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 Collie
The Collie is an intelligent, medium‑large herding dog with a long double coat needing regular grooming. Gentle, loyal, and sensitive, it bonds closely with family and prefers kind training. Adaptable to town or country, it needs daily mental stimulation and exercise to stay content.
