Need Your Dog's Brace Sooner?







Our braces are made with a Tamarack-Tether hinge, which allows for full range of motion while preventing abnormal motion. The Tamarack-Tether hinge provides smooth articulation and unmatched durability. We offer a lifetime warranty on our Tamarack hinges.


Our braces are made with a Tamarack hinge, which allows for full range of motion while preventing abnormal motion. The Tamarack hinge provides smooth articulation and unmatched durability. We offer a lifetime warranty on our Tamarack hinges.


Our shell is constructed from durable polypropylene. The cast you send us forms the blueprint for the shell, so it is important that you cast your dog's leg correctly. When cast correctly, the resulting custom brace fits the contours of your dog's leg precisely.

Paw segment

Most dog knee and hock braces are made without a paw segment. This is especially advised when the dog is particularly active or has a bilateral (both legs) diagnosis. If you are unsure if a paw piece is needed, please contact your veterinarian before ordering.

A dog knee & hock brace is commonly referred to as a stifle & ankle brace.

Conditions that benefit from a custom knee & hock brace

  • When both the knee and hock joints are affected and/or injured
  • Conditions for which surgery is not available or recommended for your dog
  • Post-operative care following surgery
  • Contralateral (opposite) limb management, preventing your dog from damaging their healthy leg
    • Post-operatively to support the healthy leg
    • Amputation of a hind leg to prevent and/or slow the progression of joint breakdown
  • Reduce sideways motion of the knee (patellar luxation)
  • An alternative to splinting for distal femoral or proximal tibial/fibular fractures
  • Helps prevent hyperextension

Benefits of a Custom Knee & Hock Brace

  • Provides support to the affected area
  • Stabilizes the joint
  • Decreases the time and expense of injury/post-surgical recovery
  • Helps improve your dog's activity level by providing a return to near-normal joint function
  • Allows for easier wound/surgical site inspection
  • Reduces pressure on the contralateral (opposite) limb, preventing further injury

When a Custom dog knee and hock brace may not be suitable

Due to the standard hinge sizes and limited hinge modifications that are currently available, some breeds may have difficulties with the strength of the hinge. Breeds that are less than 15 pounds may have a difficult time bending their knee with the hinges we use, even after modification of the brace and hinge.

Due to the natural anatomy of some breeds, the Custom Dog Knee and Hock Brace may not be able to stay on your dog's leg. Breeds who do not have a prominent hock, such as some Bulldogs, may have difficulties with brace suspension, meaning the brace may slide down the dog's leg with use. The hock is a key point that is used in order to keep your dog's knee brace on their leg.

  • Made in the USA
  • Removable

90 day guarantee on all straps


  • Hand-crafted using vacuum forming and thermal technology
  • Waterproof
  • Tamarack hinges allow motion that mimics normal ligament mobility

NOTE: If this brace is being casted with casting materials not purchased through Animal Ortho Care, ensure the tape being used is soft casting tape. Casts made from hard casting material CANNOT be used to build a brace and will be rejected by AOC Fabrication.

Care & Use


  • Use light soapy water or antibacterial wipes to clean the plastic shell and non-porous liner of the brace.
  • Hand-wash pads as needed and let them air dry.
  • Remove any hair or dirt from the hook and loop straps with a wire brush, gently brushing in one direction on the hook side only.


  • It is required that you follow the break-in period protocol for your dog. This helps to prevent irritation and allows your dog to become comfortable when wearing their brace. Failure to follow the break-in period could result in further injury to your dog. 
  • Your dog may wear their brace whenever they are active, both indoors and outdoors. Custom Dog Knee & Hock braces are waterproof and therefore can be used in the water, such as for hydrotherapy sessions.
  • Remove your dog's brace when they are not active for extended periods of time. This allows their leg to relax, prevents irritation, and allows their skin breathe.
  • Once your dog has successfully completed the break-in period without irritation occurring, they may wear their wrist brace for up to 14 hours a day. Wearing the brace for longer than 14 hours could result in irritation and/or injury.

Break-In Period

Similarly to breaking in a new pair of shoes, the Custom Dog Knee & Hock Brace should initially be worn in short increments as your dog builds up a tolerance to the device. For best results, place the brace on your pet for only half an hour the first day. You can typically increase this time by a further half hour each subsequent day. You can facilitate this process by positively reinforcing and rewarding your dog for wearing the brace. Please keep in mind that the break-in period and time of each increment will depend on your pet's diagnosis and overall acceptance of the brace.

If there is any irritation or skin breakdown, discontinue use of the brace for one full day. If irritation continues, contact us at

Skin & Brace Examination

It is crucial that you thoroughly inspect your pet's skin after each use of the Custom Dog Knee & Hock Brace. This is especially important during the initial break-in period. While it is not uncommon to see minor problems for the first few weeks of brace usage, make note of any blisters or other unusual marks on the skin. Skin redness that does not disappear within an hour after the brace is removed and other signs of skin breakdown are indications of excessive pressure from the brace. The brace can easily be modified to relieve these areas of irritation.

