Your Neapolitan Mastiff

Caring for Your Faithful Companion

Neapolitan Mastiffs: What a Unique Breed!

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 Neos and you expected her to have certain traits that would fit your lifestyle:

  • Formidable guard dog; highly territorial
  • Trusting and affectionate
  • Confident, steady, and fearless
  • Even temper and gentle disposition
  • Quiet—not much of a barker
  • Devoted, loyal, and protective

However, no dog is perfect! You may have also noticed these characteristics:

  • Can be rambunctious and rowdy, especially as a puppy
  • Willful and stubborn if you don’t show strong leadership
  • May be aggressive toward people and dogs
  • Can be gassy and drool a lot
  • Makes a lot of snorting, snuffling, and wheezing noises, and she may snore
  • Prone to boredom and separation anxiety when left alone and will find trouble

Is it all worth it? Of course! She’s full of personality, and you love her for it! She is usually watchful and calm, but she can be dominant and jealous. With early socialization and training she is a loving and peaceful family pet.

The Neapolitan Mastiff can trace its roots back to the Roman Army, but are better known as estate guard dogs in Italy. They are commonly referred to as “Italian Mastiffs” or “Mastinos.” The Neo is instinctively protective and watchful of its family and territory. They have a moderate energy level and can seem lazy, but are able to spring into action if needed. Neapolitan Mastiffs are slow to mature, and they remain in puppyhood until they are three years old. Neos love children, but their large size can cause accidents. The Neapolitan Mastiff is not recommended for first-time dog owners or families with small children. With strong leadership, they are an intelligent, mild-mannered, and affectionate companion.

Your Neapolitan 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 Mastino. By knowing about health concerns specific to Neapolitan 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 in Neapolitan Mastiffs 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 Neapolitan 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 Neo 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 Neapolitan Mastiff

Dental Disease

Dental disease is the most common chronic problem in pets, affecting 80% of all dogs by age two. And unfortunately, your Neo 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 Neo’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

Neapolitan 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, her age, and other factors.

Obesity

Obesity can be a significant health problem in Neapolitan Mastiffs. 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 Neo’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 Mastino 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.

Gastric Dilatation and Volvulus

Gastric Dilatation and Volvulus

Genetic Predispositions for Neapolitan Mastiffs

Bloat

Gastric Dilatation and Volvulus, also known as GDV or Bloat, usually occurs in dogs with deep, narrow chests. This means your Mastino 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!

heartNormalInsidesHeart Disease

Neapolitan 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.

Mastinos are susceptible to a condition called Patent Ductus Arteriosis, in which a small vessel that carries blood between two parts of the heart does not close shortly after birth as it should. This results in too much blood being carried to the lungs, fluid build-up, and strain on the heart. Outward signs may be mild or you may see coughing, fatigue during exercise, weight loss, shortness of breath, or weakness in the hind limbs. We listen for a specific type of heart murmur to diagnose this problem during his examinations. If your pal has this condition, we may recommend surgery to close the problematic vessel.

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, Neapolitan Mastiffs 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.

Cataracts are a common cause of blindness in older Mastinos. We’ll watch for the lenses of his eyes to become more opaque—meaning they look cloudy instead of clear—when we examine him. Many dogs adjust well to losing their vision and get along just fine. Surgery to remove cataracts and restore sight may also be an option.

Prolapse of the third eyelid gland (cherry eye).

Prolapse of the third eyelid gland (cherry eye).

Dogs have a third eyelid that contains a gland that produces about one-third of the fluid that bathes the eye. If the gland is sore or swollen, it looks like a red blob in the corner of the eye. This condition is called cherry eye, and it can occur very suddenly in one or both eyes. It’s more common in puppies or young Mastinos. If this happens to him, we may treat it with ointment first, but surgery is often the best option.

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 Mastino is especially at risk for this heritable disorder. Surgical correction is usually successful if performed early.

Ectropion is a defect where the eyelids droop or hang away from the eye. While ectropion can cause those sad looking puppy dog eyes, the problem more importantly exposes the eye to environmental contaminants and leads to irritation, drying, and can progress to eye infections. Mastinos are a bit more likely than other dogs to show this deformity. The good news is it can usually be surgically corrected.

Progressive Retinal Atrophy (PRA) is an inherited disease in which the eyes are genetically programmed to go blind. Unfortunately, Neapolitan Mastiffs are a bit more likely than other dogs to have this condition. PRA is not painful, but also not curable. In dogs with the bad gene, early symptoms such as night blindness or dilated pupils generally begin around three to five years of age. A genetic test is available for this condition.

Bone and Joint Problems

A number of different musculoskeletal problems have been reported in Neapolitan 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.

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 Mastino’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!

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 Neo. 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.

Growing Mastinos 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 Mastino 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.

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 Mastinos 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.

Mange

Demodex is a microscopic mite that lives in the hair follicles of dogs. All dogs have them. Normally a dog’s immune system keeps the mites in check, but some breeds, like your Mastino, develop an overabundance of these mites. In mild cases, pet owners may notice a few dry, irritated, hairless lesions. These often occur on the face or feet and may or may not be itchy. Secondary skin infections may occur. Prompt veterinary care is important to keep the disease from getting out of hand. Many pets seem to outgrow the problem, while others require lifelong management.

Skin Infections

Your Neapolitan 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.

Thyroid Problems

Mastinos 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.

Retained Testicle

Some male Mastinos have a condition present at birth in which one or both testicles do not descend into the scrotum (a condition called cryptorchidism). Instead, the testicle stays in the abdomen, which can cause problems later in life, including high cancer risk. We’ll check for this problem when your pet is a puppy; we recommend removal of both testicles if he has this condition.

Tumors, both benign and cancerous, can look like anything. This red swelling on the skin surface is a cancer known as a Mast Cell Tumor. Be sure to have all lumps and bumps checked out.

Cancer

Cancer is a leading cause of death among dogs in their golden years. Your Neapolitan 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.

NeapolitanMastiff2of2Taking Care of Your Neapolitan 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 Mastinos. 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 Neo 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.
  • Neapolitan 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 and ample room to play.
  • She can be sensitive to warm temperatures; avoid any prolonged exposure and be very alert to the signs of heat stress.
  • Check her eyes and skin folds often, be sure to keep them clean.
  • 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 Neapolitan Mastiff needs help.

Office calls

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

Emergencies

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
  • Fatigue during exercise, coughing, or shortness of breath
  • General reluctance to run or play
  • Dry, scaly, sometimes itchy hairless patches on face or paws
  • Dull coat, hair loss, sluggish, weight gain
  • Leg stiffness, reluctance to rise, sit, use stairs, run, jump, or “bunny hopping”
