Summary
About Chihuahua
The Chihuahua is a tiny yet sturdy companion dog, usually 1.5–3 kg with an apple-shaped head and large eyes. Found in smooth or long coats in many colors, it is devoted, alert, and bold. It needs daily walks, training, close companionship, and good health and dental care to thrive.
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.
