The area that will be operated on must be shaved to remove hair.

Here a doctor is using an electric shaver to prepare the area

After shaving, the area is completely covered in an anti-bacterial solution to kill germs that normally live on the skin.

Here the doctor is applying the solution.

After shaving and applying the solution, sterile sheets are placed over the horse (all except the head).

A small area is cut into the sheet and the operation is performed in this area.

Here we see Dr. Anne Baskett performing surgery on the horse.

Notice that everyone is wearing scrubs, gowns, masks, caps, and gloves.
