I'm really sorry this happened to you. I just can't seem to wrap my mind around why someone would want to do this. There are so many other breeders and beautiful puppies for sale... why rush into purchasing one you know someone else has their eye on. Even on that site, there were several other puppies with adorable faces. Not to mention, it'd be kind of hard to part with 3000 for a puppy when I know there are so many others that are cuties too, but much less expensive. It is just very strange to me.
I do hope you end up finding a good breeder, a fair price, and last but not least a beautiful new puppy that you'll just know is the perfect fit for you
