I just wanted to point out that many dogs from shelters are purebred and when people talk about shelters and rescues that includes breed-specific rescues too. My golden retriever is a rescue. Just for clarification. Blowing up at people really doesn't do any good, it just gets yourself so upset that you can't see any sense in what some people may be saying, you shut yourself off to learning or considering different viewpoints. With that said, I wish you the best.

edit: I was posting the same time as Kay was.
