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 Cocker Spaniel
Cheerful, medium‑sized gundog with a sturdy build, soft expression, and long silky ears. Bred to hunt woodcock, it loves sniffing, searching, and joining family activities. Sensitive and people‑oriented, it needs daily exercise, mental stimulation, and regular grooming to stay healthy and content.
