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 Scottish Deerhound
The Scottish Deerhound is a tall, elegant Scottish sighthound with a rough, low‑maintenance coat. Calm and gentle yet athletic, it needs ample daily exercise and secure space. Affectionate, sensitive, and quiet indoors, it suits owners who value a peaceful, devoted large companion.
