Summary
About Bullmastiff
Large, powerful guardian originally bred to catch poachers, the Bullmastiff is calm, confident and deeply loyal, often bonding closely with one person. It has a short, low‑maintenance coat, needs space, consistent early training and socialisation to guide its natural protectiveness.
About Shiba Inu
Ancient Japanese spitz-type hunting dog, small yet muscular with foxlike face, curled tail and plush double coat in red, black and tan or sesame with urajiro. Independent, catlike, loyal but reserved, strong-willed, high prey drive, needs early socialisation, firm positive training and regular exercise.
