You’d think someone comparing a Biewer Terrier and a Mastiff is just browsing at opposite ends of the dog spectrum, but it happens. Usually it’s a couple debating their next dog after losing a longtime pet, or a family rethinking their lifestyle, torn between cozy companionship and that noble, protective presence.
