What are Getting Swollen Testicles?

Testicles (also called testes or gonads) on a dog are the male sex glands which are located behind the penis.  When they are swollen, they are enlarged, more firm, sometimes discolored and frequently very painful. This condition in dogs is called orchitis (or epididymitis) and there are several reasons for it:

  • Trauma
  • Infection
  • Testicular torsion
  • Testicular neoplasia
  • Canine brucellosis
  • Scrotal hernia

Why Getting Swollen Testicles Occurs in Dogs

Swollen testicles can be a very painful experience for your male canine and, if left untreated, this condition can be dangerous for him.   Here is why:

Trauma

This can be any blunt or penetrating injury to the testicles or scrotum. The penetrating wound can open up an opportunity for infections to develop. It is possible for trauma to cause an immune-mediated inflammation (or orchitis) and the body’s own immune system then turns on itself and causes inflammation and testicular damage.

Infection

This can include bacterial organisms, fungal organisms or viral organisms which find their way into the testicles.  These infections can come up from the urinary system or from the prostate.

Testicular Torsion

This is a twisting of the testicle on its spermatic cord.  This is relatively uncommon in dogs but, when it does occur, it is very painful.

Testicular Neoplasia

Testicular neoplasia is a common malady in male dogs as they age. There are three which normally are found: Sertoli cell tumor, Seminoma, and Leydig (interstitial) cell tumor. Metastasis is not common.

Canine Brucellosis

Brucellosis is a systemic bacterial infection which shows up in your male dog as epididymitis, orchitis, prostatitis, testicular atrophy and infertility. It is very hard to treat successfully.

Scrotal Hernia

A scrotal hernia is a condition in which part of the abdomen moves into the scrotum. This inguinal hernia is treatable by surgery.

What to do if your Dog is Getting Swollen Testicles

If you notice that your male dog’s testicles appear to be enlarged or discolored, an examination is in order.  If you are able to examine him, you need to look for any obvious wounds on either or both of the testicles of your pet. 

Veterinary medical assistance is necessary as soon as possible for any of the possible reasons for the occurrence of swollen testicles in your dog.  Infections will need to be treated, masses will need to be investigated and potentially removed or repaired and castrations may be required to assure the safety of your pet. All of the potential causes for swollen testicles are serious enough that your pet needs medical assistance sooner rather than later to avoid permanent injury.

Prevention of Getting Swollen Testicles

When it comes to prevention of swollen testicles, there really aren’t many things a pet owner can do to prevent some of the causes from afflicting their pet.  

The statistics report that about half of unneutered dogs contract testicular cancer.  The only true way to prevent testicular cancer in your dog is to have him neutered, taking away the testicles where the cancer can develop. At the very least, if your pet is not neutered, be sure avail him of regular examinations of the testicles by your veterinarian at every opportunity that you can. If cancer develops, castration is the only treatment.

Infections in the urinary tract and prostate can be difficult to prevent, since the prostate goes through some changes of its own as it ages and urinary tract infections will occur due to bacterial infections of the bladder.  

Protecting your dog from injury to the best of your ability when he is playing or exercising will help to prevent any complications from trauma and any immune-mediated inflammation which will result from them.

Cost of Getting Swollen Testicles

Treating the causes of swollen testicles will be required to avoid more serious health concerns for your pet.  Here are some of the costs for this treatment:

  • Testicular swelling treatment costs can range from $200 to $1,500
  • Testicular neoplasia treatments costs can run from $400 to $1,200 (for Sertoli cell tumor, Leydig Cell Tumor and Seminoma)
  • Testicular Torsion treatment can cost $500 to $2,000

Swelling of the testicles may be caused by excessive licking of the scrotum leading to swelling, swelling of the testicles themselves (cysts or tumours) or a hernia. I would highly recommend a visit to your Veterinarian to determine the cause and I would also recommend having Breezer neutered at the same time if you are not planning on breeding with him.
