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 Weimaraner
Large, athletic German gundog with a sleek silver-grey coat and amber eyes. Energetic, intelligent and strongly people-oriented “Velcro dog” needing 1.5–2 hours of daily exercise plus training. Versatile in dog sports; without stimulation may become noisy, destructive or escape-prone.
