You're well within your rights to say "No Dog". It's your house, and visitors shouldn't bring pets.

My wife's sister and bro-in-law won't come to visit us, since we said that they couldn't bring their miserable miniature dachshund, as we have cats. Every time I see the yappy thing, I find myself pondering "drop kick or punt"?

We don't bring our cats when we visit them, so it's only fair.
