Your dog is special! She’s your best friend, companion, and a source of unconditional love. Chances are that you chose her because you like Bullys and you expected her to have certain traits that would fit your lifestyle:

Formidable guard dog; highly territorial
Even-tempered; adapts to a wide variety of environments
Quiet—not much of a barker
Intelligent and reliable
Confident, steady, and fearless
Has a short, easy-to-care-for coat
However, no dog is perfect! You may have also noticed these characteristics:

Early obedience training and socialization is recommended
Suspicious of strangers
Needs frequent attention from her family
Prone to boredom and separation anxiety when left alone and will find trouble
Overprotective of family and territory if not socialized properly
Not easily trained
Is it all worth it? Of course! She’s full of personality, and you love her for it! The Bullmastiff is a gentle giant. She is self-assured, docile, and loves children. She is naturally protective of her family and has moderate exercise needs. She’s lovely to cozy up with, but she is known to drool and snore.

The Bullmastiff was developed in England from 60% Mastiff and 40% Bulldog to create a fast and reliable guardian of estates. They were known as the “Gamekeeper’s Night Dog,” because they were able to run down a poacher and hold them until the watchmen could arrive! Bullys are highly territorial, may not accept other dogs in their area, and can have an intense prey drive. The Bullmastiff is a giant breed with an average lifespan of 9-10 years, known to suffer from some common conditions like hip or elbow dysplasia, bloat, and cancer.

Your Bullmastiff’s Health

We know that because you care so much about your dog, you want to take good care of her. That is why we have summarized the health concerns we will be discussing with you over the life of your Bullmastiff. By knowing about health concerns specific to Bullmastiffs, we can tailor a preventive health plan to watch for and hopefully prevent some predictable risks.

Many diseases and health conditions are genetic, meaning they are related to your pet’s breed. There is a general consensus among canine genetic researchers and veterinary practitioners that the conditions we’ve described herein have a significant rate of incidence and/or impact in this breed. That does not mean your dog will have these problems; it just means that she is more at risk than other dogs. We will describe the most common issues seen in Bullmastiffs to give you an idea of what may come up in her future. Of course, we can’t cover every possibility here, so always check with us if you notice any unusual signs or symptoms.

This guide contains general health information important to all canines as well as the most important genetic predispositions for Bullmastiffs. This information helps you and us together plan for your pet’s unique medical needs. At the end of the booklet, we have also included a description of what you can do at home to keep your Bully looking and feeling her best. You will know what to watch for, and we will all feel better knowing that we’re taking the best possible care of your pal.
General Health Information for your Bullmastiff

Dental Disease

Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. And unfortunately, your Bullmastiff is more likely than other dogs to have problems with her teeth. It starts with tartar build-up on the teeth and progresses to infection of the gums and roots of the teeth. If we don’t prevent or treat dental disease, your buddy will lose her teeth and be in danger of damaging her kidneys, liver, heart, and joints. In fact, your Bullmastiff’s life span may be cut short by one to three years! We’ll clean your dog’s teeth regularly and let you know what you can do at home to keep those pearly whites clean.

Infections

Bullmastiffs are susceptible to bacterial and viral infections — the same ones that all dogs can get — such as parvo, rabies, and distemper. Many of these infections are preventable through vaccination, which we will recommend based on the diseases we see in our area, her age, and other factors.

Obesity

Obesity can be a significant health problem in Bullmastiffs. It is a serious disease that may cause or worsen joint problems, metabolic and digestive disorders, back pain and heart disease. Though it’s tempting to give your pal food when she looks at you with those soulful eyes, you can “love her to death” with leftover people food and doggie treats. Instead, give her a hug, brush her fur or teeth, play a game with her, or perhaps take her for a walk. She’ll feel better, and so will you!
Parasites

All kinds of worms and bugs can invade your Bully’s body, inside and out. Everything from fleas and ticks to ear mites can infest her skin and ears. Hookworms, roundworms, heartworms, and whipworms can get into her system in a number of ways: drinking unclean water, walking on contaminated soil, or being bitten by an infected mosquito. Some of these parasites can be transmitted to you or a family member and are a serious concern for everyone. For your canine friend, these parasites can cause pain, discomfort, and even death, so it’s important that we test for them on a regular basis. We’ll also recommend preventive medication as necessary to keep her healthy.

