A green puppy? A green puppy! "The Hulk" was born from a yellow lab in Brazil. I google translated the article for us!:
One of the pups in a litter of Labrador became Mairinque attraction, 65 km from Sao Paulo. A trainer was astonished by the birth of the puppies, who was born with the green. The female Labrador gave birth in the last 30 days, and the dog, nicknamed The Hulk, was the only one whose had the yellow color of the class.
The coat differentiated according vets, it’s rare. This pigmentation occurs by exposure during pregnancy, of a substance called biliverdin, which is part of the placenta. The report has found the TV on Thursday (9) that the cub had lost the green color and the little dog was now with the white coat.
That should clear things up a bit!
