Summary
About Border Collie
The Border Collie is a medium, athletic herding dog known for intense focus, high intelligence and very high energy. Developed to work sheep all day, it excels in herding, sports and training. It needs plenty of exercise, mental stimulation and structured guidance in an active home.
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.