Spay or Neuter

One of the best things you can do for your Bullmastiff is to have her spayed (neutered for males). In females, this means we surgically remove the ovaries and usually the uterus, and in males, it means we surgically remove the testicles. Spaying or neutering decreases the likelihood of certain types of cancers and eliminates the possibility of your pet becoming pregnant or fathering unwanted puppies. Performing this surgery also gives us a chance, while your pet is under anesthesia, to identify and address some of the diseases your dog is likely to develop. For example, if your pet needs hip X-rays or a puppy tooth extracted, this would be a good time. This is convenient for you and easy for your friend. Routine blood testing prior to surgery also helps us to identify and take precautions for common problems that increase anesthetic or surgical risk. Don’t worry; we’ll discuss the specific problems we will be looking for when the time arrives.

Genetic Predispositions for Bullmastiffs
Bloat

Gastric Dilatation and Volvulus, also known as GDV or Bloat, usually occurs in dogs with deep, narrow chests. This means your Bullmastiff is more at risk than other breeds. When a dog bloats, the stomach twists on itself and fills with gas. The twisting cuts off blood supply to the stomach, and sometimes the spleen. Left untreated, the disease is quickly fatal, sometimes in as little as 30 minutes. Your dog may retch or heave (but little or nothing comes out), act restless, have an enlarged abdomen, or lie in a prayer position (front feet down, rear end up). Preventive surgery in which the stomach is tacked down or sutured in place so that it is unlikely to twist is an option. If you see symptoms, take your pet to an emergency hospital immediately!

Bone and Joint Problems

A number of different musculoskeletal problems have been reported in Bullmastiffs. While it may seem overwhelming, each condition can be diagnosed and treated to prevent undue pain and suffering. With diligent observation at home and knowledge about the diseases that may affect your friend’s bones, joints, or muscles you will be able to take great care of him throughout his life.

Growing Bullmastiffs can suffer from a painful inflammation of the long bones in the legs, a condition called eosinophilic panosteitis, pano or eo-pan. It usually starts at around six to ten months of age and shifts from leg to leg. We’ll look for this condition upon examination; if your pal exhibits pain when the area is squeezed or palpated, we’ll take X-rays to diagnose the problem. Panosteitis usually causes no permanent damage, but requires pain medication. If your dog has the condition and has developed an abnormal gait to compensate for the sore leg(s), rehabilitation exercises may be required.

When Bullmastiff puppies are allowed to grow too quickly, the cartilage in their joints may not attach to the bone properly. This problem is known as osteochondritis dissecans or OCD. If this occurs, surgery may be required to fix the problem. It’s best to stick to our recommended growth rate of no more than four pounds per week. Don’t overfeed him and don’t supplement with additional calcium. Feed a large-breed puppy diet rather than an adult or a regular puppy diet. Weigh your puppy every three to four weeks.

Both hips and elbows are at risk for dysplasia, an inherited disease that causes the joints to develop improperly and results in arthritis. Stiffness in your Bullmastiff’s elbows or hips may become a problem for him, especially as he matures. You may notice that he begins to show lameness in his legs or has difficulty getting up from lying down. We can treat the arthritis—the sooner the better—to minimize discomfort and pain. We’ll take X-rays of your dog’s bones to identify issues as early as possible. Surgery is sometimes a good option in severe and life-limiting cases. Keep in mind that overweight dogs may develop arthritis years earlier than those of normal weight, causing undue pain and suffering!

Cancer

Cancer is a leading cause of death among dogs in their golden years. Your Bullmastiff is a bit more prone to certain kinds of cancer starting at a younger age. Many cancers are cured by surgically removing them, and some types are treatable with chemotherapy. Early detection is critical! We’ll do periodic blood tests and look for lumps and bumps at each exam.
Knee Ligament Tear

The cranial cruciate ligament is one of the four tough bands of tissue that hold each knee together. A torn cranial cruciate ligament is a common injury in active dogs, which includes your Bully. Usually surgical correction is done to stabilize the knee and help prevent crippling arthritis. Physical therapy and multimodal pain management are necessary to get the best outcome. Keeping him at the right weight, feeding a high-quality diet, and avoiding too much twisting of the knees (like playing Frisbee) are key in avoiding this painful injury.

