How normal is it for a male dog to have three testicles, and should I be worried about this?

While giving my male dog a bath this afternoon, I noticed what seemed like an extra testicle. I've only ever heard of dogs having two, so this is quite unexpected. Is it normal for a male dog to have three testicles, or does this indicate a potential health issue that I should address?

Answer

It's uncommon for a male dog to have more than two testicles. A third mass in the scrotum area can indicate the presence of a health issue, such as a retained testicle or tumor, and should be evaluated by a veterinarian.

  • Most male dogs have two testicles.
  • An extra mass may indicate a medical concern.
  • A veterinary evaluation is recommended for proper diagnosis.

If you've noticed what seems to be an extra testicle in your dog, it might actually be a condition called polyorchidism, which is rare, or it could be something entirely different like a benign or malignant growth, a cyst, or a hernia. It's important to have it checked by a veterinarian to determine the exact cause and appropriate treatment. In some cases, interventions might be necessary to ensure your dog's health and well-being.
