WUZHOU Clear Signals: The spoon allows the dog to receive clear signals and commands at all times. Even the loud background noise from highways and construction sites won't drown out this high-pitched dog whistle. Communication between you and your dog becomes clearer and easier. A high frequency dog training whistle is frequency standardized, which means that no matter who is using the whistle (e.g. partner, child), it will make the same sound regardless of their emotional state. Even if you lose your whistle, you can simply reorder it and it will have the exact same pitch as before, so your dog won't have to adjust to the new pitch. Fashionable Colors: Dog whistles are available in many different beautiful colors to suit every outfit and occasion. Each family member can choose the dog whistle that works best for them based on their preferences, and every whistle sounds the same. Training: Whether you want to go hunting with your dog or just want to call him in on a walk, start whistling training early. Key Ring: The whistle can be easily hung on a key chain or a separate whistle strap via the metal ring. This way, you always have your most important tools with you when walking your dog and minimize the risk of losing your dog whistle. Quantity: 10 pieces Size: 8*1.4cm Random Color
