Terrible since Whistle took over Tagg

I was an original Tagg user and when Whistle bought them out, the new app is terrible. I bought Tagg for the sole purpose of tracking my dog when he went too far and being able to simply mash "my location " and be able too see where I was in relation to him so I could find him quickly and now you can't. If you need an app to tell you when your pet needs to exercise, be fed, or given medication then you probably don't need it. The map screen is now way too small and it won't always show me where I am. We live in the woods so that is a necessity. And not to mention they jacked up the monthly price. You also have to wait forever to o get anyone on the phone when you need help. We would change in a heartbeat if there was a different tracking collar in this price range.

Whistle killed Tagg

Original Tagg tracked my dog the moment he left the "zone". Then Whistle bought them out and now I have a "Fitbit" for my dog. Tells me he met his "exercise goal" from yesterday.😕 No longer notifies me during a breach. If I already know he's out, and request a locate, sometimes it will say he's still at home, sometimes it will locate but can take 10-15 minutes after your request. A Vizsla can be miles away in 15 minutes "after" you realize he's gone. Been reset and hard booted several times and on the phone too and even they finally replaced with a used unit that showed 8 previous home stations had been paired with it. Refurbished? Doubt it because the "new" one doesn't work either. Save your money. Cancelling after over a year of frustration. I wanted this to work SO Bad! Disappointed.

Whistle is a must if you have a dog that doubles as an escape artist...

Two years ago we adopted a rescue Lab who loves to break out of the yard and go for a long run in the neighborhood. Whistle has been a godsend in tracking him down and getting him home safely.

The Whistle battery also holds a charge longer than our previous Tagg collar unit. We find the recently-redesigned interface is easier to use, especially when you're in the first few moments of panic when you realize your dog has bolted from the yard.

We recommend Whistle to ensure a better chance of bringing your dog home safe and sound.
