How to Measure Your Dog's Leg


Thigh Circumference

Measure the circumference of the thigh, half-way between the Groin and Knee joint line


Tibia Length

Measure the OUTSIDE of the leg, from the head of the fibula (this is the bump just below the knee joint) to above the hock, before the curvature.


Our Dog Knee Braces provide a great solution for stabilizing and supporting your dog's knee following an injury or surgery.

What makes this brace so unique is that it has customizable straps, magnetic fasteners for easy on/off, high quality motion hinges, and cushioning triple layered foam. Your dog will be able to recover confidently with a knee brace that has strong support, yet light on the limbs. 


    • Cranial Cruciate Ligament (CCL) Ligament Tear or Rupture (Most Common use)
    • CCL or Collateral Ligament sprains
    • Post-Surgical and/or post injury recovery
    • Wound management
    • Dog Knee (Stifle) Arthritis
    • Ligaments, tendons, and soft tissue injuries and fractures
    • This brace is NOT recommended for Luxating Patella. Our Custom Dog Knee Brace is most suitable.


    • An orthopedic-style dog knee brace that provides stabilization and protection following CCL surgery
    • Provides active support during rehabilitation following injury or surgery
    • Can be used as an alternative to CCL Surgery, allowing your dog's knee to heal on its own
    • Decrease overall healing time and decreases cost
    • Allows your dog to return to improved activity level and near normal joint function
    • Allows easier wound inspection
    • Can be used to prevent injuries by relieving stress on the weight bearing uninjured leg. Typically after an injury, your dog will place more weight on the sound leg putting it more at risk for injury.


  • The proprietary thermoplastic material can be heated at low temperatures
  • When heated in the Caerus Slim Line Heater, or with a hairdryer, the brace conforms to the shape of your dog's leg.
  • Cushioning medical-grade closed-cell foam eases pressure on affected areas
  • Hook and Loop Closure System featuring Fidlock® Fasteners.
    • Once a snug fit is determined, the Fidlock fastener eliminates the need to readjust for a correct fit every time the brace is applied.
  • Made in the USA
  • Easy to apply and remove
  • 6 Month Warranty


    • Fidlock Fasteners are based on a one-of-a-kind, multi-award-winning technology that revolutionizes traditional fastening systems. The result is a whole new dimension in terms of functionality and safety

    • Range of Motion Hinges
      • Allow a full range of motion, limited range of motion, or a locked position
Fitting Instructions
Use & Care

Use and Care

Wipe down surfaces with isopropyl alcohol.

AOC Ready to Fit and Custom Braces are designed to be worn with a snug fit.  Wearing loosely will result in friction and skin irritation. The following will serve as a reference reminder when you have a general question regarding the wear and care of your pet’s braces.

Feel free to contact Animal Ortho Care with any further questions or concerns for the following braces:

AOC CUSTOM BRACES – 651-447-2411



Break-In Period

Similar to breaking in a new pair of shoes, the Braces must be worn in short, increasing increments in order to build up a tolerance to the device. Both the length of the break-in period and the time of each increment will depend on your pet’s diagnosis and should be discussed with your Animal Ortho Care practitioner and/or veterinarian. For best results, place the brace on your pet for only a HALF Hour the first day and increase by half-hour per day. If there is any irritation or skin break-down, discontinue use for ONE full day. A short period of time is required before your pet accepts the brace. In order to facilitate your pet’s acceptance of the brace, associate with positive reinforcement, such as a treat.

Skin & Brace Examination

It is of extreme importance that your pet’s skin is inspected thoroughly after every usage. This is especially important during the “break-in period.” The occurrence of skin redness does not disappear within 20 minutes or evidence of skin breakdown is a sign of excessive pressure. Any unusual marks on the skin, blisters, or excessive wearing of the device should also be noted. If any of the previously stated conditions present, discontinue the usage and contact Animal Ortho Care. Keep in mind, it is not uncommon to see minor problems within the first few weeks. These braces can easily be modified to relieve any areas of irritation. It is also important to inspect the brace regularly for any cracks or tears. Padding and Hook and Loop (“Velcro”) can be replaced by contacting Animal Ortho Care.

Proper Hygiene

It is important to keep both the skin in contact with the brace as well as the brace itself be kept clean.  This will reduce the chance of your pet contracting contact dermatitis or other skin conditions. Your pet’s brace should be cleaned regularly using a mix of half water-half alcohol and a clean towel. Use a towel or let the brace dry at room temperature. Do not use a hairdryer to speed up the process.  Cotton socks have been provided with Custom Braces only, except for very small braces and stifle (knee) braces, to help with excessive sweating and to keep the device clean. You can wash these with soap and warm water to keep clean. Never put a wet brace or cotton stockinet on your pet. Devices can be worn in the water.  They must be thoroughly dried after use, BEFORE re-applying. 


Complete Application Steps are found with Instructions accompanying each type of Brace.  As a general principle, apply the lower section of Stifle (Knee), Tarsus (Achilles) and Carpal (Wrist) Braces First.  Align the axis point of the hinge or Tamarack with the pivot point of the Knee, Achilles or Wrist Joint, respectively.  For Ready to Fit Braces with Boa Closures, use your Thumb and Index Finger only to snug fit. 

