So I thankfully haven't needed to use this for my DOG yet but I made my boyfriend "run away from home" to test it out. He was in a culvert tunnel a few miles away...like literally in the culvert with water in it...and this collar was spot on at telling me where he was. I opted to buy this over the whistle because the whistle makes you wait 3 minutes before they refresh the dogs coordinates.my dog could be anywhere after 3 minutes. I have a husky and he likes to escape the fenced in backyard and travel the town sometimes. This is going to be a lifesaver! The leather collar is really nice and I like that the tracker locks onto the collar. I am never worried about it falling off.

Mr Wrex likes to wander. He's a year old Labrador Retriever and he high energy. We had the collar on for 5 minutes when he took off. I was able to find him in the dark a full lake away. Worth the price and holds up in the water... his other favorite place to roam. Great for tracking our adventure too. Thanks LinkAkc

This device is perfect for what I was looking for! I have been in the market for a smart collar for some time now, and while I have done a ton of research on everything similar that is on market... this one BY FAR is better than the others, so I decided to pull the trigger. I have a small dog (12 pound Dachshund/Chihuahua mix) who, let's just say is a very curious one and seeks adventure. This means that he tends to sneak out from under us at times so the GPS function was the highlight for me... but I was so pleasantly surprised by all of the other functions that come in handy too. The remote light/sound function is AWESOME since I used to go and buy bicycle lights to attach to his harness when we went camping lol. Alerts for temperature and if he is away from 'Home Base'... also the Adventure function is a fun tool to use when we go to new parks and explore. It is easy set up and easy to understand, very user friendly. Another note is its size... I was worried a little bit about the fit and if it would be too bulky since my dog is very tiny, but it actually fits him quite nicely and doesn't bother him at all. For what it is, the actual 'smart piece' attaches right in and is pretty compact. Very happy and would recommend to anyone that has an adventurer on their hands!!

I received my dogs collar a few weeks ago. Impressively package and engineered the collar offers the flexibility I need. My dog, a chocolate lab is in the water at least five days a week. I moved the tracker unit from the rugged, attractive leather collar to my dogs water collar. This flexibility is a great feature for us. The 'electronics' of the unit are very impressive as well.

The collar tracks my dog's location on a close to real time display on a cell phone app. While my dog is not a huge roamer it is nice to know I can find her when she does stray. The light on the collar I find is very helpful for locating her quickly when I let her out at night. My neighborhood is very dark at night and this feature is probably my favorite.

If you have used a conditioning collar to help train your dog you will enjoy the 'sound' feature on the LinkAKC collar. While the 'sound' is different than that produced by my dog's conditioning collar she responds to it similarly. So it's a great plus for giving 'corrections' in your dogs training.

I am a big FitBit person and the activity tracker built into the collar works great to provide me with the insight I need to keep my dog's activity level where it should be. The algorithm the collar uses to calculate activity delivers a precise value base on your dog's breed, weight and age.

The temperature alert is also a great feature especially in the warm weather. Dogs in cars is a concern to me and most responsible dog owners. The alert let's you know when the ambient temperature reaches a threshold that you set. There is a setting for high and low temperature thresholds.

There are other features that I have not used including an away zone or safe zone that lets you know when your dog goes beyond a user designated boundary. I have talked with technical support and found them to be responsive and helpful. I might also add that when my dog goes swimming the tracker unit is submerged as it usually rotates around to the under part of her neck. I have had no trouble with the fresh water. I have not yet taken her to salt water which will happen later this summer.

With so many features I did not list all of them. Their website is well done and very informative and will detail all the features and pricing for the collar so, check it out! Good luck !

These collars are super sophisticated looking--with a name like Jean-Claude, our Frenchie must look classy in what he wears!

Our two dogs have very different temperaments, and I like that Link can help them in different ways. Mr. Bojangles, our English bulldog, is super lazy, a little bit older and would never ever run away from me and my husband but Jean-Claude is young, small and feisty. I like that for Mr. Bojangles we can monitor her activity to make sure that she gets SOME activity (she's so lazy!) and that we have a digital leash so-to-speak on little Jean-Claude. We live in a city, so having the light on the collars at night is great for our walks, especially for little J-C - he's not as easily seen as MB!

Seen some negative reviews on link - Yeah it's a little buggy and the app could use some more work but that's to be expected for v1 of any tech product. If you've ever worked in tech you can appreciate all that happens behind the scenes to make a product work (and this does work, just app can be glitchy sometimes). Already seen some subtle improvements on the app.
