Dog breeder Aido Vallelado was shocked to see that a hunting dog had given birth to a litter that included two green puppies! The two were the smallest and weakest of the litter. The female puppy died softly after, but the male is hanging on.
Molina, who breeds hunting dogs with her father Manuel Vallelado, 52, in the Spanish town of Laguna de Duero, said her father had called the puppies the Hulk pups, and joked that she should not get them angry.
The male puppy is now gradually beginning to lose his colouring.
Vet Daniel Valverde is now looking into the cause of death of the female puppy and the dogs' colour.
He said: 'There are no other recorded cases of this happening in Spanish scientific literature. I am carrying out virological and bacteriological tests to try and find an answer.'
A similar case in England a couple of years ago was attributed to an exposure to the substance biliverdin in the womb. -via Digg
