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 American Staffordshire Terrier
American Staffordshire Terrier: muscular, medium-sized, people-focused dog with a short, easy-care coat in many colors. Affectionate, energetic, and highly trainable with consistent, positive handling. Needs daily exercise, mental stimulation, socialization, and responsible management.
