Here's why they are not painful:
* Dogs have a wider range of hearing than humans: They can hear sounds at much higher frequencies than we can. This is why they can hear the dog whistle, even if we can't.
* The sound is not inherently harmful: Dog whistles are designed to emit a sound that is audible to dogs, but not painful. The sound is similar to other high-pitched sounds that dogs encounter in their environment, such as birdsong.
* Training is key: The effectiveness of a dog whistle depends on how it's used. If used properly, it can be a helpful training tool for dogs. However, using it too frequently or harshly can be stressful for the dog.
Important Note: Some dogs may be sensitive to high-pitched sounds and may react negatively to a dog whistle. It's always best to introduce a dog whistle gradually and use it in a positive way, associating it with rewards and positive experiences.
If you're unsure about using a dog whistle with your dog, consult with a veterinarian or certified dog trainer.
