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 Irish Water Spaniel
Medium–large, athletic gundog with a distinctive curly liver coat, smooth face and tapering “rat tail.” Clever, water‑loving retriever that forms close bonds, often to one person. Needs substantial daily exercise, mental work, regular grooming and kind, consistent training.
