With the PetSafe Smart Dog Trainer, you can train your pup right from your smartphone. Once you download the SMART DOG Trainer app, your phone becomes a remote that controls the training collar. You'll be able to push a button on your phone to send a signal to the collar. It can be set to deliver a tone, vibration or static correction, which is a light tingling sensation like you might feel when you walk on carpet and then touch metal. The PetSafe Smart Dog Trainer is great for teaching your dog to follow commands or to stop jumping, digging or chasing. The range for the collar is up to 75 yards, and it can be used on pets 8 pounds and up. It's rechargeable, waterproof and made for phones that are Bluetooth 4.0 compatible with iOS 5 or Android 4.3 or later.
