GOD'S GRACE

I start Grace on the e-collar early, not sure if it was 5-6 months...Mine has tone, vibrate and shock and all at different levels....I only introduced her to tone as a pup...and it is her signal to return to heel, no matter how fair away she is...(vibrate/shock at a young are confusing to them and may cause misunderstandings.) That's my 2 cents....
