Summary
About Jack Russell Terrier
Jack Russell Terrier: small, sturdy, energetic fox-hunting terrier with bold, intelligent nature. Needs 1–2 hours of daily exercise plus mental work. Predominantly white, three coat types, strong digging and prey drive. Affectionate with family but demanding and unsuited to very sedentary homes.
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.
