Instead of using a handheld remote (like all of our other remote trainers), we’ve swapped it out for an app on your phone. Inside the app, you can customize whether you are right or left handed, and there’s also an option to make your most-used button bigger so you don’t have to hunt for the settings you use the most. The app remote offers audible tones, vibration and stimulation levels for a range of options in connecting with your dog. The Bluetooth® connection stays running in the background even while you use other apps, so you’re always right on time with a signal for your best friend. Simply charge your dog’s collar as usual, and as you plug in your phone at night you’ll be charging your remote, too! Your pet deserves the best. Trust PetSafe® to help keep your pet healthy, safe and happy.
