Sorry but I have to come back to this thread...

ACD's are starting to get a bad rap and have been for a few years.
With people like you not putting in the time and effort to train them they are going to end up like pitbulls/shepherds/dobes etc and be put on the dangerous dog list and could eventually be banned from certain places.

They are a breed that needs a special person to train them right and raise them properly.
They aren't your average run of the mill mutt that you can just throw outside (as I remember from lurking your dogs live outside).
These are a working breed, a breed that nips, a breed who can have dominant tendencies, they are a breed that needs to be shown what to do and what isn't acceptable.
You have failed miserably at doing that.

I hope you enjoy ruining the breed.