You should also carefully examine the brace itself after each use. Identify any cracks, tears, or areas of unusual wear. Padding and the hook and loop straps can be replaced by contacting Animal Ortho Care. Consult our warranty terms for other details on the service process.

Hygiene & Cleaning

Both the Custom Dog Knee & Hock Brace and areas of skin that come into contact with it must be kept clean. This reduces the chance of your dog contracting contact dermatitis or other skin conditions. Regularly clean the brace with a mixture of half water, half isopropyl alcohol. After cleaning, dry with a towel or let the brace dry at room temperature. Do not speed the drying process through use of applied heat, such as from a hair dryer. Never put a wet brace onto your pet, as it will affect the fit. A properly-fitted brace can be worn in water, but should be thoroughly dried after use before re-application.


  • Outer Shell: polypropylene, polyethylene, co-polymer
  • Inner Liner: closed-cell polyethylene foam




How does this Custom Dog Knee & Hock Brace help my dog?

AOC's Custom Dog Knee & Hock Brace assists with healing from injury and also post-surgery. Additionally, our custom braces help with chronic conditions like arthritis. As a pair, these braces helps with giving added support to your dog's weight bearing leg following the injury of one leg.  

What is included with the purchase of a Custom Dog Knee & Hock Brace?

Purchases of our Custom Dog Knee & Hock Braces include a free casting kit, which you will use before we begin fabricating the brace itself. Once you have cast your dog's leg - or legs if you are ordering a pair of Custom Braces - you will mail us the casts. At that point we craft your brace order based on the cast of your dog's leg, and then send the Custom Braces back to you.

What happens if the brace does not fit correctly?

Please contact us and we will work with you to find the fit! The hook and loop straps give you some freedom to adjust the brace yourself. Depending on the issues with the fit, we may instruct you to ship it back to us for more extensive modification.

Please note it is imperative that you take an accurate cast of your dog's leg in order for the brace to have the best possible fit. Please refer to our casting directions and be sure that you are familiar with them before attempting a casting.

What if my dog's brace needs refurbishment?

Refurbishing your dog's brace is easy. Strap replacements are free within the first 90 days of your purchase if you order and replace them yourself. We offer various methods for refurbishing your brace depending on what needs to be done. You can order new Straps (1 inch or 1.5 inch) and Pads to replace on your own. If you don't want to replace the straps yourself or need a liner replacement, you can use our Custom Brace Refurbish Service and we will refurbish the brace based on what you order.

Is this brace waterproof?

All of our custom dog braces are made with a non-porous padded liner and a polypropylene plastic. Both materials can be wiped down to dry and/or cleaned. Straps and strap pads will need to be air dried.

How often can my dog wear this brace?

There is a two-week break-in period where you will gradually increase the time your dog wears their Custom Dog Wrist Brace by 30 minute increments. Once this period is complete, you may leave the brace on your dog for up to 14 hours a day. However, be sure to remove the brace when your dog is resting, this will prevent irritation and allow their leg to air out. Check for any signs of irritation and/or swelling after removing the brace.

Please remove the brace before your dog goes to bed at night.

Can my dog use stairs while wearing this brace?

Yes! However, give your dog a few days of using the brace before they attempt stairs. If they seem to be adjusting well to the brace and moving comfortably, you should be able to introduce stairs. Be sure to supervise their first few attempts.

How Long is the Fabrication Process?

Once we receive the cast of your dog's leg, it takes 5-7 business days to fabricate the brace. Expedited Fabrication is available for $150.00 per brace which reduces the fabrication time to 3 business days.

How Long Will Shipping Take?

We offer free 5-7 business day ground shipping in the US for both the casting kit and custom brace, as well as 2 Business Day or Overnight shipping options for an additional charge. If you select an expedited shipping option, we will ship the casting kit to you based on that option. Once we receive the cast of your dog's leg and fabricate the Custom Brace, we will ship that using the same option you selected at checkout.

Is the Casting Process Difficult?

The difficulty of casting will depend on your dog; more anxious or badly injured dogs may find the process more distressing. It is recommended that you perform the process with at least 3-4 people depending on your dog's energy level.

Detailed instructions on how to cast are included in the casting kit. We can walk you or your veterinarian through the casting process, so please contact us with questions or concerns before you begin casting your dog's leg. We also offer FREE on-site casting at our Blaine, Minnesota location.

Top Notch Service

When I adopted my Skye, she had been hit by a car and her front leg was broken. Instead of amputating, the foster reached out to get a brace made through Animal Ortho. It was a game changer for my Skye, who has healed and has kept her leg thanks to the wonderful brace made through Animal Ortho. Customer service was wonderful in ordering and additional brace after I got her home. Always get compliments on her brace when we are out and about!!

Hi Kelsey! We are so so happy to hear about Skye's success with her AOC brace! It is always so heartwarming to know our products are making a positive impact in an animals life! We hope she continues to feel better with each day and please reach out to us if you ever have questions, happy to help!
