For many years, spaying and neutering were recommended as a means of preventing many diseases. Do we still give this advice today?
The presence of only one testicle in the scrotum is called cryptorchidism or testicular ectopia. Normally, a dog's testicles descend into the scrotum at two months of age, but in some cases, testicular descent can be a little slower.
Both of these statements are false. The dog does not necessarily have to become pregnant before being spayed.
