1. Easy Training: Adjust the frequency by turning the screw rod inward or outward until your dog shows the most noticeable reaction. Once you find the right frequency, the Howan dog whistle helps your pet follow basic commands after training. 2. Safe for Pets and Owners: Made from robust metal and durable plastic, the Howan dog whistle is compact and comes with a complimentary black lanyard. It is safe for your dog’s hearing and harmless to humans. 3. Professional Dog Training: The whistle enables you to teach your dog or puppy a wide range of commands. From stopping barking to sitting, coming, lying down, recall, and even toilet training, mastering new skills has never been easier. 4. Adjustable Frequency: Different dogs respond to various frequencies. The whistle delivers a wide range of sounds between 5.4 KHz and 12.8 KHz when adjusted. This range is sensitive to dogs’ ears while being virtually inaudible to humans. Use scenarios: - Home obedience and bark control: training basic commands in a familiar environment and reducing nuisance barking. - Outdoor recall and training: effective cues during walks or in the park to improve responsiveness at a distance. - Puppy training and toilet training: establish routine cues for sit, stay, come, and appropriate indoor/outdoor behavior.