Neurological Disease

A genetically linked neurological condition that could occur in your Bullmastiff causes a wobbly, drunken gait. This condition, known as wobbler disease or wobbler syndrome, happens because there is a narrowing of the vertebrae in the neck, which pinches the spinal cord and associated nerves. If the nerves do not send signals to the brain the way they are supposed to, your dog cannot feel his feet. The first signs you will often notice are unstable hind legs, stumbling, and sometimes falling. Medications, neck braces, rehabilitation exercise programs, and surgery are treatment options.

Eye Problems

Not many things have as dramatic an impact on your dog’s quality of life as the proper functioning of his eyes. Unfortunately, Bullmastiffs can inherit or develop a number of different eye conditions, some of which may cause blindness if not treated right away, and most of which can be extremely painful! We will evaluate his eyes at every examination to look for any signs of concern.
Heart Disease

Bullmastiffs are especially prone to a life-threatening heart condition known as dilated cardiomyopathy, or DCM , in which the heart becomes so large, thin, and weak that it can no longer effectively pump blood to the body. As this problem advances, he may act weak or tired, faint or collapse, breathe in a labored way, or cough. We’ll conduct a yearly electrical heart screening(ECG) and/or an echocardiogram starting at age one to look for abnormal heart rhythms early. If found, we’ll treat this condition with medication and may also recommend dietary supplementation.

Bladder or Kidney Stones

There are a few different types of stones that can form in the kidney or in the bladder, and Bullmastiffs are more likely to develop them than other breeds. We’ll periodically test his urine for telltale signs indicating the presence of kidney and bladder stones; they are painful! If your buddy has blood in his urine, can’t urinate, or is straining to urinate, it is a medical emergency. Call us immediately!

Reproductive Difficulties

Breeds with a large head and small pelvis are more prone to difficulties during the birthing process. Her pelvis is just too small to pass puppies and a C-section is often required for her health and that of her puppies. If you are interested in breeding your Bully, speak with us first. We can help you make an informed decision based on body conformation of both sire and dam.

Allergies

In humans, an allergy to pollen, mold, or dust makes people sneeze and their eyes itch. In dogs, rather than sneeze, allergies make their skin itchy. We call this skin allergy “atopy”, and Bullmastiffs often have it. Commonly, the feet, belly, folds of the skin, and ears are most affected. Symptoms typically start between the ages of one and three and can get worse every year. Licking the paws, rubbing the face, and frequent ear infections are the most common signs. The good news is that there are many treatment options available for this condition.
Taking Care of Your Bullmastiff at Home

Much of what you can do to keep your dog happy and healthy is common sense, just like it is for people. Watch her diet, make sure she gets plenty of exercise, regularly brush her teeth and coat, and call us or a pet emergency hospital when something seems unusual (see “What to Watch For” below). Be sure to adhere to the schedule of examinations and vaccinations that we recommend for her. This is when we’ll give her the necessary “check-ups” and test for diseases and conditions that are common in Bullmastiffs. Another very important step in caring for your pet is signing up for pet health insurance. There will certainly be medical tests and procedures she will need throughout her life and pet health insurance will help you cover those costs.

Routine Care, Diet, and Exercise

Build her routine care into your schedule to help your Bully live longer, stay healthier, and be happier during her lifetime. We cannot overemphasize the importance of a proper diet and exercise routine.

Supervise your pet as you would a toddler. Keep doors closed, pick up after yourself, and block off rooms as necessary. This will keep her out of trouble and away from objects she shouldn’t put in her mouth.
She has low grooming needs. Brush her coat as needed, at least weekly.
Bullmastiffs generally have good teeth, and you can keep them perfect by brushing them at least twice a week!
Clean her ears weekly, even as a puppy. Don’t worry—we’ll show you how!
Naturally a bit wary, she’s distrustful of strangers; bond her to children early to trigger protective behaviors.
She can have a high prey drive, so she needs to be leash walked and a sturdy fence is a must.
She can be sensitive to temperature extremes; avoid any prolonged exposure and be very alert to the signs of heat stress.
Keep your dog’s diet consistent and don’t give her people food.
Feed a high-quality diet appropriate for her age.
Exercise your dog regularly, but don’t overdo it at first.
What to Watch For

Any abnormal symptom could be a sign of serious disease, or it could just be a minor or temporary problem. The important thing is to be able to tell when to seek veterinary help, and how urgently. Many diseases cause dogs to have a characteristic combination of symptoms, which together can be a clear signal that your Bullmastiff needs help.
