Nestlé Purina PetCare in Germany created a commercial especially to attract a dog’s attention by inserting high pitched sounds in the ad which only a dog can hear.  The squeaky noises are hoped to attract the dog’s attention and the dog will attract their owner’s attention. link

I played the video on my computer (which is to the camera’s right) for Floss.  This is an unscientific (i.e. only useful to be cute and show off my dog) test.

As you can see, Floss noticed the sound but wasn’t attracted to it.
