Snoopy and Mo have become friends and daily they have hour+ long wrestling matches. It looks like Snoops is going to bite off Mo's head or maybe MO is going to bite off Snoopy's nose.
Snoopy tries to be very gently with Mo since Snoopy is a bit bigger I think he knows he has to be. Now Mo, fights dirty. He will act like he is tired and will lay down. As soon as Snoopy lets his gaurd down, Mo jumps up ready to attack again. It's great fun watching them.
