That is a question that use to leave be perplexed but I finally got accurate information. A true Blue Heeler (Australian Cattle Dog) is Blue, White and Brown in color (some may say Black instead of Blue) and they are born with a tail; some tails are cropped after birth.
Now for the a very similar breed of dog that is born without a tail and does not have any brown, only blue and white in color. This my friend is a Stumpy-Tailed Australian Cattle Dog.
Please see the picture of our precious Bear. He was a full-blooded Stumpy-Tailed Australian Cattle. Only Blue and White in color, born with NO tail and although this photo looks like he has green eyes, they were actually a beautiful, very deep brown. A very intelligent, laid-back loving little guy. Unfortunately, we lost him at only 6 months old. He was ran over by our neighbor when he wandered out into the road and we had to have him put to sleep his injuries were so bad. I still won't speak to the neighbor that hit him and then just took off to let him suffer!
