Are you sure it's not reverse sneezing? Cooper "reverse-sneezes" out of the blue, usually when he gets excited or he knows something good is about to happen (like treats). He also does it at random times.

That's quaint. :lol:

It still could be reverse sneezing - that doesn't sound anything like sneezing; it sounds more like they're going to throw up a lung when they do it.

He may be having an upset tummy too. I'd see if he's eating grass when he goes outside ... unless he's like Cooper and eats grass anyway.
