Precision Gait Analysis for Dogs
See what your eyes can't — catch mobility problems early.
See what your eyes can't.
Your dog can't tell you when something's wrong until it's serious. PAWSCHECK tracks subtle movement changes over time — catching early signs of arthritis, lameness and joint disease when they're still treatable, not when they're obvious.

Ten Months of Progressive Damage Between Appointments
You Can't Fix What You Can't Measure
Even the most diligent owners only see their vet once or twice a year. That's 2 days out of 365 — two brief snapshots of a continuously changing picture. Small changes in how your dog moves often begin long before a limp is visible.
of arthritic dogs are undiagnosed and untreated — seen as 'just getting old' or 'too young for arthritis.'
Annual Check-Up
Vet says 'looking good.' No visible symptoms in clinic
Weight Shifting
You don't notice - you see your dog every day
Next Check-Up
Vet says 'He has arthritis', you think 'I wish I'd known sooner…'
Ten Months of Progressive Damage in the Gap Between Appointments
Your vet isn't failing you. They're working with impossible constraints: a 10-minute window, a stressed dog on an unfamiliar surface, and no baseline for comparison. They're being asked to detect gradual change from a single frozen moment.
It's like trying to manage weight gain by standing on the scales once a year. You need the trend line, not the snapshot.
Peer-reviewed research: vets disagree on mild lameness 77% of the time, and visual assessment misses 64% of cases that instruments detect. (Keegan et al., 2010; Evans et al., 2005)
Your Dog Is Their Own Baseline
Research shows the majority of gait measurement variance comes from individual dog differences. Comparing your Labrador to some "average dog" is statistically meaningless. The only reliable comparison is your dog today versus your dog last month.
How Tracking Works
For early detection: First video establishes baseline → Every check compares to that baseline → Helps alert you to potential problems
For treatment monitoring: Video before treatment → Track response weekly → Objective data helps with treatment monitoring
For recovery tracking: Post-surgery baseline → Weekly progress videos → Share progress data with your veterinary team
Already Treating a Condition?
If your dog has arthritis, hip dysplasia, a cruciate injury, or is recovering from surgery - you need to know if the treatment is actually working. Not "seems better." Actual data.
Post-Surgery Recovery
Track improvement week by week after surgery for joint disease or fracture repair. Share objective progress data with your surgeon.
"Is she weight-bearing more this week than last?"
Medication Effectiveness
Track response to medications and physio programs. Help you and your vet team optimise your dog's treatment plan
"We started a monthly injection - is it helping?"
Chronic Condition Management
Monitor arthritis, hip dysplasia, or degenerative conditions over months and years. Catch flare-ups before they become crises.
"His chronic arthritis is well managed, but has it got a little worse this week?"
See Exactly When Treatment Started Working
Log medications, physio sessions, and supplements. PAWSCHECK correlates your treatment timeline with gait changes - so you can see exactly when improvement started (or didn't).

Summary for Pet Owners
This is a moderate limp.
Your dog has a moderate limp in the right front leg and shifting discomfort in the back legs.
What We Found
Affected Area: Right front leg and both back legs
Your dog's head rises when the right front leg hits the ground to avoid putting weight on it. Additionally, the way they use their back legs changes depending on how fast they are moving.
Your dog is showing signs of discomfort in multiple legs. The right front leg is consistently affected, but the back legs are also involved. They favor the right back leg while walking but shift that discomfort to the left back leg when trotting. This 'shifting' is a common way dogs try to balance out pain across their body.
What This Means
Pain: Your dog is likely experiencing significant discomfort, particularly in the front right leg and the knees or hips.
Daily Impact: This level of lameness will make long walks difficult and may cause your dog to hesitate before jumping or climbing stairs.
Outlook: Multi-limb issues are complex, but identifying the primary source of pain allows for a targeted treatment plan that can greatly improve mobility.

