A white mastiff is a rare breed of mastiff that has a white coat. Its formal name is Dogo Argentino, but it is sometimes called an Argentine Mastiff, an Argentino Dogo or just Dogo.
The white mastiff originated in the central region of Argentina. It is a cross of 10 breeds, including an Argentinian breed that is now extinct. The white mastiff was bred to be a working dog and large game hunter, and it has an athletic build and friendly personality.
