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 Pyrenean Mastiff
Large Spanish livestock guardian, the Pyrenean Mastiff is a giant, steady dog with a dense white coat and dark patches. Calm, observant and deeply loyal, it’s affectionate with family yet reserved with strangers, needing space, firm but gentle training, and experienced ownership.
