I would just call and make sure it isn't a typo. I bet they meant to put $1800. While it's good to be careful and vigilant...but what ever happened to innocent until proven guilty. Call the number, grill the breeder, ask for more pictures, compare the pic on the website to the ones they send, then make your determination if the ad is bogus or not. If they arent local or within a acceptable driving distance, I wouldn't bother. Unless your friend is dead set on this dog after you've grilled the breeder ask them to meet you at their site/home. If they refuse...hang up the phone. Just my 2 cents
