Description The SMART DOG Trainer is our techiest option for remote training. Instead of using a handheld remote (like all of our other remote trainers), weâve swapped it out for an app on your phone. Inside the app, you can customize whether you are right or left handed, and thereâs also an option to make your most-used button bigger so you donât 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 youâre always right on time with a signal for your best friend.Simply charge your dogâs collar as usual, and as you plug in your phone at night youâll be charging your remote, too! Your pet deserves the best. Trust PetSafe to help keep your pet healthy, safe and happy.PRODUCT DETAILTrain your dog from your phoneâPetSafe SMART DOG app is compatible with iOS 8, Android 5 or newer 75-yard range for inside or outside your home Waterproof collar (because what dog doesnât love puddles?)
