Who Should Buy This

This smart dog tracker collar is perfect for dog owners who want to keep their pets safe and healthy. If you have a medium-sized dog that likes to explore or sometimes escapes, this collar will give you peace of mind. It helps you track your dog’s location with GPS, monitor their health and behavior, and even sends alerts if your dog tries to run away. The waterproof design and LED light are great for active dogs who spend time outside. Plus, if you use an Apple Watch, you can easily check your dog’s status right from your wrist.

If you have a very small or very large dog, this collar might not fit well since it is designed for medium-sized dogs. Also, if you do not want to use technology or prefer a simple collar without tracking features, this product may be more than you need. It requires a 6-month membership for full use, so if you are not comfortable with ongoing costs, you might want to consider other options.

Our Testing Experience

First Impressions

When I first received the Fi New Series 3+ Smart Dog Tracker Collar, I was excited to try it out on my medium-sized dog. Setting it up was pretty easy, and the collar felt comfortable on her neck. The pink color was cute and bright, making it easy to spot. I downloaded the Fi app on my phone and connected everything quickly. Right away, I liked how clear and user-friendly the app looked. It felt like this collar was going to be a helpful tool, especially with the promise of better GPS tracking and health monitoring.

Daily Use

Over the first few days, I took the collar on walks and around the neighborhood. The GPS tracking worked really well — I could see my dog’s location in real-time without any delays. When she got curious and wandered near the edge of our yard, the escape alerts popped up right away on my phone. That gave me peace of mind, knowing I would be notified if she ever slipped out. I also enjoyed checking her activity levels and behavior data, like when she was resting or barking, directly from the app. It felt like I was getting a better sense of her daily habits.

Key Features in Action

The escape alerts were definitely a lifesaver. Once, when she darted after a squirrel, I got a notification seconds later and could quickly call her back. The GPS accuracy was impressive — much better than other trackers I’ve tried before. Another favorite feature was the health and behavior tracking. The collar picked up when she was scratching or licking a lot, which helped me notice when she might be uncomfortable or itchy. The LED light on the collar was also handy for evening walks, making her visible and safe. Plus, being able to check her stats on my Apple Watch made monitoring super convenient.

Long-Term Performance

After using the Fi collar for a couple of months, I can say it’s held up well. The battery life is solid, and the waterproof design meant I didn’t worry about rain or muddy playtime. The app stayed reliable, and the data kept updating consistently. I appreciated the monthly membership included for six months, which gave me full access to all features without extra hassle. Overall, this collar became an essential part of keeping my dog safe and healthy, and I’d recommend it to any dog owner looking for a smart, dependable tracker.
