Introduction
A hybrid breed that results from crossing a Bernese Mountain Dog with a good old fashioned Mastiff, Mountain Mastiffs are big dogs with equally big hearts who are very protective of the members of their households - be they human or animal. Due to being hybrid dogs, Mountain Mastiffs tend to look drastically different from one another; a Mountain Mastiff who's retained more traits from their Bernese parent may have a thicker coat than a Mountain Mastiff that favors their Mastiff parents more. No matter which parent they favor, one should expect a Mountain Mastiff to grow to a large size, have a strong build, and have a preference for engaging in physical activities more than brain teasers and the like.
Conclusion
Once properly trained, a Mountain Mastiff can make for a great family pet as well as an excellent guard dog due to their reserved personality and poised demeanor. Mountain Mastiffs are very trainable dogs, which makes it easy to teach them new skills and concepts over a relatively short period of time. Being the large dogs that they are, Mountain Mastiffs tend not to do too well in small spaces so you may not want to adopt one of these dogs if you live in an apartment complex or a particularly small house. Overall, however, Mountain Mastiffs are very self-sufficient and hardy breeds who aren't needy by any stretch of the imagination.
