Colorado dog owner helps Great Dane birth rare green puppy

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.
