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 Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
