Summary
About Chesapeake Bay Retriever
The Chesapeake Bay Retriever is a strong American waterfowl retriever with a muscular build and oily, wavy brown double coat for cold waters. Loyal and reserved, it bonds closely with family, needs firm, fair training, and high daily exercise, and is generally robust but prone to joint and eye issues.
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.
