General Information:
During growth of a male fetus, the testicles develop in the abdominal cavity, pass through an opening in the body wall called the inguinal canal, and descend into the scrotum. Normally both testicles have descended into the scrotum at or shortly after birth. Occasionally descent is not complete until 5-6 months of age.
In some individuals, however, one or both testicles fail to descend into the scrotum. Dogs with both testicles undescended are usually sterile while those with only 1 testicle undescended are fertile. Undescended testicles are most common in small or toy breeds.
Dogs with undescended testicles should be neutered, since the condition is hereditary, the dogs are not eligible for show, and the incidence of testicular tumors in undescended testicles is 14 times greater than in descended testicles.
Treatment Information:
Dogs with the above described condition should be surgically neutered as soon as possible. The procedure involves removing the descended testicle (if present) in the normal manner. The other testicle is removed through an incision located in the inguinal area (between the inside of the leg and the abdomen) or located along the mid-line of the abdomen just in front of the prepuce.
