B4Boy,
i would be taking your complaint to the manager of the pound, because what they have done and said is BS.
the people working there are usually volunteers, so maybe the person you were dealing with just had a bad day or something.
you sound like a person with a genuine interest for owning a dog, and have done the right thing by going to the pound.
good luck with it mate, let us know how it goes
cheers, Steve
