Summary
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.
About Tosa
The Tosa is a large, powerful Japanese breed, calm and dignified at home yet naturally protective. Loyal and often devoted to one person, it needs experienced handling, early socialisation and consistent training. Short-coated but high-commitment, it faces legal restrictions in some countries.
