Summary
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.
About Rottweiler
The Rottweiler is a strong, medium‑large working dog with a short black coat and rust markings. Calm, loyal, and family‑oriented, it tends to be reserved with strangers. It needs kind, consistent training, daily mental and physical exercise, and responsible ownership to thrive.
