Summary
About Australian Shepherd
The Australian Shepherd is a medium, athletic herding dog, highly intelligent and energetic. Loyal and people oriented, it bonds closely and needs substantial daily exercise, training, and mental work. Its striking, weather resistant coat and varied eye colors add to its appeal.
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.
