Size guide
Fit depends on the shape of the lower back leg, not on weight or breed. It takes about three minutes and one helper with treats.
Three measurements
You need a soft tape measure. No tape? Use a piece of string, mark it, and measure the string against a ruler.
Stand your dog square
Flat floor, weight on all four legs. Measuring a dog that is lying down or sitting gives a smaller number.
A · Above the hock
Around the leg, about 3 to 4 inches above the hock joint. Snug against the fur, without squeezing.
B · Below the hock
Around the leg, about 3 to 4 inches below the hock joint.
C · Height
The vertical distance between A and B. The brace height for your size needs to fit within the lower leg.
Measure both back legs
They can differ. Use the larger numbers.
Size chart
| Size | On Amazon | A · Upper width | B · Lower width | C · Brace height |
|---|---|---|---|---|
| S/M | Intermediate (S/M) | 5.9 in · 15 cm | 4.5 in · 11.5 cm | 6 in · 15.2 cm |
| M | Medium | 6.1 in · 15.5 cm | 4.7 in · 12 cm | 7 in · 17.8 cm |
| L | Large | 7.1 in · 18 cm | 5.3 in · 13.5 cm | 8.1 in · 20.5 cm |
| XL | X-Large | 7.9 in · 20 cm | 6.1 in · 15.5 cm | 9.1 in · 23 cm |
These are the dimensions of the brace laid flat, not leg-circumference ranges. The straps and extension straps adjust around the leg. Measure your dog first, and do not choose by breed or weight alone.
Please measure before ordering.
- Very small dogs may not fit. Toy breeds and dogs with very short or very thin rear legs may be too small for this brace.
- If your dog’s rear leg height is under 6 in (15.2 cm), the brace may not fit.
- Giant dogs may not fit. Very large breeds can have back legs that are too tall or too thick.
Common measuring mistakes
Choosing by weight
A lean 60 lb dog and a stocky 60 lb dog can need different sizes. Go by the tape.
Measuring the knee
The hock is the lower joint that points backward. The knee is higher, near the body.
Pulling the tape tight
Compressing the fur gives a number that is too small. Snug is enough.
Measuring while lying down
The leg changes shape under load. Always measure standing.
Between sizes?
Tell us A, B and C. The extension straps add reach, and we will help you decide.
Thick coat?
Measure over the coat as it normally lies. The straps take up the difference.
How a good fit looks
- The brace sits over the hock and does not slide toward the paw after a short walk.
- A finger slides under each strap.
- Your dog puts weight on the leg as usual.
- No swelling, cold toes, or rubbed skin after wearing.
