Almost lost one of our pups today. So they are getting some tech this Christmas to ensure we don’t go through that again. These seem simple and effective with I believe a low $6/month service. They are currently on sale directly through whistle.com discounted at $49/each. Includes real-time GPS tracking and statistics on your pet’s behavior. Really excited to have this piece of mind finally, we put this off for so long but dogs are just as part of the family as anyone else in my opinion and worth the small investment to keep them safer.
