Prostatitis in Dogs

Prostatitis is the infection of the prostate, which is an organ located below the rectum and is important for the production of seminal fluid. Male dogs that are not neutered are prone to developing prostatitis. The infection of the prostate is often caused by the accumulation of bacteria in the area of the rectum and will cause elimination problems and pain. Antibiotics can treat the condition, but in some cases, there is an underlying condition leading to the development of prostatitis and this will have to be treated.

Causes of a Prostatitis

Prostatitis is a condition that affects only dogs that haven’t been sterilized. However, in rare cases, neutered dogs may also suffer from this condition. The infection is typically caused by the accumulation of bacteria or fungi in the prostate area. The infection may originate in other areas of the reproductive system or the urinary tract and the infectious agents migrate to the prostate as well. In some cases, there are underlying conditions that lead to prostate infections:

  • A cyst or multiple cysts that form on the prostate. These cysts are liquid filled benign growths that are typically harmless, but if they cause recurrent infections, they need to be removed
  • Tumors, which can be benign or malignant growth affecting the prostate. The tumors may originate in the liver or other organs in the area and metastasize in the pancreas
  • An imbalance in the production of hormones
  • The long term administration of antibiotics can disturb the natural balance and result in the occurrence of infections which may affect the prostate as well

Symptoms of Prostatitis in Canines

The prostate is an organ that surrounds the urethra and the intestines of the pet, so the infection of the gland will cause symptoms that are related to the elimination of urine and feces. Typically, an infected prostate gland will be inflamed and this will cause constipation. The dog will also strain to urinate. There may also be other symptoms including:

  • Blood in the urine and in the feces, if the dog can eliminate feces
  • Pus and mucus in the urine and fecal matter
  • Pus or blood filled discharges from the pet’s penis
  • Fever
  • Enlarged abdomen
  • Lethargy
  • Anorexia

In some pets, there will be no symptoms, especially if the infection is not severe.

Diagnosing Prostatitis in Dogs

An analysis of the urine and the feces can establish if there is an infection. A blood test will also show elevated levels of white blood cells, should the dog have an infection. The vet will perform a colonoscopy, if he suspects any underlying conditions such as tumors. Anesthesia is required for this test.

Prostatitis Treatment Options

Prostatitis can be treated with antibiotics. The vet may choose amoxicillin or other more powerful antibiotics. Make sure your dog is not allergic to the prescribed antibiotics. Additional treatment is needed if the dog has an underlying condition.
