GPS Dog Fence for Multiple Dogs

I will forever recommend Fi collars. They only do GPS though and quite honestly, if your dogs are going through the effort to get out of a physical fence, they’re not going to care about a wireless fence. All tracking collars will have their pros and cons. Fi is not as quick to report a dog out of b

Update on the Ultra

We returned it for those reasons. Can’t use Fi app without cell service, thus can’t find dog if no cell service. We tried it on a hike through light/moderate tree cover and it did not work. Other gps devices (a Fitbit with standalone gps and also iPhone using satellite messaging) did work in the loc

Five month old Cattle Dog/Husky mix. We’re in trouble haha

Air tags don't make a good substitute for a proper GPS collar because they rely on phones being around them to function. If you're in an area that doesn't have a lot of phones, then you won't find your dog. And even if you are in an area with a lot of iPhones around, that doesn't guarantee you will

UPDATE: After 8 days, Joey the missing rough collie, has been found

Tractive was something I really looked into, but my parents ordered Fi since we’ve already had a Fi collar on one of our dogs and it's worked very well for us

Rooftop tent first time with dog

And an air tag will only work if other people with phones are near the dog. There are a few actual GPS collars out there now, like Fi, that would be more reliable for dispersed camping.

Fi Mini Silicone holder replacement

I have the Fi Mini on two Huskies and when I got them I couldn't believe that the best they could do was $0.02 worth of silicone for a holder. Had the same thought at the time and I went searching for a more robust attachment device. The third party holders seemed kind of spendy and fairly big with

Gos collar

I've tried tractive and Fi, and massively prefer Fi for 2 reasons: Durability - my two went through 6 tractive collars in a year because they like to wrestle and it would get smashed and because they seem to be able to find any mud puddle in a 50 mile radius and the mud would get in the circuits. We

Reluctantly considering coming back to the brand and picking up a series 3+ just for the battery life. Do current users think its worth it?

Fi’s claim to fame is battery life and size. Everything else is marketing fluff. The accuracy of the 3+ is good enough and it’ll get you within 15-20 feet of where the collar is on lost dog mode. It doesn’t provide up to the second location data because that’ll run the battery dry. It’s the best for

SpotOn Not Responding to Fence

This happened to me too. 2 acres in the Rockies, very rural. No cell service, only WiFi with Starlink. I had to bring the fence in about 10’ where the collar dead zones were. I also put it on the charger and turn it off every night as instructed by customer service. This did the trick and my dog has
