To want my relatives to visit without bringing their dog?

[Lindy2]

I like dogs but I've never owned one so I really don't know if I'm being unreasonable here or not.
We have family members who have a pet dog. She's quite friendly but very excitable and energetic and runs around and jumps a lot. We tend to see each other at Christmas but we mostly go to them as if we invite them to visit us they always want to bring the dog along.
I find it a bit strange that the dog is expected to visit too and actually I don't really want their dog running around our home.

We have other pets that don't get on well with dogs and would get stressed by it being here. We also have wooden flooring and don't really want it scratched to bits by the dog. Their own wooden floor has been completely wrecked by the dogs claws. I also find the combination of excited dog and excited children a bit full on and handle it much better if it's not taking place in my home.
I get the feeling that they think I'm a bit mean saying that we don't really want the dog here. Is it usual though for dog owners to take their dog everywhere with them? I find it a bit odd. They live about 1 hour away so don't stay over night.
We've invited them to ours this year and the dog issue has come up again of course.
What do mumsnet dog owners think? Am I a dog hating misery or are they a bit dog obsessed?

Hopefully they aren't being passive aggressive with the 'well, we can't stay as long then'? It would be unreasonable to make you feel guilty about not wanting the dog. But it's not unreasonable for them to make the visit shorter to avoid leaving her alone. Dogs really shouldn't be alone for more than a few hours.

Most of my friends bring their dogs when they visit, or I do when I go to theirs, but that's because we're all mad dog people (showing, obedience, agility, breeding, etc). If I were going to someone who wasn't part of our little group of dog show people, then the dogs stay home, unless specifically invited.
