The Fudini Collar · In development

The collar that learns their normal.

Your dog can't tell you they feel off. Fudini learns their own routine — eating, sleeping, moving — and tells you when it drifts.

The Baseline

Silence
means
nothing
changed.

We don’t overwhelm you with raw data. Fudini checks your dog’s behaviour ten times every six hours. If everything matches their normal baseline, we stay quiet. We only speak up when something drifts.

No alerts is a good day.

4 Behaviours

Four habits.
One normal.

Our neural network runs on our servers, classifying data from the collar. We track four core pillars of your dog's day to build their baseline over weeks.

You didn't
notice.
Fudini did.

Tiny shifts in routine are easy to miss. Fudini catches the subtle trends that happen while you’re working, sleeping, or just living life.

The Night Shift

When the house is quiet, the collar keeps listening. This is when drifts often first appear.

Example Alert

"Milo has eaten less and slept more than his own usual, three mornings running."

GPS won’t tell
you if they
feel off.

Most dog wearables are built around GPS — for the day a dog gets lost. We're building for every ordinary day: learn the baseline, flag the drift, skip the GPS.

Fudini will not find a lost dog.

Questions

Clear answers.

What you need to know about Fudini.

Does it replace my vet?
No. Fudini does not diagnose or treat illness. It flags behavioural changes so you can have a better conversation with your vet.
Can it find my lost dog?
No. Fudini does not have GPS. It tracks motion and habits, not location.
How much does it cost?
Fudini is currently in the prototype stage and not for sale. The early list is completely free.
Do I need the collar to use the app?
No. The Fudini iPhone app is live and useful today, even without the hardware.
Will you sell my data to pet food brands?
Never. Our food matching tool uses published manufacturer data, with zero sponsored picks.
