I took Reggie to the vets yesterday to get his first set of shots. The vet now puts his age at about 4 years old. Boy, he aged fast. She said that she can feel only one descended testicle, but that it was a bit hard to examine him due to his sore leg. My question is with a retained testicle, after being neutered, will he act as "stud-ly"? Is there a chance of cancer if it is left? I know that he would not be able to impregnate with it up in his body. I have never had this happen before.
