It always sounds a little “preachy” to list the steps to take before a dog goes missing in an article about finding a lost dog but in this case, if you are going to take advantage of using GPS trackers for dogs, the GPS collar will need to be on the dog. Most GPS dog collars are designed to have batteries that last for several days – if possible, leave your GPS dog tracker on the collar even though you are not actively tracking your dog. Some dogs are opportunistic, and will bolt out an open door (perhaps family has arrived and opens the door as they normally do), and if the GPS tracker isn’t on the dog….it won’t be able to help find him. Recharging dog tracking collars should usually take place at night, while you and your dog are sleeping.

The Garmin Astro Dog GPS system shows you exactly where your dog is. The Astro has the same range limitations that tracking collars have because radio signals will only go so far. As long as you can pick up the signal, you know the exact distance between you and your dog and what he is doing (pointing or running).ONE DOG -- A one dog Garmin Astro GPS system is $599 and additional Dog GPS units are $199 each (free shipping applies). While the GPS is slightly more expensive than a 1-dog bird dog tracking collar (around $499 depending on model), these tracking collars are not easily expanded when you need to track more dogs. You have to send your tracking collar back to the factory for an upgrade.
