This topic came up between a friend of mine and me -- I am on a waitlist for a litter that has just arrived, and my breeder asked for references. My friend, who is listed as a reference, got a poodle last spring from a different breeder who did NOT require references, and told me she thinks it's nuts that breeders would require references. I said I thought it was fairly common. So here's my attempt to determine just how common it is. What has been your experience with providing references (or requiring references, if you are a breeder)?
