contaminated with fecal bacteria.

Affected dogs usually show symptoms of perianal pain, with scooting and licking of the region. Secondary pyotraumatic dermatitis may also be present.

Secondary bacterial infections are common due to fecal staining and can rapidly deteriorate if no managed effectively.

There are a number of causes of anal sacculitis, which must be addressed according to the underlying etiology:

Manual emptying of the glands is usually required to remove any inspissated or purulent contents of the anal glands. In chronic cases, anal sacculectomy is indicated[3].

Broad-spectrum antimicrobials are usually indicated, with amoxycillin/clavulanate[4] or enrofloxacin indicated in most cases.
