This is Why Your Dog Sneezes When He is Playing Hard

My dog always sneezes on me when I play rough with her and it used to  gross me out a little. I mean, who wants doggy snot all over their hands  and face? But after learning why they do it, I love her even more. 

Why would a dog need to sneeze during a bout of fun and excitement?  According to dog behavior experts, the sneeze is not because of allergies or an itchy nose. It is a signal to other playmates that they're just playing.   The sneeze tells us and other dogs that this is just play and helps keep it from escalating into a real fight. 

  You can also tell that your dog wants to play and not fight if he bows (front end down, rear end up).  It is a friendly gesture that invites another dog - or human - to play.
