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 Welsh Terrier
Medium-sized, sturdy Welsh terrier with a wiry black-and-tan coat that sheds little but needs regular stripping. Bred in Wales to hunt, it is active, bold, affectionate yet independent, with strong chase instincts. Intelligent and trainable, it thrives on firm, positive guidance and daily exercise.
