Im talking petsmart and a few back yard trainers that teach people to teach their dog how to sit, how to come and how to shake.
any trainer that is worth his salt I cant afford and is also a 3 hour plus drive away. the collar I had was set to vibrate only and was only used when she hackled AND growled. It was never used for shock purposes to correct this behavior (she hates the vibrate cause she is highly ticklish). It was really helping with the e collar on. she wouldn't bark, growl or hackle up but would sit quietly just watching. but take the collar off and she was back to the old behavior.
