You may not be aware but all pet trackers aren’t created equal. We want you to be aware of the differences when deciding what tracker is right for you and your dog. Many trackers (not including the Marco Polo and Garmin) require that you are in cell phone coverage areas to work properly. If you are like us and drive to remote hiking spots or travel on major highways (where just one mile off the highway you may loose cell coverage) the Marco Polo or Garmin systems will be best for you. But if you only travel within major cities are are only concerned about your pet leaving your yard the Whistle, TAGG and other cell-based trackers will work great for you. Many of the cell-based trackers also may require subscription fees. So shop around and find what’s right for you and your dog’s life.
