How should the dog be treated? | This is a chronic problem due to extensive perianal furunculosis and cellulitis.
There is the risk that damage to the anal sacs and/or ducts may lead to chronic fistulous tracts and recurrent infections. If this occurs, surgical removal of the anal sacs may be necessary. |

What is the source of secretions of the anal sac and what is its function? | The walls of the sac are comprised of sebaceous glands and the ducts are lined with numerous epitrichial sweat glands. The anal sac fluid is a mixture of fatty acids, serous secretions, and cellular debris. The function is unknown but is presumed to be part of scent marking/social function. |
