Cryptorchidism: Undescended Testicle(s)
Cryptorchidism is found in almost 10% of male dogs. Cryptorchism is the absence of one or both of the testes in the scrotum, and the condition is considered to be a birth defect.
When a male puppy is born, his testicles are still located within his abdomen. This is true for all dogs--not just Weimaraners. As the male puppy grows older, his testicles slowly descend into the scrotum. Generally, both testes drop into the scrotum by about 6 weeks of age. Some puppies do develop a little slower than others, but if one or both testes are not present in the scrotum by about 12 weeks of age, the puppy is probably cryptorchid. The testicle that has not descended is either within the abdomen or it may be located in the inguinal (groin) tissues.

If only one testicle has descended the dog is probably able to breed. But because it's an inherited condition, breeding is not recommended. And, if you are considering a Weim puppy, make sure there is no history of undescended testicles in his hereditary background. Treatment is surgery. Additionally, castration is advised on dogs with an undescended testicle due to the high rate of testicular cancer in dogs with cryptorchidism. Removal of an undescended testicle can be more complicated than a typical neutering procedure. When your puppy returns home try to limit his activity so he can heal quickly. Don’t let him lick or chew at his wound.
