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 Brittany (Breton)
The Brittany (Épagneul Breton) is a compact, athletic French gundog with a short or bobbed tail and easy‑care coat.
