Struggling to teach your canine friend? A quality dog training whistle can be an effective tool for teaching your dog to follow your commands, such as calling him to you, sitting or going in a new direction. The Ortz dog training whistle produces an ultra-sonic sound that is easier for dogs to hear. It takes a little bit of time, patience and practice, but your dog will learn to obey you through various whistle commands. Instructions 1) Adjust the pitch & blow the whistle to your dog. But even dogs can′t hear all frequencies (your whistle has a nut and screw that adjust the frequency when turned). You may want to wait until he is asleep and gently blow on the whistle. 2) Continue testing until your dog perks up. You will then know you have reached a frequency he can hear. 3) Use the dog whistle with varying sequences to train your dog. For example, one long burst can mean "come", while a series of short, staccato bursts might mean "sit". 4) Keep your whistle commands consistent and your dog will always know what you expect of him. Change your dog's behavior through training. For instance, at meal time, blow on the whistle before they get the food. It will only take a few attempts doing this before your dog gets good at it.
