Why does my dog sneeze in my face?

Every day when I get home from work, I get down on the floor to greet our bulldog, and she sneezes directly into my face. I want to be clear that this is not the typical playful half-sneezes that some dogs do, although she does do that with other people. This is an intense, wet, genuine sneeze.

I have tried ignoring her when I get home, thinking that maybe she just needs to calm down a bit, but she will follow me around the house and start whining if I don't acknowledge her. It makes me too sad. I have to give in.

I have a pretty dirty job so I usually hop right in the shower when I get home anyway. A bit of canine spittle really isn't that big of a deal, in the grand scheme of things. I'm really just curious about whats going on. Is she allergic to me?

Thanks
