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 – 703-474-6204



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, start treatment durations by utilizing the brace for 30 minutes ON, followed by 30 minutes OFF, gradually increasing daily. 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 the 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 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 the 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.

Incredible Device!

Our 7 year old Chessie was recently diagnosed with an ACL injury. He did not have a complete tear but was well on the way to major damage. We took him to two different vets and the estimates that came back ranged from $3,000 to $4,500 for a surgical repair. I began looking for alternative options and discovered the Performance Knee brace from Animal Ortho. The idea that this would still allow movement while letting the injury heal and scar tissue to form coupled with several thousands of dollars in savings and no recovery period made the choice simple.

We received the brace and followed the instructions for fitting and adjusting. We then gradually worked it from 15 minutes a day up to a full day over the course of a month and removed it only at night. By 8 weeks we reduced the wear time to occasional usage.

We also keep his weight down and activity level to a walk or only occasional run to avoid reinjuring. He is now using the leg like normal with a slight limp but he appears to have little or no pain!

What a great device! Thank you and keep up the great work!

Great Alternative to Surgery

After my vet told me there were 2 surgical options for ACL/CCL tears, both of which wouldn't fix the actual injury, but were priced at $1800 and $3500 each, I asked about braces. He said he didn't recommend any braces. Even when I asked about the potential positives about getting a brace, he refused to mention any. I could tell there was some bias there because surgical options would make him a bunch of money, so the obvious choice was to buy a brace as a first attempt before the surgical option. I purchased this one because it seemed like a good choice. These are my thoughts on the brace:
- It definitely helped my dog. It took a few minutes for her to get used to it, since she'd been limping for 2 weeks before I got the brace. Within the hour, she put full weight on it and was walking well.
- Whenever she runs, she still chooses to run on 3 legs. I assume this is due to the motion restriction of he brace. Maybe I just need to adjust it to extend range of motion.
- After a few weeks of using the brace, I was able to take it off and she is able to walk much more with weight on her injured leg. I assume this is due to some scar tissue build up and healing of the muscles around the injury, which weren't able to heal before the brace was applied.
- Summary: This brace works!!!

- I screwed up the initial cut of the foam padding because I was trying to avoid tucking it under the opposite side. Current design requires you to be very specific to protect your dog's leg from pinching. Take your time, especially for the upper strap. I recommend a design change, so that there are 2 foam strips, spaced to allow the adjustable strip to fit in the middle, on the opposite side of the adjustable foam strip. This would basically make it significantly easier to size the adjustable side, because there would be much better tolerance for cutting.
- It tended to slip down her leg. I found that the best way to prevent this was to fit the lower side to rest on ...

Knee brace

We could not get the brace to fit our dog but customer service was very nice about the whole experience

Kaydee's knee

This is my 4th rottweiler and the first with a severe knee injury. Our vet prescribed pain medication along with rest and to avoid further inflammation. Our other options are $ 4000.00 surgery which is not realistic overall. So for 8 weeks we have worn the brace and slowly have improved the stability of her knee. We are hoping that this will provide the right amount of support until she's heeled enough to avoid having to look at surgery. Will let you know how we do, what an amazing opportunity to avoid having an operation. Would be nice to teach more vets about these wonderful devices vers sending you to the operating room.

Paiely's Brace

Unfortunately, we did not get to use the brace. She passed away from another medical condition.
