What are the common causes of lameness in dogs and cats?

Common causes include sprains, soft tissue injuries, arthritis, fractures, and foreign body wounds. The exact cause requires veterinary examination and imaging to determine, after which treatment and follow-up can be planned.

What initial steps can I take at home?

Reduce activity and avoid jumping, record a gait video with the time of onset, and bring the video and medical history to the vet as soon as possible so they can decide on further tests.

What imaging tests are needed?

Common tests include X-rays to assess bones and joints; ultrasound or advanced imaging (CT/MRI) may be arranged if needed to clarify soft tissue or neurological concerns, as recommended by the vet.

How long is follow-up needed after surgery or conservative treatment?

Minor soft tissue injuries often require several weeks of monitoring; fractures or post-surgical cases typically need imaging to confirm healing after 6–8 weeks, and full functional recovery may take several months — follow-up visits should be arranged as directed.

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 hind limb weakness, unable to stand or walk
•Obvious limb deformity or bone protruding through the skin
•Heavy bleeding, severe confusion, or loss of consciousness

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

•Persistent lameness but still able to walk short distances
•Clearly flinching or crying out when the affected area is touched
•Decreased activity, reluctance to jump or use stairs

01What Symptoms Indicate a Problem?

Lameness or localised pain is the most common presentation. Observing changes in gait, how often the affected limb is used, and pain responses can help gauge severity and the need for veterinary care.

Intermittent or persistent lameness, often worsening during running or jumping
Reluctance to use the affected limb, or frequently holding the paw off the ground
Flinching, whimpering, or snapping when the affected area is touched or pressed
Reduced activity, reluctance to play, or unwillingness to climb stairs
Visible swelling, warmth, or abnormal texture at the affected site

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden weakness or inability to stand or walk in the hind legs
⚠️ Obvious limb deformity or bone protruding through the skin
⚠️ Heavy bleeding, confusion, or loss of consciousness

02How Do You Assess the Situation at Home? Key Observation Points and When to Seek Emergency Care

Recording key information and a short video at home before the appointment helps the vet identify possible causes more quickly and arrange appropriate tests.

Use your phone to record a short video of the gait from the front and side
Note when the symptoms or injury appeared and the circumstances involved
Observe whether energy levels, appetite, water intake, and sleep have changed
Check whether urination and defecation are normal and whether there is any blood
If symptoms worsen or persist for more than 48 hours, seek veterinary care promptly

03How Does the Vet Make a Diagnosis? Common Examination Steps

The vet will combine physical and imaging assessments to determine whether the issue involves bones, joints, nerves, or soft tissue.

Physical examination

palpating joints and muscles to locate the source of pain

X-ray

assessing fractures, joint deformity, or dislocation

Ultrasound

evaluating tendons, ligaments, or joint effusion

Advanced imaging (CT/MRI)

used for complex fractures or neurological concerns

Blood tests or tissue sampling

to rule out systemic issues such as infection or tumours

04How Is It Treated and Managed After Diagnosis? Medication, Diet, and Care Guide

Treatment depends on the underlying cause. Whether managed conservatively or surgically, follow-up care according to veterinary instructions is essential to adjust the care plan effectively.

Mild sprains or soft tissue issues may initially be managed with rest and pain control
Clear fractures or structural instability require further surgical evaluation and stabilisation
Restrict activity and gradually increase weight-bearing and exercise as directed at follow-up visits
Schedule follow-up imaging or functional assessments as advised to confirm healing
Bring records of pain and activity changes to follow-up appointments; referral to a specialist may be recommended if needed

05What Should You Prepare Before the Vet Visit? Key Information to Help the Vet Identify the Cause

Bring a gait video recorded from the front and side for the vet to review

Note the time and possible triggers of the injury or onset of symptoms

Mark and photograph the suspected area of pain or swelling

Bring previous X-rays, examination reports, and a current medication list

Use a secure carrier or lead and avoid letting your pet sustain further injury
