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 Neapolitan Mastiff
Ancient Italian giant guardian with massive build and heavy wrinkles. Calm and affectionate with family, wary of strangers, and protective by nature. Needs early training, steady leadership, moderate daily walks, and careful skin and drool care due to size and loose folds.
