English Mastiff: dog breed appearance, character, training, care, health


Among the characteristics of the Mastiff or English Mastiff dog breed, its enormous size and weight stand out. It is one of the largest dogs on the planet. Despite its imposing appearance, it is a pet with a calm, noble and very affectionate character. At Petlifey, we explain everything about the Mastiff breed .


Character of the Mastiff breed

The character of the mastiff dog, also called the English Mastiff or Old English Mastiff, shows great confidence and self – assurance. Its guardian instinct is very exacerbated, it is linked to its genetic inheritance, so it does not need to be trained for it.

Its behaviour is a combination of nobility and courage, it is a calm, serene and very affectionate animal with its owners, but at the same time an excellent guardian, always brave , alert and protective. Willing to corner any intruder who threatens its family.

Majestic dog, very powerful, strong, massive and imposing. Because of its personality and on its own initiative, it defends its family and its territory to the last consequences. When it perceives the presence of a stranger, it follows them and corners or immobilizes them with the powerful force of its body.

But, at the same time, as we have mentioned, it has the personality of a calm animal, little barking, affectionate and patient, especially with children , and it also likes to please its owner, so its training is not difficult.

This dog has such a calm temperament that it even has a certain inclination to be lazy or to lie down all day, presiding over its surroundings with its majestic and superb figure.

Even so, it is advisable for its owner to educate it with a firm hand and patience, trying to promote good socialization when it is still a puppy, to avoid accentuating its suspicion towards strangers.

As it is a very large dog, it is not the most suitable pet to live in an apartment, although it does not require large spaces on which to dominate with its imposing presence and where it can run and exercise.

In fact, its large size is the biggest “drawback” of this breed, apart from the fact that, if it lives indoors, it may end up impregnating everything with its drool.

But for everything else it makes an excellent, calm, patient and affectionate companion dog, who can be fully entrusted with the care of both the house and all its components.

In the case of wanting to buy a puppy, it is very important that you do it in a specialized and professional kennel. Don’t be tempted by an excessively “cheap” English Mastiff price. Sometimes it is a bad decision.

In the same way, you should be aware that the puppies of this breed need vitamin and mineral supplements during growth for their proper development. This complements their diet, based on the highest quality dry feed.

Calm and almost lazy in nature, in order for the Mastiff to stay healthy and in good physical condition it is important to force it to do some activity, such as long walks and, from time to time, some exercise session in freedom.

Likewise, it is very important to start your education and socialization from an early age. In this way it will know the rules of the house and will not get nervous before unfamiliar situations.


Education and training of the English Mastiff

Regarding how to train an English Mastiff, you should know that it is not a very suitable breed for those who are weak or insecure. Since this canine pet needs a confident owner.

The owner must teach them to act like a well-trained dog and has to give them long walks so that it can expend its energy. In addition, the animal must be a participant in family life, being one more, and feeling that it is respected and loved.

As it is a very large pet, it likes to live both in the garden and indoors. Similarly, surprisingly enough, it is a dog who loves obstacle courses.

This well-behaved dog is ideal for living with children, as it is patient and tender. The smallest of the house will have it as if it were a huge stuffed animal.

Training an English Mastiff is not complex, but you must be aware that it is essential to be firm and constant in your orders and indications of behaviour.

It is very important to use positive reinforcement with this breed of dog. That is, reward and praise when it does something right, instead of yelling at them or being rude when it does something wrong. Rigorous training methods have proven useless.

If you see that it is about to do something that it should not, avoid saying a “NO” in a firm tone, but without yelling. For example, if it was trying to chew on a piece of furniture, say “no” and bring one of its toys closer to them so it can chew on it and play with it.

In short, the perfect owner for a mastiff is one who has an iron or firm demeanor, but is capable of being both loving and fair to the animal.
