For the dog parent who needs more than a basic GPS tracker, the Fi Series 3+ is your partner in proactive pet care. It's not just about finding a lost dog—it's about preventing escapes with custom virtual fences that alert you instantly if your pup leaves a safe zone, so you can act before a worry turns into a panic.
This smart collar goes beyond location tracking to monitor your dog's health and behavior. The AI detects activity, rest, barking, and even licking or scratching, giving you insights into their well-being right in the Fi app. You'll notice subtle changes, like increased scratching that might signal allergies, before it becomes a bigger issue. With Apple Watch compatibility and two-way audio, you can check in and connect easily, making it a tool for daily peace of mind and stronger bonds.
