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 Neapolitan Mastiff
Ancient Italian giant guardian with massive build and heavy wrinkles. Calm and affectionate with family, wary of strangers, and protective by nature. Needs early training, steady leadership, moderate daily walks, and careful skin and drool care due to size and loose folds.
