Do dogs and cats with shoulder joint or tendon injuries need X-rays?

X-rays are usually recommended first to rule out fractures or joint dislocation. If soft tissue injury is suspected or a more detailed assessment is needed, the vet may recommend advanced imaging such as CT or MRI.

Can ligament or tendon injuries heal with rest alone?

Mild strains or inflammation may initially be managed with rest and restricted activity, but if lameness or pain persists a vet assessment is needed to determine whether further treatment or surgery is required.

How long does post-operative rehabilitation typically take?

Recovery time varies with the severity of injury and type of surgery. Mild cases may take a few weeks to a month, while more serious cases can require several months. Always follow the guidance of your vet and rehabilitation therapist.

What can I observe at home to help the vet assess my pet?

Record gait videos (front and side view), note when the symptoms started and any changes in appetite, and share all of this with the vet at the appointment.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek immediate veterinary care (emergency)

•Sudden inability to use the limb or obvious loss of strength
•Penetrating wound or exposed bone at the injured site
•Rapid swelling at the affected area accompanied by a significant drop in appetite

Schedule a clinic visit soon (within 24–72 hours)

•Noticeable limping but still able to walk briefly
•Flinching or showing pain when the shoulder is touched
•Decreased activity and reluctance to jump or climb stairs

01What symptoms indicate a problem?

Shoulder joint and surrounding ligament or tendon issues typically present as changes in movement and tenderness, and may affect one or both limbs.

Limping on one or both limbs, lifting the leg or refusing to bear weight while walking
Reluctance to jump, go up or down stairs, or engage in active play
Flinching, crying out, or showing obvious discomfort when the shoulder is touched
Overall decrease in activity level, less spontaneous movement or play
Swelling, warmth, or tenderness felt at the affected area

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden inability to use the limb or obvious weakness
⚠️ Penetrating wound or exposed bone at the injury site
⚠️ Rapid swelling at the affected site accompanied by significant loss of appetite

02How to assess the problem at home: key observations and emergency criteria

Home records help your vet make an initial assessment — video footage and timestamps are especially valuable.

Record front-view and side-view gait videos on your phone for comparison
Note the date and time the limping or pain was first observed
Monitor for changes in appetite, water intake, and overall alertness
Measure or describe any recent weight changes and record urination and defecation patterns
Note any obvious avoidance or pain response when touching the affected area
Video and written records can be shared with a specialist clinic for preliminary assessment

03How will the vet diagnose the problem? Common diagnostic tests

After arrival, the vet will start with a physical examination and imaging assessment, arranging advanced tests as needed to confirm the extent of injury.

Physical examination

palpation of the shoulder joint, range-of-motion testing, and localisation of pain

X-ray

evaluation of bone structure, joint alignment, and visible bone changes

Advanced imaging (CT / MRI)

assessment of complex fractures or soft tissue injuries

Blood and biochemistry panel

evaluation of overall health and surgical risk

Referral to a specialist clinic with advanced imaging equipment and orthopaedic expertise is recommended

04Treatment and home care after diagnosis: medications, diet, and management guide

Treatment ranges from conservative management to surgery; post-operative follow-up and rehabilitation are essential for recovery.

Conservative management: rest, restricted activity, and pain relief or anti-inflammatory medications as recommended by the vet
Surgical treatment: severe ligament or tendon rupture and complex fractures may require surgical fixation
Post-operative care: restrict activity, attend follow-up appointments, and follow the vet's instructions for wound care and suture removal
Rehabilitation: physiotherapy or passive range-of-motion exercises to support functional recovery and muscle rebuilding
Weight management and nutritional support can reduce joint stress and promote long-term wellbeing

05What to prepare before the vet visit: key information to help the vet assess quickly

Bring gait videos (front-view and side-view) with the recording time noted

Note when the injury or abnormality began and how it has progressed

Describe the location of pain, any swelling or warmth, and whether there is bleeding or an open wound

List all current medications, supplements, and any previous diagnostic reports

Use a sturdy carrier or soft stretcher and avoid moving the injured limb

Book an appointment at a clinic with X-ray or advanced imaging facilities for a thorough evaluation
