The pit and lab play all the


The pit and lab play all the time.  They’re both still puppies so its always playtime and often they do get a little rough but not aggressive towards each other.  I live way out in the country so obedience classes are pretty much out of the question unless I travel about 4  hours.  These fights have been very serious.  The pit clamps down on the labs nose or ear and won’t let go until he hears us yelling at him.  Then he snaps out of it and instantly feels ashamed only because he knows we’re upset with him.  I’m worried about leaving them alone.  What happens if a fight breaks out and nobody is here to break it up?    

Thanks for your advice Abby.
