What is Perianal Fistula in Dogs?

Perianal fistula or anal furunculosis is a serious medical condition characterized by chronic, foul-smelling wounds in the tissues surrounding the anus. The exact cause of perianal fistula in dogs is unknown, but many factors can contribute to the development of this lesion. German shepherds are most commonly affected, but it can also affect other purebred or mixed-breed dogs. Dogs older than 7 years old are at higher risk of suffering from perianal fistulas.

Perianal fistulas are often the result of the contamination of the hair follicles in the perianal area (around the anus) by fecal material and anal sac secretions. This contamination can progress into tissue damage and inflammation. Dogs who suffer from allergic skin disease and low thyroid hormone levels are more prone to developing perianal fistulas. The likelihood of contamination is greater in dogs with hairy tails.

Treatment of Perianal Fistula in Dogs

The treatment of perianal fistulas can be medical or surgical. In most cases, medical treatment consisting of cleaning and disinfecting the affected area is attempted first.
