Summary
About Greyhound
Tall, slender Greyhounds are sprinting sighthounds, built for speed yet calm indoors. They have a short, low‑maintenance coat in many colors and need soft bedding and weather protection. Gentle, sensitive, and affectionate, they suit owners who provide routine, kind training, and moderate daily exercise.
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.
