Mastiff Common Health Issues

One common health issue of these dogs is hip dysplasia. When a dog has this condition, its thigh bone doesn’t fit into the hip joint in the proper way. This can lead to arthritis and mobility issues. Another common health issue is elbow dysplasia. Elbow dysplasia is an inherited condition and occurs when the bones and cartilage in the dog’s elbow joint don’t fit together properly.

Mastiffs are vulnerable to several eye issues. One of them is called progressive retinal atrophy. This condition occurs when the photoreceptor cells in the dog’s eyes start to deteriorate. It can lead to partial or full vision loss.

The most common health issues of these dogs include:

  • Hip Dysplasia
  • Elbow Dysplasia
  • Progressive Retinal Atrophy

Mastiff Temperament and Behavior

These dogs have an affectionate, friendly personality. This is what makes them good family dogs. They fit in best with families who have older children. At times, this dog’s behavior can be described as that of a couch potato. They’d like nothing more than to sit on the couch next to their owner. However, these dogs need regular exercise such as a walk in the woods, a game of chase in the backyard, or fetching a ball to stay in good health.

One of the most notable traits of this breed is its sensitive nature. They have a talent for reading the facial expressions of their owners. They are people pleasers! This makes obedience training a relatively easy process. But, keep in mind, when an owner speaks with a harsh tone, this dog’s feelings will be hurt. It’s best for an owner to use treats and words of praise with a mastiff during obedience training.

How to Take Care of a Mastiff

As with any breed of dog, this dog needs a certain type of care to maintain good health. For instance, feeding this pet a balanced diet throughout its life can help to prevent the common health issues mentioned above. Furthermore, puppy and adult mastiffs both need the proper amount of exercise each day to stay in shape.

Mastiff Food and Diet

Not surprisingly, a puppy requires a different diet than an adult dog. Look at the specific ingredients in the feeding routines of puppies and adult dogs.

Mastiff puppy food: The goal of quality puppy food is to promote a slow rate of growth. It’s important for a puppy’s joints, bones, muscles, and tendons to gain strength gradually. This can prevent health problems like hip and elbow dysplasia brought on by a puppy gaining too much weight too quickly. Protein is the main ingredient in quality mastiff puppy food. It builds muscle and contributes to the health of a puppy’s skin and coat. It also provides energy to a puppy without adding needless weight. Calcium is important for the proper growth of bones and teeth. DHA is another ingredient important for brain development and continued eye health. DHA is an ingredient that can work to prevent progressive retinal atrophy.

Mastiff adult dog food: Protein is an important ingredient in an adult’s food as well. This nutrient gives the dog energy and continues to build strong bones and muscles in an effort to prevent hip and elbow dysplasia. Omega-3 and Omega-6 fatty acids contribute to an adult dog’s healthy coat and skin. Antioxidants in the food support the dog’s immune system.

Mastiff Maintenance and Grooming

How much does a mastiff shed? The English, Neapolitan, and Bullmastiff are all moderate shedders. The Tibetan mastiff sheds very little while its cousin the French mastiff is a heavy shedder. These dogs shed more during the change of seasons. These dogs have a double coat of short hair. The daily grooming routine of this breed of dog is relatively easy. A soft brush with boar’s hair bristles is excellent for removing loose or dead hair from this dog’s coat.

A grooming glove is another effective tool especially when it comes to removing loose hair from the dog’s legs and wrinkly face. A grooming glove offers more control while working around the dog’s ears, nose, and eyes. It’s best to brush the dog starting at the head and ending at its tail. This helps an owner brush the hair in its natural direction.

An owner should be on the lookout for skin conditions including patches of dry skin, bald spots, and itchy areas. These can be caused by food or skin allergies or even using a shampoo with ingredients that irritate the dog’s skin.

Mastiff Training

All mastiffs including the Bull, English, French, Italian, Neapolitan, and Tibetan share a sensitive nature. They are relatively easy to train but need an owner to be firm without using harsh words. An owner who uses a harsh tone is not likely to have success in training a mastiff. Words of praise and treats go a long way to effectively conveying obedience lessons to a mastiff. A Great Dane is another large dog with a sensitive nature. It’s relatively easy to train as well when an owner uses words of praise and rewards.

Mastiff Exercise

Though these dogs are not high energy dogs, they need daily exercise to control their weight and avoid developing bone, joint, and muscle health issues. Twenty to thirty minutes of exercise per day is a good amount for a mastiff. An ideal exercise routine is a slow walk through the woods or the neighborhood. An owner should avoid jogging with a mastiff because these dogs can become overheated in a short time.

Though these dogs aren’t overly active, it’s not a good choice for apartment life. Its large size would not be suitable for a small living space. This breed needs a backyard where it can stretch its legs and get some fresh air for part of the day.

Mastiff Puppies

A mastiff puppy should never be overfed. When a mastiff puppy grows and gains weight too quickly, it puts them at risk for developing health issues. Their bones, muscles, and joints need time to develop so they can fully support their large adult body.

These puppies need daily exercise just as adult dogs do. Twenty minutes of walking per day can help a puppy to burn fat.

Mastiffs and Children

These dogs are good family dogs and do well with children in a home. These are affectionate, gentle dogs. However, it’s a good idea for a family with small children to get a mastiff puppy. That way, the mastiff has an opportunity to learn how to interact with small children and become accustomed to their behavior.

Dogs Similar to a Mastiff

Some breeds similar to the mastiff include the Great Dane, the Boxer, and the Irish Wolfhound.

  • Great Dane – Great Danes and mastiffs are both large dogs. They are both sensitive and friendly. However, Great Danes are a little more energetic than mastiffs.
  • Boxer – Boxers and mastiffs do well with children and have a simple grooming routine due to their short-haired coat. Boxers tend to be a little more playful than mastiffs.
  • Irish Wolfhound – Irish Wolfhounds are affectionate with a sweet nature like mastiffs. Both these dogs don’t like to be left alone and suffer separation anxiety. An Irish Wolfhound is not as good a guard dog like a mastiff.
