Summary
About American Cocker Spaniel
American Cocker Spaniel: a small, sturdy gundog with a silky coat and large, expressive eyes. Cheerful, affectionate, and people‑oriented, it suits active families. Needs daily exercise, mental stimulation, gentle positive training, and regular, thorough grooming and ear care.
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.
