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 Weimaraner
Large, athletic German gundog with a sleek silver-grey coat and amber eyes. Energetic, intelligent and strongly people-oriented “Velcro dog” needing 1.5–2 hours of daily exercise plus training. Versatile in dog sports; without stimulation may become noisy, destructive or escape-prone.
