Comes in the following sizes: Medium (11-12.5" circumference, 9" tall, 50-75 lbs), Medium Tall (11-12.5" circumference, 11" tall, 50-75 lbs), Large (12.5-14" circumference, 10" tall, 75-100 lbs), XL (14-15.5" circumference, 11" tall, 100+ lbs). To identify the knee (or stifle), it is the joint on the front of the hind leg, just in line with the abdomen. It bends forward when your pup is in a sitting position, so having your pup sit makes it easy to locate. Recommended Use: 1) Place the center vertical crease of the brace itself along the front "edge" of your pup's leg, positioned up as high as possible, with the attached cross-hips strap on the outside of your pup's leg. 2) Wrap the two sides of the brace around towards the back of the leg and fasten the velcro straps snugly. 3) Take the cross-hips strap and put it across your pup's back; fasten the "garter" as high up as possible around the non-injured leg. Shorten or lengthen the cross-hips strap as needed to make it snug. 4) Fasten the clip on the end of the back strap to the clip on your pup's harness. Shorten or lengthen this strap as needed to make it snug. It should pull the cross-hips strap forward a bit, so it doesn't slip down towards your pup's tail. 5) All done! If your pup sits or lies down you will need to adjust these straps again when they get up. Our knee brace design doesn't allow for use on both legs at once.
