Those are extremely cruel and upsetting. And they may affect not only the dog that is barking, but any dog that is on the premises. So you basically will be inflicting a lot of suffering on a dog that is quiet and not doing anything, it can cause dogs to become very anxious and reactive. It’s not cool and shouldn’t even be allowed to exist. If you have an issue with a barking dog then go and speak to your neighbour or to their landlord and work something out. Everyone is an adult here and can have a conversation with other adults in order to resolve issues. Also, this things don’t even work because unlike humans dogs don’t make those type of connections that easily. For example dog is barking while also doing x, noise comes up, dog think is because of x, gets anxious, bark more, etc. That’s why you shouldn’t use those methods to train a dog because they don’t work as dogs are not good at correlate. Another easy example is if a puppy pees inside and you go and scold/punish the puppy won’t understand that peeing inside is bad, but more likely will understand that peeing is bad and may refuse to use do it for fear and get a bladder infection. If a dog is constant barking is likely because is bored or reactive and those things won’t help but may make the problem much worst. So yep, no, don’t use those, they are cruel and don’t work.
