English Mastiff Breed Guide: Temperament, Care and Health

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

The English Mastiff is among the heaviest dog breeds, a massive, calm giant with a broad head, a dark mask and a gentle heart. It is loyal and dignified, and it needs space and committed care.

Origins and appearance

Mastiff-type dogs were used in Britain for guarding and in ancient times as war dogs. The modern English Mastiff was preserved and rebuilt in the twentieth century. They are huge and heavily boned, with a broad skull, a short, dense coat in fawn, apricot or brindle, a black mask and drooping jowls.

Temperament

They are calm, loyal and gentle. They bond closely with family and are protective. They are reserved with strangers. They are usually good with children but can knock over small ones. They can be stubborn. They dislike being left alone.

Exercise

They need moderate exercise, such as daily walks. They prefer cool weather. Avoid heavy exercise in heat or while growing. Keep them lean.

Training

They are intelligent but can be slow and stubborn. Use positive methods and early socialization. Teach leash manners before the dog is large. House training can take time.

Coat and grooming

The short coat needs weekly brushing. See short coat dog grooming guide. Wipe the face and drool, clean ears and skin folds, trim nails and brush teeth.

Health considerations

Topics include:

• Bloat. See bloat and GDV in dogs
• Hip and elbow dysplasia. See hip dysplasia in dogs
• Heart disease, including cardiomyopathy
• Cancer. See signs of cancer in dogs
• Eyelid problems, such as entropion and ectropion
• Heat sensitivity. See dog heatstroke
• Cystinuria

Living with an English Mastiff

They suit families with space and cool conditions. They are poorly suited to small homes and hot climates.

A typical day

A Mastiff walks, naps for much of the day and enjoys family time. They like to be near people.

Puppies and the first year

Puppies are large and clumsy. Begin socialization, handling and training. Avoid stairs and heavy exercise while growing. See puppy socialization checklist.

Costs and commitment

Plan for food for a giant dog and significant vet costs. See dog vet cost guide.

Seasons and travel

They suffer in heat and need shelter in cold. Travel requires a very large vehicle.

Common mistakes

Common mistakes include exercising in heat, overfeeding puppies, ignoring socialization and underestimating size.

Choosing a puppy or adult

Ask about hip, elbow and heart tests, and lifespans in the lines. Meet the parents.

The weight of a giant

Large dogs need strong equipment, sturdy furniture and a car that fits them. Plan ahead for emergencies, since lifting a Mastiff is not a one-person job.

Short lives, big love

The breed's lifespan is relatively short. Talk with your vet early about care plans, consider insurance and make the most of the time you have together.

Daily care checklist

Plan on a gentle walk, weekly brushing, face and fold cleaning, nail trims and measured meals. Provide cool resting areas and learn the signs of bloat.

Is it the right breed for you?

An English Mastiff suits owners with space who want a calm, gentle giant and accept drool and health costs. It may not suit small homes or hot climates. For a lighter relative, see the Bullmastiff.

Life with a very large dog

Everyday logistics matter more with a giant. Choose a bed big enough to stretch out on, raised bowls only if your vet recommends them and a crate or car that fits comfortably. Slippery floors can be hard on joints, so lay rugs or runners. A sling or harness with handles makes it easier to help an older dog stand. Plan for travel, boarding and emergencies well in advance.

Training the gentle giant

Mastiffs often respond best to calm voices, patience and small treats. Use short, upbeat sessions, and avoid physical corrections, which can harm the dog and the relationship. Start young, because it is much easier to teach a thirty-pound puppy to walk politely than a hundred-and-fifty-pound adult.

The takeaway

English Mastiffs are massive, calm and loyal, and they need space, cool weather and careful health care.