Weekly – Check and Tighten as needed all screws as they may loosen with wear


  • Outer Foam Layer – Loop-backed closed-cell foam
  • Inside Thermoplastic Layer - Low-temperature thermoplastic
  • Inner Foam Layer – Triple Thickness closed-cell foam
  • Range of Motion (ROM) Hinges and Uprights – Lightweight aluminum
  • Fidlock® Fasteners
  • Hook and Loop – Highest grip rating


What conditions can this Performance Dog Knee Brace be used for?

This innovative brace provides prophylactic and rehabilitative support for injuries to the stifle/knee joint and ligament, such as CCL rupture surgical repair. It is indicated for use as an alternative to costly CCL Surgery or when the patient is not a surgical candidate.  The brace may also be used as a sophisticated wound management device with access points post-surgery.  

What is the difference between the Ready to Fit Performance Dog Knee Brace and the Custom Dog Knee Brace?

The Performance brace is a standard size off-the-shelf brace that offers a customizable solution to injury stabilization following injuries and surgery to the knee (stifle) and specifically the Cranial Cruciate Ligament. It has a 6-18 month treatment time. Sizing is based on measurements of your dog, which are listed on the product page. You may need to make adjustments to the brace in order to fit it properly.  

Custom braces are built specifically for an animal. Measurements aren’t needed for this type of brace. Instead, you or your vet would take a cast of the area. The cast is then used to build a custom brace. 

If my dog wears a knee brace will it cause further injury?

Our performance dog knee brace is designed to stabilize and provide support to the Cranial Cruciate Ligament (CCL), further building scar tissue which helps heal the tear.

Why hasn't my vet heard about you? 

Over the last few years, pet parents have had an increasing interest to look for options for their pet outside of the traditional surgery route.  Our orthopedic and custom braces are unique to the market. In addition, our pain management products use the world's first wearable pain relief technology.  Our products can be used in addition to surgery to aid in the healing process.  But we also give customers another alternative when surgery isn't an option.

What is unique about the hinge/hub components?

Our patent-pending design provides Range of Motion (ROM) Control, Axial Rotation of the Extensions and Valgus/Varus deviation. This combination more closely accommodates the range of anatomical variations, making this a truly customizable, off-the-shelf brace. 

Should I leave the brace on my dog all day?

We do NOT recommend your dog wear the brace 24/7. At a minimum, remove the brace during the dog’s longest rest time and at night. Each dog will be different for how much the brace will be needed. 

What if my dog doesn’t like the brace?

Some dogs may need more time to get used to the brace.  For initial product break-in and to prevent irritation, start treatment durations by utilizing brace for 30 minutes on followed by 30 minutes off.  Gradually increase daily.

Great quality but hard to fit

I was really excited about this brave and it was amazing but I couldn’t get it to fit my dog. He’s a 100 lb lab retriever and isn’t your typical size dog. The top strap wouldn’t fit around the top of his leg so there was no way I could make it work. If that part fit, the rest would have been a bit of work but would work. I returned it but I wish the top would have fit because it seemed to be great quality

It is a great concept

Bottom-line; our pooch has a torn ligament. She is a beautiful Lab. We measured, we fitted the brace, & she hated it. Not because it was a thing on her, yet it hurt. We are confident the brace forced the leg to be in a position that she was uncomfortable with. It did aide in keeping her from motion as she did not want to walk with the brace; after PT consult she is innately doing the right thing, as she should not use the leg with the tear, for it could easily cause more damage. She is currently scheduled for surgery and we hope & pray the pins, pain and recovery are successful. I would reconsider, or strongly advise anyone to review the pro’s and con’s of bracing a tear in a hind leg. Please keep my dog in prayer. Her name is, BYA. I love her and will do anything to ease her pain and heal her leg, God Bless

Best customer service EVER!!!

Although I had a difficult time getting this brace onto my dog, Augie, and eventually his limp healed on its own and by giving him Glucosamine chews, I have to say that this company has the most incredible customer service people I've ever dealt with. Victoria was the person I dealt with and she put up with all my questions no matter how silly or how dumb! She was ALWAYS patcent and understanding no matter how often I contacted her or repeated myself. After I recived the brace she was always there to help me along with fittings and adjusting it just right. And trust me, I can be a pain in the you-know-what! But there she was always willing to help! I wish every customer service rep was just like her. And she knew this product forward and backward and trust me, sometimes that was often my problem: "does this part go forward or backward?" ;-) I almost wished it could have worked out for my doggie and me because I wanted so much to make it right if only to make Victoria happy, as well as the entire company. But let me also say, it was one of the VERY BEST products I've ever seen for this sort of injury in a dog. I tried two others and they didn't compare in the quality of this one. So if you're smart, don't bother ordering any other if you really hope to have your dog heal. Just because it didn't work out for Augie, doesn't mean it won't work out for your Pup!!! And, because it didn't work out for me, they were SO kind and fair when it came to returning it!! I got my money back, every penny! I wish them only the best and I wish the same for you and your pup!!! Heal, boy, heal! ;-)


My dog won't wear it
