That's so sad that they sell DOGS on ebay... how horrible!
When ebay finds out, they will cancel that auction, and probably terminate that person's account. If you ever see anything questionable or illegal on ebay, just email them about it. They are very strict, and very good about taking things off like that.

I have been buying and selling hundreds of things on ebay for years. I've never had a problem. Feedback is very, very useful thing, don't forget to check it before bidding.

And, sometimes it takes a LONG time for things to get across the border, especially with heightened post-9/11 security. It could takes weeks and weeks. Just keep in touch with the seller.
