Prostate Inflammation and Abscessation in Dogs

Prostatitis is a bacterial infection of the prostate gland, usually preceded by a bout of cystitis. An abscess of the prostate is evidenced by a pus filled sac that may lead to prostatitis, which is an inflammation of the prostate. This is often the result of a long-standing infection that has gone undetected. Prostatitis is divided into two phases: acute (early), and chronic (later, farther into the disease). 

A sudden onset of bacterial infection in prostate is termed as acute prostatitis while a long-standing infection that has gone undetected is termed as chronic prostatitis. If signs of acute prostatitis are missed and condition not treated, it can lead to chronic prostatitis.

Symptoms associated with acute and chronic prostatitis include:

Sudden (Acute) Prostatitis


Lack of appetite

Straining to defecate

Difficulty urinating


Pain in the abdomen

Bloody discharge from the urethra

Stiff walking pattern

Long-Term (Chronic) Prostatitis
