Size guide

Getting the fit right

Sized on the distance across the hock joint, from the point above it to the point below it.

Not sure which size? 2 quick questions and we'll tell you which size — and why.

How to measure

  1. Distance across the hock (A–B)With your dog standing, measure down the leg from just above the hock to just below it.
  2. Body weightWeigh your dog as a cross-check.

Size chart

SizeDistance A–BWeight
X-Small / Small 8.0 – 10.2 cm 10.0 – 15.0 cm
Medium / Large 10.2 – 14.0 cm 15.0 – 44.9 cm
X-Large / XX-Large 14.0 – 17.8 cm 44.9 – 90.0 cm
Only three sizes, each covering a wide span — so the distance measurement matters more here than on a six-size brace. Measure twice.

Why it works

What makes this different

01

You set the range of motion

A locking external hinge holds the hock anywhere from fully immobilised to a controlled arc. Full lock is 30° flexion / 45° extension; reduced range for rehab is 30° / 15°.

02

Built for the post-op window

Lock the joint out while things knit, then open the range gradually as your vet or physio directs. Controlled movement is what keeps strain off a healing tendon.

03

Adjustable in both directions

Breadth and length both adjust — the upper and lower cushioning lengthens or shortens, so one size covers a genuine range of leg shapes.

04

Non-neoprene throughout

Neoprene traps bacteria, gives less support and degrades. Balto use a ventilated non-neoprene fabric that breathes and keeps its shape wash after wash.

The details

Everything you need to know

From what's inside to how it arrives — open any section below for the full picture on Balto® Flexor - Adjustable Hock Brace.

A hinged hock brace that lets you set how far the joint bends — from fully locked after surgery to a controlled arc through rehab.

Set the hinge before fitting. Balto give two reference settings: 30° flexion / 45° extension for full immobilisation, and 30° flexion / 15° extension for reduced range of motion during rehabilitation. Your vet or physiotherapist decides which and when.

  • With your dog standing, position the brace so the hinge sits level with the hock joint.
  • Fasten the upper cushioning first, then the lower.
  • Snug, not tight. You should get two fingers under any strap.
  • Adjust the upper and lower cushioning length so the brace spans the joint without pressing into the paw or the knee.
  • Watch the first few minutes of walking. The hinge should track with the joint, not sit forward or behind it.

A brace supports a joint. It doesn't fix what's causing the problem, so keep your vet in the loop — particularly if your dog is in pain, the limb is swollen, or things are getting worse rather than better.

  • Build up wearing time gradually. Start with short sessions and check the skin underneath every time you take it off.
  • Stop and reassess if you find rubbing, hair loss, swelling or broken skin.
  • Take the brace off overnight unless your vet has told you otherwise.
  • Never leave a braced dog unsupervised on a lead or in a crate.
  • For dogs under two years old, use in balanced intervals so growth isn't affected.

Hand wash in cool water with mild soap and air dry away from direct heat. Don't tumble dry, and don't put it on a radiator — heat distorts the shaping and the velcro.

Common questions

Frequently asked questions

Both support the tarsus. The Hock stabilises and compresses, and its splints come out — good for ongoing support, arthritis and protecting a dressing, and it's a third of the price. The Flexor controls how far the joint bends, which is what a post-surgical protocol needs. If your vet has given you degrees to work to, get the Flexor.

Ask your vet or physiotherapist. It depends on what was done to the joint and how far into recovery your dog is, and getting it wrong in either direction sets things back. Balto supply two reference settings and the means to switch between them, but the decision isn't one to make from a product page.

Because the length and width both adjust, each size covers a span that would take two sizes on a fixed brace — hence the paired names. It does mean the distance measurement matters more than usual, so measure across the joint carefully rather than going by weight alone.

Yes — Balto list contralateral support as an application. When one hock is out of action the other takes the load, and dogs frequently injure the good leg as a result. Worth discussing with your vet if your dog is compensating heavily.
