A. I don't believe your vet meant actual castration but possibly a prescrotal urethrostomy. This surgery redirects your dog's urethra away from the penis to a surgically created opening in front of the scrotum. It is performed in cats and dogs to treat and/or prevent urinary obstruction from stone formation. Cystine crystals have the potential to become cystine stones which can cause a urinary obstruction.
