CoCo is a young Aussie/Border Collie who is tied to the front porch 10-16 hrs a day due to the owner's work schedule.  She does come in at night.  But she is very agitated at passing cars and people.

Once she is off her cain, she is sweet and lovable...on the chain she is aggressive and a little frightening.  It is a small yard...please help set 6 posts.
