Hybrid Description

The Bull Mastweiler is not a purebred dog. It is a cross between the Bullmastiff and the Rottweiler. The best way to determine the temperment of a mixed breed is to look up all breeds in the cross. It is possible you can get any combination of any of the characteristics found in either breed. Not all of these designer hybrid dogs being bred are 50% purebred to 50% purebred. It is very common for breeders to breed multi-generational crosses. Please review individual breeds for potential health issues.

Bullmastiff Breed Description - Cross #1

The bullmastiff is a large breed of domestic dog. It has a solid build and a short muzzle. The bullmastiff shares the characteristics of Molosser dogs, and was originally developed by 19th-century gamekeepers to guard estates. The breed's bloodlines are drawn from the English Mastiff and Old English Bulldog. It was recognized as a purebred dog by the English Kennel Club in 1924. They are a very quiet dog; they very rarely bark.

It is a brachycephalic dog, flat-faced and short-muzzled, but this does not affect its breathing.

Behavior

Active, agile, showing great endurance and of solid build, the Bullmastiff has a symmetrical appearance. He is earnest, courageous and alert, making him an excellent guard dog. However, he is loyal and gentle, an excellent playmate for children. The Bullmastiff has a very keen sense of smell and a dominant personality. Early, firm, (though gentle) training is required. Bullmastiffs are strong, powerful but sensitive dogs. For a bullmastiff to become a well-behaved family member, consistency is needed. Training and socialization is of high importance. Dogs of this breed are natural guardians of their home and owners. No special guard training is needed for a bullmastiff to react appropriately if his family is endangered. Special approach to bullmastiff training is needed, because these dogs do not like to repeat the same actions again and again. Activities bullmastiffs can really enjoy are obedience, agility, tracking, and carting.

The Bullmastiff is a good house dog if he gets an abundance of exercise. Regular brushing of the coat and cleaning of his folds are required.

Health

Health concerns within the breed include hip and elbow dysplasia, progressive retinal atrophy, bloat, and cancer, with a relatively high incidence of lymphoma and mast cell tumours. Bullmastiffs are prone to certain hereditary diseases, including:

  • Hip dysplasia, affecting 24.5% of individuals
  • Elbow dysplasia, affecting 13.8% of individuals
  • Entropion, hypothyroidism affecting 2.8% of individuals
  • Lymphoma
  • Progressive retinal atrophy is a particular problem, since the trait is an autosomal dominant one. (This has recently been called into question by another medical team and has been proven that some Bullmastiffs have autosomal recessive PRA genes. In America, this is being investigated by the American Bullmastiff Health and Research Committee, and the DNA Optigen test only works for dominant genes, so it is considered inadequate at this time.)


  • Rottweiler Breed Description - Cross #2

    The ideal Rottweiler is a medium large, robust and powerful dog, black with clearly defined rust markings. His compact and substantial build denotes great strength, agility and endurance. Dogs are characteristically more massive throughout with larger frame and heavier bone than bitches. Bitches are distinctly feminine, but without weakness of substance or structure.

    Behavior

    Rottweilers are a powerful breed with well-developed genetic herding and guarding instincts. Potentially dangerous behavior in Rottweilers usually results from irresponsible ownership, abuse, neglect, or lack of socialisation and training. However, the exceptional strength of the Rottweiler is an additional risk factor not to be neglected. It is for this reason that breed experts declare that formal training and extensive socialisation are essential for all Rottweilers. According to the AKC, Rottweilers love their owners and may behave in a clownish manner toward family and friends, but they are also protective of their territory and do not welcome strangers until properly introduced. Obedience training and socialization are required.

    One study published in 2008 found that male Rottweilers have higher confidence, sharpness, and defense and play drives than females.

    A 2008 study surveying breed club members found that while Rottweilers were average in aggressiveness (bites or bite attempts) towards owners and other dogs, it indicated they tend to be more aggressive than average toward strangers. This aggression appears correlated with watchdog and territorial instincts.

    In the Rottweiler Handbook, Joan H. Walker states that "The Rottweiler is very territorial", meaning that the owner will have to regularly work with the dog to control its territorial aggressiveness.

    Generally speaking, Rottweilers are good with children – a combination protector, and playmate. However, as with all dogs, caution must be exercised when infants and children are in their proximity. Infants and children should never be left unattended around any dog, including Rottweilers. Knowing and understanding the temperament of your Rottweiler is your responsibility. Remember that no dog should be brought into your home as a baby sitter. You need to teach the dog to respect your children, and teach your children to respect the dog.

    The dog’s size can be a serious problem. Rottweilers have accidentally caused injuries to small children by bumping into them and knocking them down or into furniture. This bumping is a natural behavior of the Rottweiler, a legacy from the days when the breed was used to herd cattle. Rottweilers will bump and herd children or elderly family members. Some breeders recommend waiting until children are at least school age or older before bringing a Rottweiler into your home. The amount of space in your home, the age of your children, and the amount of time the dog will be in contact with your children should be part of your decision-making process.

    Health

    Rottweilers are a relatively healthy, disease-free breed. As with most large breeds, hip dysplasia can be a problem. For this reason, the various Rottweiler breed clubs have had X-ray testing regimens in place for many years. Osteochondritis dissecans, a condition affecting the shoulder joints, can also be a problem due to the breed's rapid growth rate. A reputable breeder will have the hips and elbows of all breeding stock X-rayed and read by a recognised specialist, and will have the paperwork to prove it.

    They will also have certificates that their breeding animals do not have entropion or ectropion and that they have full and complete dentition with a scissor bite.

    As with any breed, hereditary conditions occur in some lines. The Rottweiler is very prone to osteosarcoma, which is among the most common causes of early death in Rottweilers. For unknown reasons, Rottweilers are more susceptible than other breeds to become infected with parvovirus, a highly contagious and deadly disease of puppies and young dogs.

    If overfed or under-exercised, Rottweilers are prone to obesity. Some of the consequences of obesity can be very serious, including arthritis, breathing difficulties, diabetes, heart failure, reproductive problems, skin disease, reduced resistance to disease and overheating caused by the thick jacket of fat under the skin.

    As with the vast majority of large-breed dogs, Rottweilers are also predisposed to dilated cardiomyopathy.

Based upon this success, Gold came up with the vision for Rescue Me! ― a network which helps all breeds of dogs, cats and other animals find good homes, anywhere in the world. RescueShelter.com is also a free service of Rescue Me! and provides the world's largest and most up-to-date directory of animal rescue organizations for all breeds of dogs, cats and other animals, including a comprehensive directory of wildlife rehabilitators in over 150 countries.
