Does osteoarthritis in dogs and cats always require surgery?

Not necessarily. Most cases are managed conservatively with weight control, pain relief, and rehabilitation. Whether surgery is needed is determined by the vet based on imaging findings and clinical response. Ask your vet for personalised advice.

What diagnostic tests are commonly used for arthritis?

Physical examination and X-rays are standard. Blood tests, joint fluid analysis, or advanced imaging (CT/MRI) may be added to rule out infection or other causes of lameness.

How much does treatment typically cost?

Costs vary considerably depending on the type of examination and treatment chosen. Conservative management tends to be less expensive; surgery or specialist referral will cost more. Ask your clinic for a written estimate.

Are joint health supplements helpful?

Certain ingredients such as chondroitin and glucosamine may benefit joint health, though results vary between individuals. Always inform your vet and combine supplements with weight management and rehabilitation.

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 Emergency Care Immediately

•Sudden inability to stand or bear any weight
•Visibly swollen joint with open skin or bleeding
•Persistent lethargy or obvious confusion

Schedule a Clinic Visit Soon (within 24–72 hours)

•Noticeable limping but still able to walk briefly on their own
•Clearly flinches or cries out when the joint is touched
•Significantly reduced activity level but still alert

01What symptoms indicate a problem?

Arthritis typically presents with chronic or intermittent pain, reduced activity, and changes in movement. Symptoms may develop gradually or worsen suddenly.

Limping on one or alternating legs with a noticeably altered gait
Reluctance to jump, use stairs, or leap down from elevated surfaces
Flinching, pulling away, or vocalising when the joint is touched
Decreased activity, tiring more easily, or sleeping longer than usual
Weight gain or muscle loss, both of which place added strain on the joints

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden inability to stand or bear any weight
⚠️ Obvious joint swelling with skin breakdown or bleeding
⚠️ Persistent lethargy or noticeably altered consciousness

02How to assess at home: key observations and when to seek emergency care

Recording behavioural and lifestyle changes before your visit helps the vet assess symptom onset and severity, and speeds up the consultation.

Note when symptoms began, how they started, or when they worsened
Film at least 30 seconds of your pet walking from the front and side for the vet's review
Note which leg is being favoured and at what times of day pain seems worst
Record any changes in appetite, water intake, or toileting habits
Weigh your pet and note any recent changes in body weight or muscle mass
If possible, book an appointment at a clinic with X-ray equipment as early as you can

03How will the vet make a diagnosis? Common diagnostic tests

The vet will use systematic physical examination and imaging to identify the source of pain and the extent of joint changes, guiding the treatment plan.

Physical examination

palpation of joints, assessment of range of motion and pain response

X-rays

evaluation of joint surfaces, osteophytes (bone spurs), and bony changes

Blood tests

assessment of inflammatory markers and overall health status

Advanced imaging (CT/MRI)

evaluation of complex joint involvement or soft tissue changes

Joint fluid analysis

cytology or bacterial culture to rule out infection or other causes

Referral to an orthopaedic or rehabilitation specialist may be discussed if needed

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

Treatment aims to relieve pain, control inflammation, and improve mobility — typically requiring long-term monitoring and a multimodal approach.

Weight management and dietary adjustment to reduce joint loading
Short-term pain relief and anti-inflammatory therapy as directed by your vet, with regular follow-up
Physical therapy or rehabilitation (e.g. hydrotherapy, passive range-of-motion exercises) to help restore function
Surgical evaluation to discuss operative or other interventional options if required
Regular rechecks during or after treatment to monitor efficacy and side effects as advised by your vet
Bring your pain and activity log to each recheck so the vet can track treatment progress

05What to prepare before the vet visit: key information to help your vet quickly identify the cause

Prepare a symptom log noting the time of onset and how symptoms have changed

List all current medications, health supplements, and nutritional additives

Bring a walking video and any previous X-ray films or examination reports if available

Record any recent changes in food intake, water consumption, or toileting frequency

Transport your pet in a secure carrier and note any movement restrictions or pain locations
