The Verdict
Whistle has more features but it comes with a paid subscription. On the other hand, Findster Duo+ is subscription-free dog GPS collar which is the winning point, but it has so many customer complaints and they have recently discontinued the product. It depends on what features you want from the collar and the budget you are willing to spend to make your dog safe, but I would personally use Whistle because they have an unlimited tracking range and also a great battery. However, on top of these two, I would recommend Fi dog collar instead.
