Retained Testicles Can Be Dangerous for Dogs
Cryptorchidism (undescended testicles) can cause serious health and behavior problems if not detected and treated.
How does it happen that testicular descent fails to occur in some cases? As the canine fetus develops, the testicles are formed in the abdomen, near the kidneys. Usually, as the puppy grows – initially, in utero, and then, after his birth – his testicles are gradually pulled from the abdomen, through the inguinal canal (a passageway through the abdominal wall), and into the scrotum by the gubernaculum, a ligamentous cord connecting the testes to the scrotum.
