Size Chart for Medium Breeds
Measure the Rear Leg Height, from the top of the leg where it attaches to the abdomen down to the toe pad, while your pet is lying down, as shown in the photo. Do not pull the leg tight; leave some natural bend.

| Rear Leg Height | Wheel & Strut |
|---|---|
| 10-12" | 6" struts and 8" wheels |
| 13-14" | 9" struts and 8" wheels |
| 15-18" | 12" struts and 8" wheels |
