The Balto® Flexor Dog Hock Brace is a veterinarian-approved solution designed for dogs recovering from serious hock injuries or post-surgical rehabilitation. Built with an adjustable hinge system, the Flexor allows you and your veterinarian to customize how much your dog’s hock can move during healing. The joint can be completely immobilized after surgery or set to allow controlled flexion and extension as your dog regains strength; helping ensure proper healing while reducing strain and stress on the injured joint.
Made from breathable, non-neoprene material, the Balto® Flexor is comfortable for long-term wear, washable for easy care, and trusted by veterinarians for its advanced design. Two lightweight aluminum splints stabilize the hock, while adjustable straps and padding provide a secure, custom fit. This brace is an excellent choice for dogs who need more than basic support during recovery, especially in severe injuries or rehabilitation plans.
- Why pet parents choose the Balto® Flexor:
- Advanced post-surgical support: Provides stabilization after procedures involving the hock joint.
- Customizable healing: Adjustable hinge locks allow full immobilization or controlled range of motion during rehab.
- Pain and instability relief: Helps manage acute hock pain or congenital joint instability.
- Secure, tailored fit: Length- and width-adjustable padding ensures comfort and stability for a wide range of dogs.
The Balto® Flexor can also be used as a conservative alternative for dogs who are not candidates for surgery, or to provide extra support for the opposite limb when one leg is recovering. Available in sizes X-Small/Small through X-Large/XX-Large, the brace is designed to fit securely for breeds of many shapes and sizes. (Note: For dogs over 50 kg / 110 lbs., the brace should not be extended more than 1 cm on either end to maintain proper alignment.)
With the Balto® Flexor, your dog receives the highest level of hock protection and recovery support, helping them heal safely and return to a more active, comfortable life.

Step 1
Adjusting the upper and lower padding (if needed): Use the biggest tool to loosen the two screws. Adjust the height of the padding by sliding it on the guide rail and then tightening the screws . Repeat on all four (Fig. 1 & 2).Step 2
Adjusting the hinges: Use the smaller tool to adjust the hinges (Fig. 3).Step 3
After setting the length and degree, prepare the brace by opening the straps. Place the brace on the leg and position the brace by lining up the central hinge with the tarsus (hock) (Fig. 4).Step 4
Secure all the Velcro straps (starting with the bottom strap) around the leg by passing them through the buckles. Tightly close with the Velcro straps (Fig. 5 & 6).- To which degree setting should my brace be set to?
- For full immobilization of the joint, we recommend setting at the 30° flexion and the 45° extension. For a reduced range of movement for the joint, we recommend setting at the 30° flexion and the 15° extension. For other degrees, or more custom settings we recommend working with your veterinarian. Watch our video on how to adjust the degrees.
- How tight do screws need to be?
- Until you meet resistance then stop, don't keep going. Continuing to tighten after feeling resistance can cause the metal to wear excessively over time; leading the brace to not work as intended.
- Which is better, the Hock brace or the Flexor brace?
- Choosing between the options all depends on your doggo’s needs. The Flexor brace is typically used post-surgery or for more advanced injuries because it allows you to slowly reintroduce mobility as they heal. You can adjust the settings as needed. The Hock brace provides compressive and structural support.
