Training your dog is no easy feat, but having the best training tools for your small dog will make the process much easier. Small dogs like Beagles and Dachshunds can benefit from a training whistle to let them know that they’ve completed a command correctly. We like the FANZO Dog Whistle, Ultrasonic Dog Training Whistles. The great thing about the FANZO is that it’s adjustable, since different dogs hear and respond to different frequencies. Adjust the whistle to see which setting gets you the best response from your pooch. We also like that your small dog will be able to hear the FANZO whistle at up to 25 feet away when on the proper setting.
