The guys over at Whistle are upgrading their “fitbit for pets”. You can now know where your dog is at all times.

Whistle was originally designed as an activity monitor for pets. Basically you can see any spikes in activity during the day, or know if that walk you took Fido on was really beneficial for him. Now they are adding GPS to their device. Considering that over 10 million pets are lost each year this is a great idea.

The Whistle device attaches to your pets collar and can record location, rest and activity. So you will still know if your pet is getting the right amount of activity everyday. They claim that the Whistle/GPS is the smallest device of its kind on the market and also has the longest battery life. You will be able to use it for about a week before having to recharge.

As of right now, it looks like you can pre-order one of these for $49, but that price will be going up in the next few days to $130.00. The downside, it won’t be ready for shipping until summer 2015.
