Anesthetized and prepped

This pup is about to be neutered. Safely under anesthesia, and provided with pre-op pain medicine, he has undergone a sterile prep and is about to enter the surgery room. Note the monitor used to keep up with vital signs even during the prep phase.

Draped and ready

The surgery site is covered by a sterile drape with a small opening over the area to be incised. This protects the sterile surgery site from contamination and subsequent infection.

The incision

A small incision is made in front of the scrotal area and the first testicle is gently pushed towards the incision.

The first testicle

Brief dissection to the first testicle allows the surgeon to quickly expose it and bring it out.


"Control of bleeding". The major vessels to the testicle are identified.

Clamping the vessels

The major vessels are clamped to prevent blood loss when they are cut.

Cutting the vesels

Once the clamps are in place, the vessels and other structures holding the testicle to the body are cut free.


The vessels and associated structures are ligated or sutured to prevent bleeding.

The first testicle is complete

The ligated tissue is allowed to draw back into the incision and disappears.

The second testicle

The same incision is used for removal of the second testicle.

Procedure is repeated

The same procedure is used for the second testicle.

Removal of the second testicle

A small incision is enough to allow the second testicle to come to the surface for removal

Closing the incision

A fine suture material is placed under the skin to draw the edges of the incision closed. By placing the sutures under the skin, this delicate area is less likely to be licked. Also, the sutures do not need to be removed later.

Completed surgery

This puppy has been neutered and can look forward to a life without concerns from many of the medical and behavioral problems that plague intact dogs! It's easy, safe, and quick and will help keep your much-loved dog healthy!




The incision

A small incision is made through the opening of the sterile drape, and the tissues are gently opened to allow entry into the abdomen.

First uterine horn

The uterus is shaped like the letter "Y", with each ovary attached to the top of each branch.

The surgery begins with identifying and withdrawing the first uterine horn through the small incision.

The first ovary

The base of the ovary is ligated to prevent internal bleeding.

Transect the ovarian pedicle

The attachment of the ovary to the body is cut in order to separate and remove the ovary. This is essential to prevent continuing signs of estrus or "being in heat".

Ovary and uterine horn

The first side is completed with the successful separation of the ovary and uterine horn.

Second side

The second ovary and uterine horn is identified, ligated and separated the same way as the first.

The uterine "body"

The last step in a spay is to separate the last attachment of the uterus - the uterine body. The two uterine horns and attached ovaries are now clearly visible. A clamp is being placed across the uterine body.


A suture is being placed around the uterine body to prevent internal bleeding.

Separation of the uterine body

After ligation, the final step is to transect the body of the uterus so the entire uterus and both ovaries can be removed. This prevents signs of heat, pregnancy, and future infections of the former uterus.


The incision in the abdominal wall is closed with small suture.

Skin closure

The skin is being closed with a buried or "subcuticular" suture pattern.

Skin closure

There will be no sutures visible on the surface of the skin.

Surgery completed

This cat has received pain medicine and will wake up comfortably. She can look forward to an easy future with no prolonged heat cycles or litters of kittens!
