I just found this dog in Huntington near home depot. No info on the collar.
FYI Dog will NOT be put down! They hold them for a certain number of days but that’s an expensive tracking collar — the owner is certainly going to come for them! If it starts blinking red then they’ve activated lost dog mode. It might be dead if you can put it on a charger. I’d bring to west hills

[Release] Fi releases Fi Ultra - the first tracker powered by T-Satellite with Starlink - AMA
Ok so when camping in a remote area for 4 or 5 days without electricity, youre saying it wont last? Also its like an addition to the regular fi tracker, not a replacement? This would be what I was looking for because me and my boy are always hiking and camping in remote areas but trying to keep trac

Location Mandatory for Collar?
This is probably my biggest complaint about the app, and I’ve commented on it here several times before. Simply knowing whether or not the dog is with you should only require a Bluetooth connection to the collar, not location. The walk tracking feature needs location since it uses the phone for that

Updated step tracking?
In another thread about this there's a pinned comment stating they know they messed up and are correcting the issue. On my 50 lb dog's 2.5 mile walk last night he got 1.5k steps, did the math and each of his "steps" were 9 ft. See pinned comment here https://www.reddit.com/r/FiDogCollar/s/25bNDF2Ka1

3rd Post Today (By Me) Regarding Crappy GPS Tracking - Read this from 7 months ago
As someone said in that link you provided: "You phone was reporting a location and your watch was reporting another set of location. Strava on your watch is designed to report at very frequent intervals and kills its battery very fast (you likely recharge your watch every day). Your Fi collar is aim

Your lost dog can now call home with the world's 1st satellite-connected dog collar
5 day battery life and its a clip on device. Collars, lights, tags, and other accessories get snagged all the time on dogs. Also, you cant track your dog without your cellphone having cellular service. So if you become separated from your dog in a TSAT only area, you cant track them. Its also an add

Lost my dog
I hope you find this baby. I am sorry you are going through this. I put an AirTag on my dog's collar and it's already saved us once. I recommend this as an alternative to the super expensive GPS dog collars (like Fi)

Processing the loss of a baby is extra difficult with today's dystopian automation in marketing.
I am so terribly sorry for your loss. Not a human, but still - I lost my dog. I had a Fi GPS collar for her - I canceled the service [on the phone, talking to a person] when she passed. Informed them that she had passed, I no longer needed the service, etc. A month later I got an email about re-acti

Advice Requested: tracking quality of walks with my dog sitter via Safe Zone
I noticed that my WiFi is strong enough that both the Fi Collar and my phone stay connected until I’ve passed 4 or 5 houses and cross 1 street while walking my dog. This causes our walks to start not at my house but down the street for some reason. I would think the walk should start when we leave t
