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 Field Spaniel
Medium, athletic gundog with a glossy, feathered coat and dark, expressive eyes. Calm yet enthusiastic, deeply attached to family and often sensitive. Needs kind, consistent training, regular exercise, and mental work. Still relatively rare, valued by dedicated enthusiasts.
