For the most part the dogs get along great.  In fact they are best friends.  The are bound to be cuddled up next to each other during the colder times of the year, and are always wrestling and playing in the yard and in the house.  However occasionally they cannot get along when there is only one toy for them to share.  This video is of the 2 of them fight over a ball.  It eventually gets to the point where they are so intimidated by each other that they refuse to look each other in the eyes as they growl.  They just keep their eyes on the prize.
