A little while ago we had and exercise in LEAVE IT. One of our cats was brave and decided to jump on the back of the couch in the family room where Lani and Toby were. They immediately tried to go after him. I yelled out LEAVE IT and Lani backed off and did not bark, Toby with a little intervention, (a magazine between him and the couch) and repeated leave it did not jump on the couch to get the cat. When Moonee decided not to tempt fate he jumped off the couch to run out Lani started to go after him and I yelled leave it and she turned around and walked away, Toby didn't go after hime either!!!!! I am so proud of them because I know how much fun it would have been for them to terrorize the cat!!!!
