Summary
About Spanish Mastiff
Large, powerful livestock guardian, calm and observant yet strongly protective. Quiet and laid back at home if well exercised, deeply loyal with family and usually reserved with strangers. Independent and thoughtful, it suits experienced owners with space, structure and early socialisation.
About Landseer
The Landseer is a giant, black‑and‑white water rescue and companion dog, calmer and more athletic than a Newfoundland. Gentle, people‑oriented and usually excellent with children, it needs space, regular grooming, steady training, and active owners willing to handle drool, mud and shedding.
