Dog Whistle App
The whistle was invented by Francis Galton who was also the half cousin of Charles Darwin, the very same person who discovered the theory of evolution. The dog whistle ordinarily referred to as a silent whistle or Galton whistle, is a type of whistle that is utilized when training dogs or cats for particular purposes. Why this instrument works so well it is because a dog's hearing is so much out of range compared to that of a human.
Dogs can hear sounds at a much lower frequency compared to what humans can. Some dog whistles even have sliders so that you can use it to adjust the sound frequency.
Many dog owners utilize the dog whistle to help train or condition their dog. No matter of how good of an individual dog trainer is, using a dog whistle will nearly always make the job a whole lot easier to do. For instance, they may use the dog whistle to help get their dog's attention when they are trying to get in contact with them from a distance. Or, they can use the dog whistle to help condition the dog.
