CANON CITY, Colorado -- A Colorado dog owner was in for quite a surprise when she helped her Great Dane give birth.
The 8th puppy born to the 3-year-old Great Dane was born green.
Could it have been a case of the luck of the Irish?
Green puppies are a phenomenon that happen when light-colored puppies come into contact with a green pigment found in bile while they are in the womb.
The pigment dyes their fur, but is safe for their health.
All nine puppies were healthy and nursing well.
