Summary
About Australian Terrier
The Australian Terrier is a small, sturdy working terrier with a harsh, weatherproof coat and soft topknot. Bred in Australia as a vermin controller and companion, it is confident, lively, people‑oriented, a devoted watchdog, needing moderate exercise and regular, simple grooming.
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.
