I was backing out of the driveway this morning and heard some yelping like you wouldn't believe. I quickly stop the car and look under the back and there she is, trapped under the muffler crying like mad. I quickly jump back in and pull it forward and she limps outs. We took her to the vet and luckly everything is ok. It's just a sprain in the leg, and she (I) scratched up her foot. :o Good thing she is huge, otherwise I would have just run her over (she stands about 30" and weighs about 130lbs. I'll post a picture later if anyone is interested). If it wasn't cold out, should would have had quite the burn from the muffler.
Hopefully whe will learn her lesson about chassing cars in and out of the driveway (she was actually afraid to walk by my car when we were trying to get her in the truck to go to the vet). Thank god I always go slow through the driveway (maybe my wife will start listening to me about how fast she drives in the driveway).
