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 Irish Terrier
Medium, athletic terrier with a wiry red coat, low shedding when properly groomed. Intelligent, energetic, and independent, needing daily exercise and mental stimulation. Deeply loyal and people‑oriented, a keen watchdog, with strong prey drive and sometimes challenging with other dogs.
