Summary
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.
About Irish Wolfhound
Irish Wolfhounds are giant, tall hounds with a strong yet graceful build and a rough, weather‑resistant coat. Calm, gentle and sensitive, they are low‑key indoors but need steady exercise and space. They have notable health risks and a relatively short lifespan, so careful breeding and care are vital.
