6. Bullmastiff

If you were an expansive estate owner in the Victorian era, you would have definitely known all about this large dog with strong protective tendencies. Because they were developed by gamekeepers who crossed bulldogs with mastiffs to create a pup who can tackle sinister poachers in old England.
