There are 4 vests  in the colors and numbers shown unless you ask for additional custom designs. They are custom designed to fit a specific dog. You will need to supply accurate measuremets to allow custom manufacturing of these numbered vests. Measure your dog: 1) neck circunmference at the lowest point near the shoulders and chest 2) Length of back from collar at shoulders to the narrowest point of the waist along the back 3) Measure the distance from the dogs elbow (Back of the elbow) to the narrowest point of the waist (or to privates on males) on the belly side 4) Measure the chest circumference near the shoulders and just behind the elbows 5) Measure the distaance from the bottom of the collar on the chest to the back of the elbows (at the place where you measured the chest) just behind the elbows; this measurement is for the chest plate of the vest. See the measuring diagram in the ABOUT SECTION PAGE. If you need further help please email or call  for help measuring accurately.
