6 Of The Most Popular Mastiff Mix Breeds?

Mastiff-type breeds have a rich history as the first domesticated dogs known to aid humans from one empire to the next. This allowed us to know that the strength, intelligence, and trainability of Mastiffs are not just specific to the ones we own, but are present in most Mastiff breeds all over the world. Because Mastiffs have been historically used as guard dogs, their owners today rely on this great skill of theirs. Their loyalty and instinct to protect and defend their owners make them desirable for many. Their characteristics however, do not exempt them from complications arising from interbreeding. Because of their huge size, purebred Mastiffs are known to experience joint pain from carrying their weight, stomach illnesses that result from their deep chests, and heart diseases. The avoidance of these possible illnesses, along with people’s desire for variety, increased the popularity of breeding Mastiffs with other breeds features and traits that are as desirable.
