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 Smooth Fox Terrier
The Smooth Fox Terrier is a small, athletic, people‑oriented terrier with a short, easy‑care coat. Energetic, intelligent and independent, it needs plenty of exercise, training and mental stimulation. Affectionate yet intense, especially with small animals, it suits active, consistent owners.
