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 Welsh Terrier
Medium-sized, sturdy Welsh terrier with a wiry black-and-tan coat that sheds little but needs regular stripping. Bred in Wales to hunt, it is active, bold, affectionate yet independent, with strong chase instincts. Intelligent and trainable, it thrives on firm, positive guidance and daily exercise.
