What are the differences between closed and open castration?
Closed: doesn't penetrate PVT, increases risk of non-secure ligature, decrease risk of scrotal hematoma, decrease post-op swelling and quicker
Open: penetrates PVT, decrease risk of ligature slipping, decrease risk of abdominal hemorrhage, longer
How far should the proximal clamp be placed from the body wall?

Abdominal, inguinal or pre-scrotal
What type of cryptorchidism is more common in dogs?
Unilateral- small dogs prone to this
HERITABLE- DON'T BREED
What are functional characteristics of a cryptorchid testicle?
Sterile because the warm environment destroys sperm
Suppresses spermatogenesis in normal testicle
Predisposed to neoplasia
Predisposed to torsion

Dogs: hip dysplasia, patellar luxation, penile or preputial defects, umbilical hernia
Felines: patellar luxation, short/kinked tail, tarsal deformities, eyelid agenesis
