I don't have contact info for them currently (or honestly know if they still breed, it's been a few years). Names are Becky Davis (possibly reachable at Specks Pet Supply, Avon, IN 317-272-7738) and Susan Burton.
We have a lab from Dixie Run Labradors in Mauckport. Can't say enough good things about them and our dog Sidley. Larry and Rochelle and family run a nice operation and are really great people. Really good dog with a great disposition. I haven't hunted with Sid and really only worked with him a little but I could tell it wouldn't take him long to train. Larry hunts and does field trials I believe. Check them out either Dixierunlabradors on Facebook or White Lab Puppies & White Lab Breeder in Mauckport IN | Dixie Run Labradors.
I had a dog from Stonelane Hunter Kennels in Evanston, IN. Bertie was great to work with and they appear to have some great bloodline (that is from the little I know about labrador bloodline).
