My favorite is not on the list. I am able to admit I'm partial.

Presa Canario 

Caucasian Ovcharka

Dogo Argintino

The Caucasian might be my number one if I wasn't avoiding Ling hair dogs. If I lived in a climate that didn't get so hot and humid I would own them.

The dogo I like too. But my concern was that like many white dog deafness is a common genetic fault.
