Summary
About Australian Kelpie
The Australian Kelpie is a medium, athletic herding dog, bred for stamina and focus. Intelligent and quick to learn, it needs extensive daily exercise and mental work. Affectionate yet independent, it excels in herding and dog sports, stays generally healthy, and suits active, committed homes.
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.
