HAPPY THANKSGIVING all!,

well here's my problem. I have 2 dogs and have people over today for Thanksgiving. So far only a few people got here but my dogs are INSAINE!? Whenever someone rings the doorbell they both go on their backs and start to pee when the guests come in. They are still little puppies but this is INSAINE! My hardwood floors can't take this!

Help!? is this normal?
