Here's why:
* Neutering: Neutering involves surgically removing both testicles. This procedure permanently prevents the dog from producing sperm and eliminates the hormones responsible for testicular growth.
* Cryptorchidism: Some male dogs are born with one or both testicles undescended (cryptorchidism). In such cases, a veterinarian may recommend surgery to remove the undescended testicle(s).
* Misunderstanding: It's possible that you may be observing something else, such as a swollen lymph node or a skin growth, that resembles a testicle.
If you're concerned about your neutered dog, it's best to consult with your veterinarian. They can examine your dog and determine the cause of any unusual swelling or growth.
