Puppies born with their testicles retained in the abdomen. The normal thing to happen is when they reach four to ten weeks of age, they descend into the scrotum. When they are twelve weeks of age, they should have the situation normalized. If the testicles aren’t in the right place at, the latest, 24 weeks of age, then you should take the dog to the vet to be castrated. Retained testicles can cause serious health problems to the dog, like tumors.
