My small dog doesn't particularly smell, except for he terribly bad breath. She eats only dry food, but the vet told me that small dogs' saliva is pretty acid, thus their tendency to bad breath...

As many have said, your house, your rules. I'm not at all offended when our lab is not welcome. In fact, I always assume he is not.

But my hosts must also understand that if he doesn't come, we cannot be away for longer than four hours. If they want us for longer, Bruno comes with us, period.
