There's more than one way to train a dog.
I certainly agree with you on that one! Apparently you found my post offensive and, for that, I apologize. Yesterday, you were still asking for ways to fix the problem (well, actually, you still are today) and so I answered you to the best of my ability.
Extreme to me is using one of those barking collars...
Agreed! A penny can is also less aversive than being sprayed with water or being shaken.
This is how you characterized the penny can when you starting using it:
So I then proceed to say "quiet" and then rattle an empty soda can full of pennies every time she barks. I think it scared the heck outta her! I felt really mean, scaring my baby like that...
You asked for alternatives and that's what I gave you. I'm sorry that my answering your question offended you.
