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 Karelian Bear Dog
The Karelian Bear Dog is a medium, powerful Nordic spitz bred to track and hold large game. Loyal and often one-person oriented, it is brave, vocal, and naturally watchful. It needs extensive daily exercise, mental work, and consistent, calm training to thrive as an active companion.
