there is already exists such device: https://www.aliexpress.com/item/32856921025.html

I didn't tested this one, but at a glance it should works.

But 200 meters is really long distance. There is needs something much more powerful.

You can learn dog to ignore it, the same as you can learn dog to ignore pistol shots near the ear. But most of the dogs will scare it :)

You are maybe right, my four German Shepherds are trained for property and personal protection and they serve for this purpose.
But I never told the training center to teach them for such of things like ignoring this kind of "weapon", but yes, the training center teached the dogs for ignoring weapon shots and reacting if the attacker has a knife or anything in the hand until he/she is attacking etc.
Maybe this is the reason why I never achieved a positive result with such of devices.
Whenever I tried this devices the dogs just listen and was curious what's going on and looked at me like I'm an idiot.  :-DD

most of the aggressive dogs that barking and trying to bite, very scared and cowardly run away when I'm using it. Especially when I use it very close.

On the distance about 1 meter dogs just jumping away like crazy when I power on this device. On the distance about 5 meters they stops to barking and go away with the tail held between the legs. On the distance 10 meters and more they still can hear it but their reaction is not so panic :)

There are possible 2 reason for that:

1) the device has low ultrasonic power level, some models don't works well, also with usual 6f22 battery it works not so good, because a usual battery cannot provide a current of almost 1 Amp, there is needs Li-Ion battery.

2) a deaf dog or when dogs ears are overgrown with hair, so the dog just don't hear it :)

Yellow device works pretty well for most of the dogs. But yes, some dogs just don't hear it for some reason
