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 Mastiff
The Mastiff is a giant, heavily built guardian dog, calm and dignified yet deeply devoted to its family. It is watchful rather than aggressive, needs gentle, consistent training, moderate exercise, and space. Its short coat is easy to maintain, but drool, health care, and costs are significant.
