Shoulder Injuries in Dogs: Signs, Treatment and Recovery

By Dr Duncan Houston

A dog who limps after a run may have a shoulder problem, but watching the gait alone cannot locate the injury. Pain in the paw, elbow or neck can produce a similar front-leg limp.

The important first decisions are how painful the dog is, whether they can bear weight and whether trauma occurred.

Quick Answer

Shoulder problems can cause front-leg lameness, stiffness and reluctance to run or jump. Causes include tendon injury, joint instability, developmental cartilage disease and trauma. Stop strenuous activity and arrange a veterinary examination; sudden inability to bear weight, obvious deformity or severe pain needs urgent assessment.

What can go wrong in the shoulder?

• Soft-tissue injury: muscles, tendons or supporting ligaments can become strained or damaged.
• Biceps or supraspinatus tendinopathy: tendon disease may cause persistent or recurring lameness, particularly with exercise.
• Osteochondrosis and OCD: abnormal cartilage development can produce a painful flap within the joint.
• Instability or luxation: the joint may move abnormally or become dislocated after trauma or because of underlying structural problems.
• Arthritis: previous joint damage can lead to ongoing pain and reduced movement.

The American College of Veterinary Surgeons describes shoulder OCD particularly in growing large and giant-breed dogs. It can affect both shoulders even when only one leg appears lame. A specialist review also covers tendon disorders, instability and other shoulder abnormalities.

How urgent is the limp?

What else will the vet rule out?

A torn nail, foreign material between toes, elbow dysplasia, fracture, neck disease, infection or bone cancer may cause forelimb lameness. Age, onset, fever, swelling and the examination guide which possibilities matter most.

The vet observes movement and examines the whole limb and neck. X-rays assess bones and joints, but a normal X-ray does not exclude tendon disease. Ultrasound, CT, MRI or arthroscopy may be recommended for selected cases.

When is this an emergency?

Seek emergency care after significant trauma, for an obviously displaced limb, uncontrollable pain, collapse or breathing difficulty. Keep the dog quiet for transport. Do not attempt to put a shoulder back into position or pull the leg to assess its movement.

What should you do while waiting?

1. Use short lead-controlled toilet trips and prevent running, jumping and rough play.
2. Provide non-slip footing and block stairs where possible.
3. Film a few natural steps only if doing so does not cause extra pain.
4. Use only medication prescribed for this dog. Human painkillers can be dangerous.
5. Record whether the problem began suddenly, follows exercise or is worst after rest.

Treatment and realistic recovery

Treatment follows the diagnosis. Some soft-tissue injuries need controlled rest and a tailored rehabilitation programme. Certain cartilage lesions, dislocations or severe instability may require surgery. Arthritis management usually combines weight control, appropriate activity and pain management.

Recovery may take weeks to months, depending on the damaged structure. Comfortable walking does not automatically mean a tendon is ready for sport. Rechecks and a staged return to activity are safer than a fixed internet timetable.

Common mistakes and prevention

• Calling every limp a sprain without examination.
• Massaging or stretching a painful joint before diagnosis.
• Restarting ball chasing as soon as medication masks the limp.
• Adding supplements instead of correcting weight or exercise load.

Build fitness gradually, avoid repetitive high-impact activity in unconditioned dogs and feed growing large-breed puppies an appropriate complete diet without unprescribed mineral supplements.

Frequently Asked Questions

Can shoulder pain disappear with rest?

Signs may improve, but recurrence suggests the underlying problem needs investigation.

Will every shoulder injury need surgery?

No. The diagnosis and severity determine the best approach.

Can my dog swim during recovery?

Only if the treating vet or rehabilitation professional recommends it. Swimming still loads the shoulders.

Accurate localisation is the foundation of recovery. Protect the limb first, then build the treatment plan around a diagnosis.
