Summary
About Irish Terrier
Medium, athletic terrier with a wiry red coat, low shedding when properly groomed. Intelligent, energetic, and independent, needing daily exercise and mental stimulation. Deeply loyal and people‑oriented, a keen watchdog, with strong prey drive and sometimes challenging with other dogs.
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.
