Now building — Tiers 1–4 in active development

Glucose monitoring for dogs, built by integration, not invention.

Aegis & Fur combines already-proven, already-cleared medical hardware into one platform that scales from free manual logging to full continuous monitoring — instead of spending years building a new biosensor from scratch. Every tail deserves a guardian.

Opens the real dashboard, not a mockup — running on a synthetic dog named Bella, API key pre-filled, reseeded automatically. Nothing you do there is saved to a real dog.

The Approach

We are not a biosensor company.

Designing a new glucose-sensing element is a multi-year, capital-intensive, regulatory-heavy undertaking — and doing early iterations of that on a living animal is a real safety problem, not a corner worth cutting. Aegis & Fur's engineering goes into the layer above the sensor.

Every sensor in our platform is an already-manufactured, already-cleared product designed for human use — applied thoughtfully to dogs, not reinvented from zero. Our own work is the calibration engine, the trend analysis, the hypoglycemia early-warning system, and the bridge hardware that connects proven sensors into one coherent platform.

That's a systems-integration problem, and it's the one we're built to solve well: take what already works in human medicine, verify it rigorously, and make it accessible for the animals who need it too.

  • ✕ Inventing a new biosensor from scratch
  • ✓ Integrating FDA-cleared, mass-manufactured sensors
  • ✕ Locking owners into one expensive hardware path
  • ✓ A tiered ladder from free to full continuous monitoring
  • ✕ A dosing calculator that tells you what to give
  • ✓ A formula reference, gated behind real comprehension checks, that always defers to your vet
The Product

Four tiers. One platform.

Every tier feeds the same trend chart, the same calibration engine, and the same hypoglycemia-drop alert logic — an owner can start at zero hardware and move up without switching platforms or losing history.

01

Manual Entry

Live

Type in a reading from any glucometer you already own — or take a photo and let a local vision model read it for you. No hardware required.

Auto-Capture

Firmware built

An Aegis & Fur bridge board auto-captures every reading from an ordinary Bluetooth glucometer, built on the public Bluetooth SIG Glucose Profile.

Partner Sensor

Live

Historical trend logging synced from a Dexcom Stelo sensor via Apple Health — transparently labeled as delayed data, never presented as real-time.

Aegis-Owned Stack

Firmware built

Real-time continuous monitoring — our own bridge hardware talking directly to an open-protocol sensor, no third-party app, no delay.

See It In Action

An actual glucose curve, not a stock chart.

This is real chart-rendering logic pulled from the live dashboard, plotting a realistic day for a diabetic dog. Hover any point for the reading and time — target range shaded, nadir and post-meal rise both visible, exactly what a vet reads a curve for.

Real Data

What canine diabetes actually looks like.

Every figure below is cited to a real veterinary source. Where studies disagree, we show both rather than pick the more convenient number — this is exactly the kind of thing that shouldn't be softened for a pitch.

90.1%
of insulin-treated dogs survived past 7 days post-diagnosis, vs. just 17.5% of untreated dogs
Niessen et al., UK primary-care study, n=409 (95% CI on treatment effect, p<0.001)
0.2–1.2%
of pet dogs are affected — roughly 13 per 10,000 dog-years overall, up to 24 per 10,000 in Poodles specifically

Survival time after diagnosis — the honest, unresolved answer

Two real studies give meaningfully different numbers, and neither should be quoted alone: a UK primary-care study found a median survival of 15.6 months from diagnosis (20.2 months for dogs who survive the first week), while an Italian specialist veterinary-hospital study found a median of 964 days — roughly 2.6 years. The gap is likely explained by care setting and case mix, not a contradiction in the disease itself — general practice sees a broader, less-selected population than a referral hospital. The veterinary field itself has published on whether current data is even adequate to counsel individual owners — this isn't a number Aegis & Fur is smoothing over, it's an open question in veterinary medicine.

What actually moves the needle

Real, cited risk factors: age 10+, Cocker Spaniels specifically, high blood glucose at diagnosis, and prior steroid treatment are all associated with worse outcomes; neutered status and (in one study) Border Collies specifically were associated with better ones. Notably, diabetic ketoacidosis at diagnosis was not significantly associated with survival in the largest study reviewed — a genuinely scary-sounding presentation doesn't automatically mean a worse long-term outlook.

Who's more likely to be affected

A 2025 UK diabetes registry found dramatic breed skew: Samoyeds are roughly 23.5×, Tibetan Terriers 11×, and Dachshunds 11× more likely to develop diabetes than baseline. Unspayed female dogs are roughly 2× as likely as males — most cases are adult-onset, not tied to a heat cycle, but a real minority (~10%) are.

Beyond Dogs

The same platform, a bigger problem.

Nothing in the core platform — calibration, trend analysis, hypoglycemia-drop alerting — is dog-specific; only the presets are. The same architecture that monitors a diabetic dog applies directly to cats.

This is stated as direction, not a near-term commitment. Our roadmap today is scoped to the canine product; expansion follows once the tiers above are proven with real dogs and real vets.
