Summary
About Pyrenean Mastiff
Large Spanish livestock guardian, the Pyrenean Mastiff is a giant, steady dog with a dense white coat and dark patches. Calm, observant and deeply loyal, it’s affectionate with family yet reserved with strangers, needing space, firm but gentle training, and experienced ownership.
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.
