FreeStyle Libre 3 Plus Sensor for Dogs and Cats – Continuous Glucose Monitoring Device

The FreeStyle Libre 3 Plus Sensor is a compact continuous glucose monitoring (CGM) device used in veterinary patients to monitor glucose levels in diabetic dogs and cats. It provides real-time glucose readings without the need for repeated blood sampling.

The sensor measures glucose levels in interstitial fluid and automatically transmits readings to a compatible smartphone using the appropriate FreeStyle Libre app. This allows glucose trends and patterns to be monitored throughout the day and night without needing to scan the sensor manually.

Its small, low-profile design can be particularly useful in cats, smaller dogs and patients where a larger sensor may be more difficult to keep in place.

Wear time in veterinary patients can vary depending on placement, adhesion, coat preparation, activity level and the individual patient.

FreeStyle Libre 3 Plus vs FreeStyle Libre 2 Plus

The FreeStyle Libre 3 Plus is smaller than the FreeStyle Libre 2 Plus and automatically sends glucose readings to a compatible smartphone without requiring the sensor to be scanned.

Both devices can be used to support continuous glucose monitoring in dogs and cats under veterinary guidance. The most suitable sensor will depend on the individual patient, sensor placement and device compatibility.

Important Information

This is a human medical device used in veterinary patients.

Use should be discussed with and directed by a veterinary surgeon.

Accuracy and wear time may vary depending on sensor placement, adhesion, coat preparation, movement, skin condition and individual patient factors.

Glucose readings from interstitial fluid may not exactly match blood glucose readings, particularly during periods of rapid glucose change.

A compatible smartphone, app access and account setup may be required. Compatibility should be checked before purchase.
