I have a male Austrailian Cattle Dog - Blue Heeler Puppy that was born on Thursday February 11, 2010. The father is a registered blue and the mother is a purebred blue that does not have the red/brown/tan on her anywhere. The puppies will look just like their mom - no red/brown/tan on them anywhere. They are excellent workers/pets. The dew claws have been removed but the tail has not been docked. They will be ready the last of March.
