Electric anti-bark collars
Excessive barking can be a nuisance, especially when the neighbors start complaining, but Wirant cautions against using an electric collar to curb the behavior.
While the collars can be effective, dogs may start to associate the unpleasant electric shock with objects or behaviors other than barking.
For example, if your dog always barks at your neighbor, he may learn to associate the shock with the neighbor instead of his barking. In this case, other unwelcome behaviors, such as running from the neighbor or becoming aggressive toward him, could arise.
Instead of the collar, Wirant suggests working with a qualified trainer to determine what’s causing your dog to bark and how to manage the behavior in a more humane way.
