Osteoarthritis (Degenerative Joint Disease) in Dogs
This page is for educational purposes only and is not a substitute for veterinary diagnosis or emergency care. Always consult your primary veterinarian or a rehabilitation veterinarian before starting treatment. If your pet cannot walk, has sudden paralysis, severe pain, or breathing difficulty, seek urgent veterinary attention.
What is Osteoarthritis (Degenerative Joint Disease) in Dogs?
Also known as: degenerative joint disease (DJD); canine osteoarthritis (OA); arthritis in dogs.
Osteoarthritis (OA), also called degenerative joint disease, is the progressive deterioration of articular cartilage with secondary changes in bone, synovium, and periarticular soft tissues. As cartilage thins, joint surfaces load unevenly, inflammation rises, and pain behaviours appear — often long before owners realise the pet is sore.
OA can affect hips, elbows, stifles (knees), shoulders, carpi, tarsi, and the spine. It is frequently secondary to developmental joint disease (for example hip or elbow dysplasia), cruciate ligament injury, osteochondrosis, or prior trauma, and it becomes more common with age. Large and giant breeds are predisposed, but small dogs develop OA too — especially after jumps, falls, or conformational stress.
There is no cure that restores original cartilage. The clinical goal is lifelong multimodal management: control pain, maintain muscle, preserve range of motion, keep body weight in a healthy range, and adapt the home and exercise plan so the dog stays as comfortable and functional as possible.
Common signs to watch for
Signs vary by severity and by whether your pet is a dog or cat. Owners of dogs often notice:
- Stiffness after rest that improves slightly with gentle movement (“warm-up” effect)
- Limping or shifting weight off a painful limb
- Reluctance to jump into the car, onto furniture, or climb stairs
- Shortened stride, bunny-hopping, or a crouched gait
- Difficulty rising from lying or sitting
- Licking or chewing over a joint
- Reduced play, shorter walks, or irritability when touched near joints
- Visible muscle loss (especially over hips or thighs) from disuse
Causes & contributing factors
- Age-related cartilage wear and reduced joint homeostasis
- Developmental orthopaedic disease (hip dysplasia, elbow dysplasia, OCD)
- Prior joint trauma, instability, or surgery (including cruciate disease)
- Obesity increasing joint load and inflammatory signalling
- Repetitive high-impact activity on vulnerable joints
- Genetic predisposition in many large and giant breeds
How veterinary rehabilitation helps
A rehabilitation veterinarian assesses gait, joint range, muscle mass, pain behaviours, and functional tasks (sit-to-stand, stairs, getting into cars). Findings guide an individualised multimodal plan coordinated with your primary vet’s medical care.
Land-based physiotherapy and controlled therapeutic exercise aim to improve joint nutrition through motion, rebuild supporting muscle, and retrain efficient movement patterns without flare-ups.
Hydrotherapy (when appropriate) allows strengthening with reduced weight-bearing. Manual therapy, acupuncture, and other modalities may be layered to address pain and stiffness. Home exercise programmes and environmental modifications extend progress between clinic visits.
Rehabilitation plans at RehabVet are individualised after a veterinary assessment. We coordinate with your primary vet when imaging, medication, or surgery is part of the overall plan.
Modalities & services commonly used at RehabVet
Depending on your pet’s examination findings, comfort, and goals, a plan may include one or more of the following:
Expected rehabilitation goals
Goals are set for the individual patient. Typical aims may include (not guarantees — outcomes vary):
- Reduce pain behaviours and improve comfort during daily activities
- Maintain or improve joint range of motion within safe limits
- Rebuild and preserve muscle mass that supports affected joints
- Improve gait quality and confidence with stairs, rising, and walks
- Support healthy body condition to reduce joint load
- Equip owners with a sustainable home exercise and activity plan
We do not publish invented success percentages. Progress is tracked clinically (gait, strength, range of motion, pain behaviours, and home function) and plans are adjusted over time.
When to seek veterinary care
- Persistent limping, stiffness, or reluctance to exercise lasting more than a few days
- Sudden non-weight-bearing lameness (rule out acute injury first with your vet)
- Rapid muscle loss, collapsing on walks, or inability to rise
- Pain that is poorly controlled despite current medication
- Before starting an intensive exercise or hydrotherapy programme — assessment first
“Arthritis” means joint inflammation. Osteoarthritis is the most common chronic form in dogs — cartilage degeneration with secondary inflammation and bony change. Other types (for example immune-mediated polyarthritis) behave differently and need different medical work-ups.
Rehab cannot regenerate lost cartilage or erase radiographic OA. It can meaningfully improve comfort, strength, and function, slow secondary decline from disuse, and help many dogs stay active for longer when combined with weight control and veterinary pain management.
OA is a lifelong condition. Many dogs benefit from an intensive phase followed by maintenance sessions and a home programme. Frequency depends on severity, flare pattern, and how well the home plan is followed.
When screened and supervised, aquatic therapy is often useful because buoyancy reduces joint load while allowing muscle work. Not every dog is a candidate (skin disease, uncontrolled cardiac/respiratory disease, extreme fear of water, and some neurological statuses may preclude it). Assessment decides suitability.
