PetSafe Collarless Ultrasonic Remote Dog Trainer

PetSafe Collarless Ultrasonic Remote Trainer leverages dogs' unique range of hearing by emitting a sound that is outside the realm of human ears. The ultrasonic frequency produced is safe, but just irritating enough to get your fur baby's attention and let them know you mean business. This training system allows you to choose between positive and negative tones, so you can let your dog know when they've done a good job or discipline them when they do something you don't like.

Features:

• Gives the option of using negative or positive tones for more versatile training
• Emits ultrasonic sound that's inaudible to humans
• Remote has a 9-metre (30-foot) range
• Works with dogs of any size
• No collar required