Clinical Overview
| Primary Affected Limb | MULTIPLE |
| Lameness Grade | 3/5 (AAEP Scale) |
| Grade Description | Grade 3/5 - Moderate lameness with obvious gait alteration and consistent head bob. |
| Confidence | HIGH |
All Limbs at a Glance
| Limb | Grade (0-5) | Status | Summary |
|---|---|---|---|
| Left Forelimb | 0/5 | SOUND | Sound limb used for weight-bearing compensation. |
| Right Forelimb | 3/5 | MODERATE | Consistent lameness with 'up on lame' head bob. |
| Left Hindlimb | 3/5 | MODERATE | Affected primarily at the trot (gait-dependent). |
| Right Hindlimb | 3/5 | MODERATE | Affected primarily at the walk (gait-dependent). |
Gait Pattern Description
The patient exhibits a complex multi-limb lameness pattern. The most consistent finding is a Grade 3/5 right forelimb lameness, characterized by a distinct head bob (head elevation during right forelimb stance). In the frontal trot, this pattern is rhythmic and persistent. Simultaneously, a compensatory forward weight shift is noted in the lateral view, evidenced by a lowered head carriage and a roached (arched) topline. The hindquarter analysis reveals gait-dependent bilateral involvement. At a walk, the dog exhibits a right hindlimb hip hike and shortened stance phase. However, at the trot, the lameness lateralizes to the left hindlimb, with a visible pelvic hike on the left and a shallower pelvic drop. This shifting lateralization, combined with the 'Law of Sides' (Right Fore/Left Hind diagonal), suggests bilateral hindlimb pathology—likely stifle-related—where the faster gait unmasks the contralateral side.
Bilateral Assessment
Pattern: BILATERAL_ASYMMETRIC
Bilateral Involvement: Yes
Details: Bilateral hindlimb involvement is suspected; the right side is more apparent at slow speeds, while the left side becomes dominant at the trot.
Note: The presence of forelimb lameness may be partially masking the total severity of the hindlimb discomfort.

Regions for Veterinary Examination
Areas the movement pattern points to: multiple · Confidence: Moderate
What the movement suggests: The consistent right forelimb head bob points towards the right elbow or carpus. The shifting hindlimb pattern (right at walk, left at trot) is the kind of pattern seen when weight is being redistributed between the hindlimbs. These are areas your vet may wish to examine — they cannot be confirmed without a physical examination.
Joint-by-Joint Assessment
| Joint | Left | Right | Notes |
|---|---|---|---|
| Shoulders | Normal | Normal | |
| Elbows | Normal | Suspect | Possible source of right forelimb lameness; needs palpation. |
| Carpi | Normal | Abnormal | Stiffness noted during stance phase. |
| Hips | Suspect | Suspect | Reduced extension noted in lateral view. |
| Stifles | Abnormal | Abnormal | Primary suspect for shifting hindlimb lameness. |
| Hocks | Stiff | Stiff | Likely compensatory stiffness secondary to stifle pain. |
| Spine | Roached topline noted | May be compensatory or primary lumbosacral discomfort. | |
Neurological Screening
No video-visible neurological signs (such as knuckling or paw scuffing) were observed. Video analysis cannot rule out neurological disease — only a physical examination can.
| Sign | Result | Notes |
|---|---|---|
| Paw Scuffing | ✓ No | |
| Paw Placement | CONSISTENT | Variable = concern |
| Stride Rhythm | REGULAR | Irregular = concern |
| Knuckling | ✓ No |

Clinical Considerations for Your Vet
Movement patterns that may warrant veterinary assessment. These are discussion points, not diagnoses, and cannot be confirmed without a physical examination.
| Area to consider | Why the movement raises it |
|---|---|
| Both stifles | Hindlimb pattern shifts between walk and trot — the kind of pattern seen with stifle instability. Your vet can assess with drawer and tibial-thrust tests. |
| Right elbow | Consistent right forelimb asymmetry with a compensatory head bob. Palpation and radiographs can assess for joint changes. |
| Multi-limb / systemic causes | Involvement of three or more limbs can accompany a multi-joint or systemic process worth considering. |
Other areas your vet may consider: Hip dysplasia, lumbosacral disease, panosteitis (if young)
What To Do Next
Suggested first steps
- Book a veterinary examination to interpret these findings
- Consider avoiding high-impact activity (jumping, fetch, stairs) until your vet has examined Chester
- Short, controlled lead walks in the meantime
Assessments your vet might carry out
- Orthopaedic palpation: including drawer and tibial-thrust tests to assess stifle stability.
- Radiographs (X-rays): of the areas above to look for bone or joint changes.
Ongoing management (to discuss with your vet)
- Weight management to reduce stress on the joints
- Pain management options such as NSAIDs
- Physical rehabilitation once your vet has reached a diagnosis
Follow-up: Your vet may advise re-examination within a few days if signs persist or worsen.
