Summary
About Icelandic Sheepdog
The Icelandic Sheepdog is Iceland’s only native spitz‑type herder, medium‑small, sturdy, and agile with a curled tail and thick double coat in varied colors. Cheerful, social, and vocal, it thrives on daily exercise, close family involvement, gentle training, and regular grooming.
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.
