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 Spanish Mastiffs and you expected her to have certain traits that would fit your lifestyle:
Protective of owners; excellent guard dog
Good with children
Large, strong, and athletic
Docile and devoted
Confident, steady, and fearless
Affectionate, easygoing, and lovable
However, no dog is perfect! You may have also noticed these characteristics:
Can be rambunctious and rowdy, especially as a puppy
Needs daily exercise
Overprotective of family and territory if not socialized properly
Can be gassy and drool a lot
Early obedience training and socialization is recommended
Sensitive, matures slowly
Is it all worth it? Of course! She’s full of personality, and you love her for it! Massive and dignified, she makes for an impressive pet. With a consistent leader and regular exercise, she can make an excellent companion and guardian.
Deriving from Spain, these Mastiffs were bred to protect their livestock. The large neck folds you love actually served to keep her safe in battles when protecting the herd. They are now the official breed of Spain and are used in military and police work. Their large size and loud bark can make them a challenge to keep in small quarters. With proper socialization, these noble giants grow into great cuddle buddies and loyal companions.
Your Spanish Mastiff’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 Mastiff. By knowing about health concerns specific to Spanish Mastiffs, 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 inSpanish Mastiffsto 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 Spanish Mastiffs. 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 Spanish Mastiff 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 Spanish Mastiff
Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. And unfortunately, your Spanish Mastiff 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 Mastiff’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.
Spanish Mastiffs 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, herage, and other factors.
Obesity can be a significant health problem in Spanish Mastiffs. It is a serious disease that may causeor 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!
All kinds of worms and bugs can invade your Spanish Mastiff’s body, inside and out. Everything from fleas and ticks to ear mites can infest herskin and ears. Hookworms, roundworms, heartworms, and whipworms can get into hersystem 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 herhealthy.
Spay or Neuter
One of the best things you can do for your Mastiff 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 Spanish Mastiffs
Suspected Disease Risks
If you have a common dog breed, there’s probably a lot of genetic research and clinical epidemiological data that have been collected and analyzed over the years, and this large amount of data means that we can confidently predict higher than average risk of certain diseases for these breeds. When the dog breed is more rare, or has not been studied because of geographic or other isolation, we have no stockpile of documented history to draw upon when making preventive healthcare recommendations. We can however, make some educated guesses based on disease risks for dog breeds that share conformational or genetic links with your Spanish Mastiff. Based on these similarities, the following disease risks may carry higher risk, although supportive research has not been identified.
Bone and Joint Problems
A number of different musculoskeletal problems have been reported in Spanish Mastiffs. 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 Mastiffs 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.
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 Mastiff’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!
When Mastiff 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.
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 Spanish Mastiff. 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.
Gastric Dilatation and Volvulus, also known as GDV or Bloat, usually occurs in dogs with deep, narrow chests. This means your Mastiff 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!
Cancer is a leading cause of death among dogs in their golden years. Your Spanish Mastiff 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.
Spanish Mastiffs 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.
A genetically linked neurological condition that could occur in your Spanish Mastiff 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.
Entropion is a condition where the eyelid rolls inward, causing the eyelashes to rub against the cornea (surface of the eyeball). This is an extremely irritating and painful condition that can ultimately lead to blindness. It can happen in any dog breed; however, your Mastiff is especially at risk for this heritable disorder. Surgical correction is usually successful if performed early.
Your Spanish Mastiff is prone to a form of skin infection called lip-fold pyoderma, which occurs because the folds of skin along the lower jaw are usually moist. Bacteria and yeast can readily gain a foothold and cause a reddened, smelly area that is uncomfortable for your dog. We will examine him for this problem, but let us know if you see signs. We’ll recommend treatment with antibiotics as necessary. When symptoms are severe, the excess skin folds can be surgically removed.
Mastiffs are prone to a common condition called hypothyroidism in which the body doesn’t make enough thyroid hormone. Signs can include dry skin and coat, hair loss, susceptibility to other skin diseases, weight gain, fearfulness, aggression, or other behavioral changes. We’ll conduct a blood screening test annually to screen for the disease. Treatment is usually simple: replacement hormones given in the form of a pill.
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 Spanish Mastiff, speak with us first. We can help you make an informed decision based on body conformation of both sire and dam.
Taking Care of Your Spanish Mastiff 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 Mastiffs. 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 Spanish Mastiff 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 could use a thorough brushing at least every couple weeks most of the year. More when she blows her coat in fall and spring.
Spanish Mastiffs 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!
She has a tendency to be lazy so you must ensure she receives adequate exercise by providing daily walks.
It is recommended that you provide her with soft bedding to help prevent joint problems and calluses.
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 Spanish Mastiff needs help.
Give us a call for an appointment if you notice any of these types of signs:
Change in appetite or water consumption
Tartar build-up, bad breath, red gums, or broken teeth
Itchy skin (scratching, chewing, or licking), hair loss
Lethargy, mental dullness, or excessive sleeping
Fearfulness, aggression, or other behavioral changes
Dull coat, hair loss, sluggish, weight gain
Lumps or bumps – regardless of size
Seek medical care immediately if you notice any of these types of signs:
Scratching or shaking the head, tender ears, or ear discharge
Inability or straining to urinate; discolored urine
Cloudiness, redness, itching, or any other abnormality involving the eyes
Dry heaving or a large, tight, painful abdomen
Fainting, collapse, breathing issues, cough
General reluctance to run or play
Leg stiffness, reluctance to rise, sit, use stairs, jump, or “bunny hopping”
