Canine Osteosarcoma – All You Need to Know
Is Your Dog Affected by Osteosarcoma?
Osteosarcoma in dogs is challenging. Fill in the form below and describe your pet’s case, including the vet’s diagnosis. Please upload any photos, diagnostic images, or videos of the affected limb(s) — we’ll assess if your pet may benefit from a custom-fit WIMBA brace.
Understanding Canine Osteosarcoma
Caring for a dog diagnosed with osteosarcoma can feel overwhelming, but there are ways to support their comfort and mobility throughout their journey. Understanding how to help your dog maintain balance and ease of movement, even during treatment and recovery, is key to preserving their quality of life. In this article, we explore how supportive tools like orthoses can play an important role.

What Is Osteosarcoma in Dogs?
Osteosarcoma is the most common type of bone cancer in dogs. It typically affects the long bones of the limbs, such as the radius, humerus, femur, or tibia, and occurs most frequently in large and giant breeds.
The disease is aggressive in nature, with cancer cells that destroy healthy bone tissue and often spread to other parts of the body, particularly the lungs.

Common Signs and Symptoms of Canine Osteosarcoma
Signs of osteosarcoma can include lameness, swelling over a limb, or sudden pain without a visible injury.
How Is Osteosarcoma Diagnosed in Dogs?
Diagnosis is usually made through radiographs (X-rays), sometimes followed by advanced imaging or biopsy. Because the affected bone becomes weak and prone to fracture, early treatment is essential for pain relief and quality of life.
Treatment Options for Dogs with Osteosarcoma
Whether your dog is undergoing surgery, receiving palliative care, or adjusting after limb amputation, you may be wondering how supportive tools like orthoses or mobility devices fit into their care.
The short answer is that they can help, but it is important to understand the whole picture and always seek the guidance of your rehabilitation, surgical specialist, oncologist, and/or primary care veterinarian.
Why Orthoses Aren’t Applied to the Affected Limb
`When a limb is affected by osteosarcoma, applying direct external pressure, such as from an orthosis, is not recommended. The cancer weakens the bone and increases the risk of fracture, even during normal movement. Adding the pressure or constraint of a brace can raise that risk further.
Radiation therapy can also be a blessing but complicates Veterinary Orthotic and Prosthetic use. While sometimes used to slow cancer progression, radiation impacts soft tissue healing and skin integrity. This makes the area more prone to irritation, delayed healing, or pressure sores, and typically rules out the use of prosthetics or external support on the affected leg.
For these reasons, custom orthoses are not used directly on the limb with active osteosarcoma or undergoing radiation treatment.For these reasons, custom orthoses are not used directly on the limb with active osteosarcoma or undergoing radiation treatment.
Where Orthoses Can Help
While we do not brace the affected limb, we can support the rest of the body — especially when a dog is recovering from amputation or shifting weight away from a painful leg.
In these cases, the remaining limbs often work harder to keep your dog mobile. This shift can lead to joint strain, fatigue, or long-term issues like soft tissue injury or osteoarthritis in the remaining limbs. That’s where lightweight, custom orthoses can provide valuable support.
Your pet’s comfort matters.

How the WIMBA Go Supports the Body
The WIMBA Go is a custom-fitted orthosis designed for proactive support of distal joints, such as the carpus (wrist) or tarsus (ankle). It is used on limbs showing early signs of overuse or instability to help prevent further damage or fatigue.
WIMBA Go orthoses are:
Custom 3D Printed
Custom made with advanced materials and 3D printing technology.
Lightweight
Designed to be as light as possible, allowing for natural and comfortable movement throughout the day.
Supporting Joints
Designed to support joints and reduce compensatory strain.
Easy to Integrate
Easy to integrate into long-term comfort and mobility plans.
When used alongside rehabilitation, WIMBA Go orthoses help preserve whole-body function and support a more balanced gait during recovery or long-term care.
Additional Ways to Support Comfort and Mobility
Orthoses are just one part of a broader plan. Many dogs benefit from a combination of home modifications, mobility tools, and hands-on rehabilitation care.
Some practical options include:
Supportive harnesses that allow safe lifting during transitions, stairs, or uneven terrain
Non-slip flooring, such as yoga mats or carpet runners, to reduce fall risk in the home
Nail grips or traction socks for dogs who have difficulty with smooth floors

Wheeled carts, which may be recommended in specific cases by a rehabilitation professional, especially when hindlimb strength or balance is compromised, and should be prescribed and fitted by a veterinary professional to avoid potential harm.
Targeted rehabilitation exercises that maintain strength, flexibility, and coordination.
Pain management and nutritional support, guided by your veterinarian.
These tools work together to reduce stress on the body, maintain independence, and protect quality of life.
Final Thoughts
Osteosarcoma is a difficult diagnosis, but it doesn’t have to mean the end of comfort or mobility. While orthoses are not used on limbs affected by cancer or radiation, they can still play an important role in maintaining balance and reducing the physical cost of compensation.
With thoughtful planning and collaborative care, we can protect your dog’s comfort and dignity every step of the way.

PET STORIES
WIMBA Orthosis in Action:
Cruciate Ligament Rupture
Jack
Diagnosed with immune-mediated thrombocytopenia (ITP), an autoimmune disease, surgery was simply too risky for Jack. So when he ruptured his CCL, conservative management became the only option. With the support of his dedicated vet and rehabilitation team – and a custom WIMBA Stifle Brace – Jack has regained stability, confidence, and improved weight-bearing throughout his recovery.
“Since fitting Jack has increased his walks, he has improved weight bearing and in time will gain more hamstring muscle mass. We’ve got a journey to go yet but safe to say Jack is ending the year on a positive note.”
