Summary
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.
About Brittany (Breton)
The Brittany (Épagneul Breton) is a compact, athletic French gundog with a short or bobbed tail and easy‑care coat. Affectionate, sensitive, and highly energetic, it needs substantial daily exercise and gentle, positive training, thriving as both an active family companion and versatile hunting dog.
