It is nicknamed as Canary Mastiff. It once served as a guard dog for livestock on the Canary Islands. Its bite force is 540 PSI. It is strong enough to rival a jaguar!
This dog has an alpha mentality, which makes it exert dominance over other pets and strangers. However, these dogs can be loyal and protective if provided the right training. But they were originally bred to be used as fighting dogs.
