Never hiccupped once

I just experienced a three-dog jailbreak. And they had at least fifteen-minute head start on me. Escaped through three open doors. Massive failure on my part. I grabbed my phone and opened Fi, and initiated Lost Dog Mode. Immediately I knew which direction to head. I was amazed at how far they'd gotten. Only our Husky had a tracker, but the other two were right behind her. Within minutes I had them in sight. I got a hold of the Beagles right away. The Husky decided to play games. Fortunately, she was distracted by another dog down in the campground they were traipsing around in (and oh yea, they went for a lake swim, too). With Husky in hand, we haded home for treats. Fi never hiccupped once. I had immediate location updates, even with very hilly terrain and trees. Fi proved itself today!

Great product

This morning my Catahoula/coon hound mix, Chai, took off after a deer. We found her in 15 minutes, about 1.5 miles away, thanks to her Fi collars. Thank you, Fi, for your great product and your superb customer service!

Highly recommend

We went down to the beach for a few hours and when we got back in the car I noticed my phone had many missed calls and messages about a cute dog roaming the street with my phone number on her tag - and these messages were hours old. My heart sank 💔. When we left her she decided finding her family was more important than a new ham bone and jumped through the balcony to find us. Loba wears a Fi-collar. The rescue we adopted her from actually gave us one. I am SO glad they did. I opened the Fi-collar app and had her exact, real-time location within seconds. I marked her as missing and I had her back within minutes. You can bet I'm now a huge advocate for this collar. If you have a dog I highly recommend looking into them.

Helped me get my escape artist back!

This is the best! I got it for my dog in December because he's an escape artist... today I was at work and I got an alert that my dog left home... because of that I was able to call the other people in the house who had no idea and they got him for me.

Saved me again

So fun! Love @fi.dogs, saved me again just today when my (4 day post-spay surgery) husky decided she had enough rest and needed a run! Found her in less than 2 mins with her Fi! Could have taken much longer and possibly injured her healing area if it wasn't for her Fi Collar.💛🐶🐾💛
