Given the proper care and training, these puppies, known commonly as English Mastweilers (or just Mastweilers), grow into big dogs with big hearts that combine their forebears’ best traits physically and temperamentally.
Physical Traits of a Typical Rottweiler Cross Bullmastiff
Although the prevalence of the characteristics can always vary due to the balance of Rottweiler and Bullmastiff in the individual dog’s lineage, certain traits are going to be evident in most Mastweilers.
For one thing, these dogs are tremendous in size. Female adults average around 110 pounds, and males average 130 pounds. Their heads are huge, squarish, and rock-solid, and their bite is evenly set.
An average Mastweiler has a body structure that strikes a delicate balance between the powerfully agile Rottweiler and the bulky Bullmastiff.
These dogs will often have a solid body with powerful leg muscles and a chest that is somewhat broad, but less prominent than that of a purebred Bullmastiff. Their coats include a large variety of colors encompassing both of their original breeds.
Temperament and Intellect of a Bullmastiff and Rottweiler Mix
When socialized correctly by caring owners, a Mastiff Rottweiler mix will defy any aggressive reputation of its parent breeds, growing up into a gentle giant with a mellow, friendly personality that can double as an effective guard dog based on its size alone.
These dogs are generally wonderful with children, though they aren’t always aware of their own strength, so supervision around small kids is highly advisable.
English Mastweilers are the product of two very intelligent breeds, albeit ones that respond to instruction in different ways. They respond well to positive reinforcement in training, though the relaxed Mastiff side of the dog’s personality will likely make training slow.
Mastweilers love to make use of their powerful limbs for jumping, and some can easily clamber over surfaces up to six feet high. If this is a problem for you as an owner, either give it a special focus in your training or try to make your surfaces climb-proof.
Health and Issues Facing Mastweilers
Mastweilers have a significantly longer average lifespan than purebred Bullmastiffs, ranging between nine and thirteen years of age. As with most large dogs, they can become victims of bloat, especially at an older age. Hip dysplasia can be a concern, and if it is detected, it needs to be treated as early as possible.
Bullmastiffs can suffer from a form of progressive retinal atrophy (PRA) that is inherited through dominant genes, thus making them an especially susceptible breed. Owners of Mastweilers should be aware of this condition so that, if their dog turns out to be affected, measures can be taken to delay the onset of blindness.
Bringing a healthy and happy member of a litter of Rottweiler Bullmastiff mix puppies into your home can be a highly rewarding decision, giving you and your family a companion, protector, and buddy for the next decade to come.
