What every dog owner should know about shock/prong collars

As a training coach for reactive dogs, I meet guardians who feel frustrated and overwhelmed. They love their dogs but struggle with pulling, barking at strangers, or lunging at other dogs. Looking for answers, some turn to shock collars or prong collars.
At first, these tools can appear to work. The pulling stops and the lunging decreases. But what often looks like improvement is actually suppression. The behaviour may disappear on the outside while the dog’s fear, anxiety or stress remain
