They are a very interesting, & lovely breed too own. Also almost extinct.
I'm working on keeping, & preserve the Indian Malays, which are the originals before being bred to the SOP.
Indio Gigantes do vary in appearance. So he maybe. But he could also be an Oriental Cross.
Another possibility is he's just a Malay with high set tail, which is seen from time to time, but isn't exactly desired.
