The gait app for dogs & cats · phone & tablet
Small changes in how a pet walks often appear months before a limp - or a diagnosis. PetGait™ is a mobile app that turns a short video on your phone or tablet into an early warning for joint, spine and nerve conditions.

The silent signal
Dogs and cats are wired to hide discomfort. Long before we notice anything, they quietly shorten a stride, shift weight forward, or hesitate before a jump. These changes are tiny, but they're measurable - and they're often the first sign something is changing inside.
~1 in 5
adult dogs are affected by osteoarthritis - many without a clear limp.
Up to 90%
of cats over 12 have joint changes on X-ray, yet few are ever diagnosed.
30 sec
of walking on video is all we aim to need to spot a change.
A mobile app, made for real life
No clinic visit, no wearables. PetGait™ runs on the device already in your pocket - at home, in the garden or on your daily walk.

Small change vs. Luna's baseline. Worth watching.
Opening the early window
Weeks 0-8
Slightly shorter stride, uneven rhythm, less push-off from one limb.

Months
The body redistributes weight. Other joints and muscles start working harder.
Later
Stiffness after rest, reluctance on stairs, skipped jumps - owners begin to notice.
Often too late
By now damage may be advanced and treatment options narrower.
What a stride can reveal
Each condition leaves its own fingerprint on movement. These are the early gait cues our models are being trained to recognise.
DogsHip & elbow dysplasia
Bunny-hopping hind legs, narrow stance, swaying hips.
Cruciate ligament injury
Toe-touching on one hind leg, shorter step on that side.
Osteoarthritis
Stiff first steps, reduced range of motion, slower pace.
Spinal disease (IVDD)
Wobbly or crossing hind steps, scuffed nails, hunched back.
Luxating patella
Occasional skipping or holding up a hind leg for a few steps.
CatsDegenerative joint disease
Shorter, more careful steps; avoiding jumps up and down.
Hip dysplasia
Stiff hind gait, less spring when moving from rest.
Diabetic neuropathy
Dropped hocks - walking flatter on the back legs.
Spinal & back pain
Low, crouched walk and a rigid, less fluid tail carriage.
How it will work
Walk your dog, or let your cat stroll across the room. 30 seconds on your phone or tablet - no collars, no sensors.
Computer vision tracks each joint and measures stride length, symmetry, rhythm and posture - right from the camera.
Regular check-ins build a baseline. When something drifts, you'll know early - with data to bring to your vet.
Our vision
A world where no dog or cat suffers in silence - where the way they move tells us what they can't, early enough to change the outcome.
We're building PetGait™ with veterinarians, researchers and pet owners, so that gait becomes as routine a health measure as weight or temperature.
Early access
Launching on iPhone, iPad and Android phones & tablets.
PetGait™ is designed to help you notice changes early. It does not replace a veterinary exam or diagnosis.
