With the Whistle Go Explore Pet Location Tracker, you don’t have to wonder if your pet is healthy. This pet activity tracker can monitor how many calories your pup burns during playtime. Additionally, the Whistle Go Explore tracks how far your pet walks and how long she is active. All of this information is based on your pet’s breed, age, and weight, so it’s specific to your furry friend. Furthermore, this pet tracker will notify you if your buddy leaves a designated area. You may have an escape artist dog who likes to jump the fence. Well, you’ll know when that happens if he’s wearing this pet monitor. Because this collar tracker is rated IPX8 waterproof, it’s fine if your dog takes it in the ocean or lake during his romps. And with a 20-day battery life, this tracker will keep an eye on your pup during your longest adventures.
