In this video, Buddy does the "Heel" command and stays until released.  When we
take him for a walk on a trail, we will put him in a heel if we come across another
dog or any situation where we want him to stay close by.  He stays in the
command until released with the word "break."
If you can't get the video to load or it "skips", try waiting a couple
minutes and playing it from the beginning again.
