Wearables
The collar keeps measuring on the days your dog isn't with us.
Two measurement stays a year give us depth. The K9 Collar gives us continuity, heart rate, variability, sleeping respiratory rate, gait symmetry, sleep and heat load, read every night and carried to your wrist on the Apple Watch you already wear.
What it reads, hour by hour.
Six continuous signals, each one owned by the specialist responsible for that system. Hover the chart for a given hour, or choose a signal to see what drift looks like and what we do about it.

Respiratory · BREATH
Sleeping respiratory rate
The single most useful home number in canine medicine. Counted automatically every night instead of once a month by hand, it detects fluid on the chest days before a cough appears.
What counts as drift
- -A sustained rise above 30 breaths a minute while asleep.
What happens next
- -Same-day call from the clinical team, this is a triage signal, not a trend line.
Paired to the watch on your wrist.
The collar is the sensor; your Apple Watch and iPhone are the interface. Nothing asks you to open a dashboard to find out whether your dog had a bad night.
On the wrist
The K9 companion app puts a live complication on your Apple Watch face: last night's respiratory rate, today's activity against target, and a coloured dot when a signal has drifted.
Walks, both ends
Start a walk on the watch and the collar pairs to it directly, pace, hills, off-lead time and heat exposure are recorded for the dog while your own workout keeps recording for you.
Haptic nudges
A tap on the wrist when a medication window opens, when the day's heat index makes a midday walk unwise, or when the collar has been off the dog longer than four hours.
Your health app
With your permission, the dog's daily summary writes into your iPhone health record alongside your own, because the two of you share almost every walk.
The hardware.
Sensor module
Optical pulse and HRV, three-axis accelerometer and gyroscope, contact thermistor, barometric altimeter and GPS, in a 22 g brushed steel housing that sits under the throat.
Band
Woven olive webbing in five sizes, machine-washable, with a steel quick-release and a second D-ring so the collar never has to come off for a walk.
Endurance
Fourteen days of continuous sensing per charge, IP68 to two metres for swimmers and hydrotherapy, and a magnetic dock that keeps overnight coverage intact.
Coat calibration
Each collar is calibrated at the baseline stay against force-plate gait, echo and an in-clinic respiratory count, so the readings are anchored to your own dog rather than a breed average.
From collar to protocol.
01
Sense
The collar samples continuously and stores locally, so tunnels, kennels and rural gaps lose nothing.
02
Sync
It hands off to your iPhone in the background, no docking, no exports, no CSV files.
03
Read
Each stream routes to its system specialist: PULSE takes the cardiac data, BREATH the respiratory, STRIDE the gait.
04
Escalate
Drift against your dog's own baseline opens a case with the clinical team instead of a push notification you have to interpret.
05
Rewrite
Six months of collar data sits beside the panels at re-measure, and the protocol changes on evidence.
Collar data is your dog's record. It is used to run the program and reviewed in de-identified form with our thought-leadership partner at the University of Pennsylvania School of Veterinary Medicine; it is never sold. A wearable is a monitoring tool, not a diagnosis, every escalation is read by a licensed clinician before it reaches you.
Included with every membership.
One collar per dog, replaced at each annual renewal, with the companion app for iPhone and Apple Watch.
