Keighan is a AKC registered red merle with one blue eye. He has sired two litters and in both there were more merles than tris. He is a wonderful boy, very mellow and laid back. So far he has passed along his very calm demeanor to all of his pups. We had him tested for hereditary cataracts HSF4 and he tested n/n. I have not done the OFA test, but its because I dont believe it has anything to do with how the pups will turn out. If you breed 2 dogs that both have a OFA rating of Good or Excellent, it does not mean that they will produce pups with good hips it just means that the parents have good hips. Keighan comes from CH bloodlines. You can see a copy of his pedigree on my website at www.silverbrookaussies.com as well as some of his past pups. If you have any questions please feel free to call me. Thanks, Amee Silverbrook Aussies
