I had a friend with a dog like that. It would bark at anything. Bug on the sidewalk - bark like crazy. Leaf blowing on the grass - nonstop barking. Snow falling - bark, bark, bark.... I don’t know how they could stand it.
We had a Shetland Sheep Dog. They bark a lot.....at just about anything. My wife used to try to get the dog to stop barking.
I told her that the dog has only one way to communicate audibly, barking and growling. “Do you want to take that away from her?”
The wife relented.
