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.

Too big!

I was excited to get this in the email but was horribly disappointed to see it was TOO BIG for my Chihuahua.

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.💛🐶🐾💛

Don't care about the activity

I use this to check on my dog when I am away. All I care about is the gps tracking, pls stop telling me about my dogs steps or activity. I don't care about that, just give me a map.

Love this collar!!

Love this collar!! We got one for our dog, he has a tendency to chase things... like birds. Our property is huge and we were afraid we'd lose him in the middle of nowhere. But with this collar we had the peace of mind knowing we'd find him. It works great. Even counts their steps. Discovered we have a lazy dog due to that feature. Lol Great product. Very classy sleek looking collar too. 😁 Thank you!! 😁

We run a pet Search and Rescue, and when we recover the lost dogs, we always recommend they purchase a Fi collar.

Helps with our 14 year old deaf Terrier

Last winter I bought my 14 1/2 year old Terrier Mix a Fi Collar. It has been the best thing I did. She isn't really an escape artist. We live on almost 6 acres and she is now deaf so. It has totally given me peace of mind knowing where she is on our property. I have attached a bell to her collar so that we can hear where she is. I would recommend this collar to anyone. I wish I thought about getting a GPS collar way before this. Fi is AWESOME.

Best investment for our pet!

Love this collar! It works great. Our German Shepherd took off after a deer and we were able to track him very easily. Best investment for our pet!!

Found my huskies in minutes

I was able to find my huskies within 10 minus of realizing they had escaped (they had been gone for 25 minutes) thanks to their Fi collars. We bought these a year ago hoping this would never happen... But yes, peace of mind. Thank goodness for GPS collars!

Great GPS just needs better stats

I wish the app had more stats for my dog but overall a good gps collar with a neat light feature on it.

Dog went for a neighborhood stroll

I have had this for about three months. I didn't really get it because my guy is a runner. I thought it was cool! Well the in-laws let him out the other day and he took advantage. I got the notification he had left the house. I made a few phone calls and he was missing. Pulled up the app. He was on a neighborhood stroll. Pointed the in laws in the right direction and he was found shortly. Fi!

Thank you

I just wanted to tell you guys thank you for what you do to keep our furbabies healthy and know where they are via gps tracking. I live near a small downtown area and I'm always afraid of my girl getting out. She jumped my fence and I found her within minutes of my notification thankfully unharmed. I spent the day making repairs to my fence to make sure she will always be safe. Thank you guys. I've only had the collar for two weeks and I bought it for her birthday. Zara is safe and home.

Too much tracking

The app does fine tracking my dog BUT it requires that you allow it to know your phone's location! I'm tracking my pup not myself!!!!!
