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 Miniature Schnauzer
Compact, sturdy Miniature Schnauzers are bright, trainable, and people focused. Their wiry, low shedding coat needs regular grooming. Alert watchdogs with a terrier streak, they need daily exercise, mental stimulation, and clear training, and often live 12–15 years.
