I have just started looking for a pup. I'm not too particular but neither do I want just a mutt. I want a hound or a retriever but it doesn't have to be 100% full or registered. Initially I was looking to possibly trade a pistol but soon I'll just sell the pistol and would have up to $500 to spend. I doubt I would spend $500 on a shot in the dark mixed breed though.

What are some sources to look for one other than here and Craigslist?
