The Presa Canario is a massive, muscular dog originally bred for guarding livestock in the Canary Islands. They are known for being highly dominant and fearless, making them dangerous in the wrong hands.
Due to multiple high-profile attacks, Presa Canarios have been banned in Australia and New Zealand, and ownership is restricted in several European countries. Their protective instincts and territorial nature require strong, experienced owners who can establish firm boundaries.
Why They’re Banned: Guarding instincts, dominance, and past attacks. Where They’re Banned: Australia, New Zealand, and parts of Europe.
