One of the best purchases I've ever made! Device has been flawless since I purchased from the Whistle website in March of 2020. I have been saved from losing my dog Piper multiple times solely due to my whistle and how accurate the tracking is. The company also regularly releases updates and the app has improved significantly in the time I've had the device, especially when it comes to tracking allergies and licking/scratching. One of the best purchases I've ever made.

Awesome Fitness/Health Tracker for Busy Dogs Bought Whistle collars as a gift for our three grand dogs and their parents. Also got the health/fitness/ location tracking apps. These keep track of WHERE our four legged family members are, what they are doing or not doing and what is happening health and fitness wise on a daily and weekly and ongoing basis. We have our watches and they have their Whistle collars and everyone’s taking a little bit better care of ourselves now that we’re getting feedback. The location trackers are terrific for peace of mind. These sync perfectly with iPhones. Pricey but totally worth it.

Whistle is our pacifier! We have Whistle to help locate our free range dog, Leo when we are leaving or going in for the night. It’s was a necessity when he was young and wild. Now that he’s 9 he doesn’t run off but we like being able to find him when needed. The activity reports are also interesting and comforting to get. I tell everyone who inquires about what the device on the collar does, that it’s our pacifier!

Don’t waste your money I bought Whistle for my 2 dogs and in less than a year the devices stopped working. I called them and they said that the only option was to purchase a new device since it was out of warranty (6 months warranty). I bought new devices for both of them and again both devices stopped working in less than a year after the purchase (8 months to be precise) and again I was told that the only option was to buy new devices for both of them. The second time the device was also not connecting with cell phone network so it never sent notification to my phone when they left safe place.

Eliminates the worry Been using a whistle with my large dog for almost a year and it's been indispensable! Instantly know how urgently he needs to go out and if/when my kids or dogsitters have been walking him. The step and health tracker provides more useful information than my spouse's fitbit. Most of all, when he escapes off leash we know where to look for him, esp. useful if a neighbor recovers him first and lets him in.
