Summary
About Bouvier des Flandres
Powerful, rugged herding dog from Flanders, medium‑large with a thick, tousled double coat and bearded face. Calm yet serious, strongly loyal and protective, it needs early socialization, confident positive training, regular mental challenges, and plenty of daily exercise.
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.
