Whistle has become one of the leaders in the GPS pet tracking world.
If you're thinking about getting one of these devices for your dog, there's really no better option than Whistle. Unless you live outside of the United States, this is your best option. If you do live outside the US, then read about Pod Trackers here.
In a world where almost everything can be tracked, and almost everything has an app, losing your dog should never happen.
You might not know this, but 1 in 3 dogs will get lost in their lifetime. When I heard that, I was shocked. But with today's technology, and specifically with a pet tracker like Whistle, you should never worry about your dog getting lost.
