Do you mean the "sorta sneeze" they do? I think mine do that when they think/want that we are going on a walk or into the garden to run about. It's a signal of "let's go adventuring".

There's also the high pitched excited yip and then the tongue out wiggling walk thing as well both of which might be laughter I think.

I read about the “sorta sneeze” as being a call for consensus for “let’s go”. When my dog did that as we were getting ready to go out, I tried making a similar sound back and the dog looked at me immediately like I finally said something she understood!
