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 Norwich Terrier
Norwich Terriers are small, sturdy, confident terriers with prick ears, a foxy, alert expression and a harsh, weather‑resistant coat. Bred as farm ratters, they remain lively, curious hunters, need regular exercise, mental stimulation and moderate grooming, and are generally long lived.
