Anal sac disease is caused by clogging or infection of glands called anal sacs located on each side of the anus. It is the most common disease of the anal region in dogs. The anal sacs are related to the scent glands in skunks and produce a small amount of foul-smelling liquid.
Back to Blog. Perineal hernias are located in the left or right perineal region. They occur secondary to weakness and seperation of the pelvic diaphragm.

A perineal rupture sometimes called a perineal hernia is a weakness or separation of the muscles of the pelvic diaphragm.
A perineal hernia is a condition seen in dogs and cats in which the pelvic diaphragm becomes weakened. This results in displacement of pelvic and abdominal organs rectum, prostate, bladder, or fat into the region surrounding the anus. The cause of this condition is not completely understood.
The pelvic floor supports the rectum and keeps the abdominal contents in their normal positions. When the muscular diaphragm is weakened, it may rupture, allowing organs to become entrapped in the hernia. Perineal hernias exhibit as a swelling adjacent to the rectum and most commonly occurs in older unneutered dogs.
Anal sac disease is the most common disease entity of the anal region in dogs. Small breeds are predisposed; large or giant breeds are rarely affected. In cats, the most common form of anal sac disease is impaction.
Q: Floyd, our 8-year-old, unneutered Boston terrier, suddenly developed a large swelling on one side of his anus, and he strains to move his bowels. Is this an impacted anal sac? Regardless, Floyd should see his veterinarian immediately.
Knowledge of anatomy of pelvic diaphragm is essential. Clearly identify anatomic structures to be sutured. Examine hernia closure carefully for defects.
Your dog has a pelvic floor, same as you do. These are the muscles between his anus and genitals that support the organs in his lower body. A rupture in these muscles can lead to a perineal hernia — this is when the organs protrude through the rupture, appearing as a swollen area between his tail and scrotum.
