I'm for betterment of the breed. Have raised springers all my life. The AKC has different documents on their site. check there. Also make sure both dogs are reg. If not then I don't think it's a good idea.
Now no one get mad, I have had tons of mutts but I'm a firm beleiver in being able to judge a dogs possible demenor by it's breed. I know most non pure breeds are nice but as someone who has rescued "nice pups who became mean " I know the results of those animals. I also know each animal and it's envoirment plays a part in it's life. but pure breeds give a very good start to decide on what fits your family.
