Summary
About Flat Coated Retriever
Flat Coated Retrievers are medium‑large, athletic gundogs with sleek black or liver coats and friendly, puppy‑like attitudes. Energetic, people‑oriented, and highly trainable, they need plenty of exercise, positive training, close family life, and attentive health care.
About Mastiff
The Mastiff is a giant, heavily built guardian dog, calm and dignified yet deeply devoted to its family. It is watchful rather than aggressive, needs gentle, consistent training, moderate exercise, and space. Its short coat is easy to maintain, but drool, health care, and costs are significant.
