Well I only found this on the AKC website:
But this person should be able to get you in touch with Dal breeders on the west coast. You can also check the breeder listings in Dog Fancy or other monthlies...it's not guaranteed that thesde will necessarily be GOOD breeders, but once you strt networking, you should be able to get referals.
Good luck! I have a friend with a Dal mix - all I know is they are high energy dogs who shed a lot, but they are sweet as heck usually.
