Smart GPS Collar for Everyday Dog Tracking
The Fi Series 3+ Smart Dog Collar combines live GPS location tracking, escape notifications and activity monitoring in one rechargeable collar. Connected features are managed through the Fi app, allowing owners to review their dog’s location and daily movement from a compatible smartphone.
This listing is for the Blue, X-Small variation and includes a 12-month Fi membership.
Live Location Tracking Through the Fi App
When connected to a supported network with an active membership, the collar can display location information through the Fi app. This can help owners respond more quickly if a dog wanders away from home or leaves a familiar area.
GPS accuracy, update frequency and availability can vary according to cellular coverage, satellite visibility, surroundings, device settings and service status.
Safe Zones and Escape Notifications
Fi’s geofencing feature lets users configure designated areas such as a home or yard. The app can send an escape notification when the collar detects that the dog has moved outside the established boundary.
Alerts are a supplementary safety feature and should not replace secure fencing, identification tags, a microchip or responsible supervision.
Daily Activity and Behaviour Insights
The collar records movement and activity patterns that can be reviewed in the Fi app. This information may help owners compare daily exercise, rest and routine changes over time.
Wellness Information, Not Medical Advice
Activity information is provided for general awareness only. The collar is not a veterinary or diagnostic device. Contact a veterinarian if you notice unexplained changes in your dog’s mobility, sleep, appetite or behaviour.
Built-In Light for Low-Visibility Conditions
An integrated LED light can be controlled through the app to make the collar easier to notice during evening walks. Reflective accessories and a handheld light should still be used when appropriate.
Rechargeable Everyday Design
The Series 3+ uses an internal rechargeable battery and includes the charging equipment needed for routine use. Actual battery life varies with GPS usage, network conditions, escape alerts, LED use and other settings.
X-Small Fit and Collar Adjustment
This product is the X-Small variation. Measure your dog’s neck and compare it with the manufacturer’s current sizing chart before ordering.
A properly adjusted collar should:
- Sit securely without restricting breathing
- Allow approximately two fingers between the collar and neck
- Remain fitted without slipping over the dog’s head
- Avoid rubbing or pressure around the throat
- Be checked regularly as young dogs grow
