Has your poodle ever run away from home?
We have a Fi collar and it has worked well thus far, as far as peace of mind. It stays charged for weeks, uses GPS or cellular networks to track all the time, and alerts us if our pupper leaves the yard. The company also works with a few other dog collar companies so their device can be put on diffe

3rd Post Today (By Me) Regarding Crappy GPS Tracking - Read this from 7 months ago
The post above explains it. The fi collar is designed to last for weeks/months that is why it updates less. Until you put it in lost dog mode. If you want second by second updates there are collars for that but they are huge and have to be charged every day or two.

Dog ran away today. Do I want a Fi, or…?
Fi’s advantage is that it’s the size of the buckle on the collar and the battery lasts for weeks. Most dogs go on personal quests exactly when you least expect it (you now know that). Because the Fi collar is on 24/7 they can be easily found when that happens.

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?
See my post on 3+ vs 3 battery lifehttps://www.reddit.com/r/FiDogCollar/s/W3jrCtZ04A Also, I think Bluetooth to phone or base is the most efficient.

Tracking collar recs?
I have the Fi collars on both my dogs. I like that it also gives me info on their activity levels and sleep patterns. I have one of the old style ones on my older dog that you need a special collar for and the newer style ones on my puppy that can be used with any collar. The batteries last a long t

What is the best GPS dog collar for dogs, and how do you choose the right one?
I stated facts to the reason the fi collar battery lasts longer which you claimed. I also specifically stated you can set it to lost dog mode which updates more constantly. You’re the one being difficult. You can’t use a fence feature if the gps is updating every 5 minutes.

Is it worth to buy Gps Dog Collar or Leash?
I have a Fi collar for our dog. It works well, app is good, batt life is OK but it runs down fast in "lost dog mode" (48 hrs from a full charge.) It has a cellular modem and gps so way better than an airtag i think. It does give me peace of mind.

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.

Has anyone used a Fi collar or other GPS collar?
I have the Fi mini for both dogs (mine are about 9lbs). I like it. I charge it about once a week and mine are active little mofos. Like top ten in our city active. Personally my dogs wear their collars 24/7 but we use harnesses for walking. Their minis are on their collars

Tractive 6 experience?
I use Fi for tracking my dogs; it works fine and has decent battery life if you have a base where the dog spends most of their time. Many of the major equipment companies either have Fi attachment support on their equipment or are willing to add it for a small fee. Size is hardly noticeable on a dog
