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.

Best collar I’ve invested in
This thing is phenomenalI can’t even count how many times my husky has gotten through the fence.Since I got this collar it’s been less of a stress when she does get outAt this point the whole neighborhood knows my dogIt has a slight delay when initiating lost mode when the connection is bad on your phone but honestly it’s worth every pennyYou can share the lost mode with others and they can help you find your dogThey will also be able to track her movementsIt does more like gives stats on health and movements.Tracks the walks too whenever you walk your dog with the exact outline of walk historyEverything is date and time stamped aswel

High Quality Collar with great metrics
excellent product.perfect for my Siberian Husky pup. Charge lasts forever as I’ve only charged it once in 2 months. App installed easily too. Would highly recommend.

Surprised my Frenchie needed the Medium Size, but great quality!!
Just bought the Medium size for my 17 lb Frenchie. I was adopting and had to order a collar without having my dog available for measurements. I originally thought either the XS or S would fit my dog, but the S (10.5 – 13” neck size) was too tight. I was surprised that I ended up returning the S and had to buy the Medium.Seems like a quality collar, my trainer uses Fi collars with GPS on the dogs she is training. Now that I’ve used the collar for a couple of weeks I can appreciate the elegant design and very high quality and functionality of this collar. This is expensive, but a great value and great piece of mind knowing the gps would help me track down my girl if she gets lost. I would buy this again in a heartbeat & i thoroughly recommend!!

My feral girl, Tito with pink fi 3+
We moved our feral cat, Tito to our farm but unfortunately she kept running away. We quickly discovered the ring collar tags do not work well in the country without WiFi. I opted to try Fi 3+, suited her up with a pink collar for some peace of mind after moving her back to our home at the beach. Fi works fairly well, but sometimes looses connection when she’s outside. I’ve found if you turn on lost tracking, it quickly drains battery when she’s outside. However, it is Interesting to track her adventures out exploring. Sometimes past tracking on app isn’t documented and is extremely slow to load. I purchased the standard size Fi 3+ because of the extended battery time. Easy to set up and seems durable to date. Just hope they make some lag time updates that will fix accuracy of locations current and record all past travels. Sometimes it drops off and isn’t available.

Would be the best on the market if their management wasn’t running the company into the ground
First and foremost, why I bought this product instead of comparable competitors; My dog is like an octopus, even though he has 36 inch chest, somehow he can squeeze through a 5 inch hole in the fence. All of the competitors are clip ons and would instantly be left behind. This one is a slim metal casing that doesn’t get caught in the process of escape. THE WHOLE POINT is tracking after escape.What sucks about this product is I had 2 duds in a row. Waiting on the 3rd via RMA. Both just stopped working about week 2. What also sucks is their complete lack of customer support. If you call, you get put on hold for an hour then hung up on. If you’re lucky you get a followup email half the time. They respond to emails after about 2-3 days. The response you get is the same useless phone-tree call center crap we’ve all experienced from terrible companies the last couple decades.They would have a top tier product if it actually worked, and the whole company wasn’t so terribly mismanaged.One final point, their “AI” “health statistics” are about as accurate as a random number generator. I wrote down the scratches, drinks, eating, etc. And they don’t match up even remotely with what the app says.Update: app crashes immediately now and the 3rd device also doesn’t work AT ALL.

Easy to use, Great information EXCELLENT customer service.
This product has given my wife and I peace of mind while at multiple safe zones. Our 4 month old malinous/german shepard mix, loves to run and play with other dogs and with GPS, we always know where she is. It was easy to set up, fun seeing her stats vs others of her breed, and Fi sends good dog training information. The new 3+ knows when the pet is leaving a safe zone with a shared owner. Excellent upgrade over the 2, my daughter just upgraded her dog’s collar after he lost his collar, Fi helped put her new Fi on her account and it came ready to collar.

Know where your dog is anytime
Love Love Love this thing it helps us keep track of where my dogs are. I have one for each dog. We had the fi mini and the attachment system was not good enough for my rowdy dogs. So we switched to the collar and wow it’s so nice and the batteries last a few weeks between charges
