Find out what a dog whistle run at, the frequency in cycles per second, I think it should be in the ultrasonic range.
Find an audio tone generator that can reproduce that sound.
See if normal audio speakers can reproduce that sound, if not, then you have to figure out how ultrasonic transducers work.
At that high a frequency, I don't think there are perceivable musical qualities of pitch and tone. That may be the reason you only find circuits specifically to output a dog whistle, unless you want to talk to the animals. Good luck.

it doesn't exactly have to be as high as a dog whistle but i do need something that can at least generate high tones everything i see on here so far only emits things in song or patterns
