Vasectomy is a relatively new procedure in the canine world and we are still learning as the differences between humans and dogs.

When considering this procedure for your dog, it is important that we take the opportunity to review some basic information beforehand in addition to doing a full examination of the potential surgery.

An estimated cost will be provided upon the presurgical consult that will be based on age and weight. Please note that a vasectomy does cost a little more than a standard castration.

Important facts to know about the canine vasectomy operation:

1. Vasectomy involves cutting and tying off the vas deferens tube which
leads from the testes out to the end of the penis. It is located on both
sides and thus two incisions are needed. The vas deferens in the dog are
deeper than humans and buried in fat so it takes some time to locate the
tiny tube in surgery.

2. After the presurgical preparations, the patient is placed in the
surgery suite under gas anesthesia. The surgeon then applies a local
anesthetic to the area. Once the vas deferens is located and isolated and
brought outside the body area, the surgeon does a double ligature ("tie
suture") on each end of the tube and then cauterizes the ends to prevent

3. Everything is returned to the body and sutures are applied under the
skin as well as in the skin itself. A pain injection is administered that
typically lasts 24 hours.

4. Bruising is a common occurrence due to the gentle nature of the
delicate skin in that area but is typically minimal. After the procedure,
which typically takes 30-60 minutes, the patient wakes in recovery and gets
fitted with a cone to prevent licking at the surgical site. They go home
with the intent that the cone stays on for 24/7 for one week and a few more
days of gentle pain control is sent home.

Vasectomy vs Neuter:

We know from the human world that one testicle is plenty to impregnate a female so we don't remove just one testicle.
So the choices for a male are either remove both testicles as a castration (neuter) or consider a vasectomy. The important distinction between castration and vasectomy, of course, is the retained hormones.
