You're right, Lunas mom, a tool is only a tool. But sincerely, as you say, I prefer trying to understand why the dog behaves in a certain way and then look for the solution than treating the symptom. And that's what electrical collar is needed for: it treats a symptom but does not solve the cause. And it leaves the owner of the pet with a doubt "will my dog behave well or not?".
