Summary
About Flat Coated Retriever
Flat Coated Retrievers are medium‑large, athletic gundogs with sleek black or liver coats and friendly, puppy‑like attitudes. Energetic, people‑oriented, and highly trainable, they need plenty of exercise, positive training, close family life, and attentive health care.
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.
