YouTube - Dog Training - How to choose dog obedience classes. Part 5
In this video the dog trainer says that if you use punishment eg if the dog growls at another dog and u punish the dog by giving him a check on the check-chain he suppresses the behaviour and associates pain with seeing another dog so he stops growling and goes into attack mode.
So my question is: How do i get my dog to not growl at another dog and it being safe rather then checking him and him supressing the growl and turning it into a bite. how do i punish the behaviour without damaging what is still needed
