The key to me is whether this birdhouse is bark-activated. If it is, and the high pitched sound only goes off for a short time, then I think this is a good alternative. I think subjecting a dog to a constant high-pitched noise would be mean, as the dog can’t get away from it (and again, none of this is his fault; the poor thing just happens to have a lazy, uneducated and uncaring owner). But I don’t think this is the case here. It does stink that the dog will
never be able to bark, and that is a natural function for dogs, but this is what the players involved are left with when one won’t do the right thing.
An Australian Shepherd is a highly intelligent, very energetic dog bred to
work. It is one of the herding breeds. Obviously the dog is totally frustrated. Working dogs not given a job will make one up themselves. And this dog has done just that. Once he can’t bark anymore, he will find another - digging, fence running, biting, rock chewing, ie whatever he can figure out while left in the yard alone all day. Which sucks for the dog.
Re the previous Psychology Today article that was posted - I think it predicted psychological damage based on being subjected to this hypersonic sound. Not sure I agree with that if the sound is bark-triggered and intermittent. I do agree with most of the rest of the article though, especially about shock collars.
Another, better owner than this one could come along and fairly easily stop this dog’s constant barking. How? By engaging with the dog. It’s really that simple. Owning this type of dog (or any dog) comes with a responsibility of treating it right.
Now, can we talk about constantly clucking chickens and roosters?
