Mastiff Breed Overview

The Mastiff is a giant-sized dog.

The adult Mastiff stands 27 to 32 inches tall at the shoulder.

The Mastiff belongs to the Working Dogs group.

Dogs in the Working Dogs group, like the Mastiff, were developed to assist humans in some capacity – including pulling sleds and carts, guarding flocks, guarding homes, and protecting their families.

Breeds in the Working Group are known for their imposing stature, strength, intelligence, and fearless.

Because of their size and strength, working dogs require a structured home life and firm, fair, consistent training by someone who can provide leadership without resorting to anger or physical force.

The fact that the Mastiff belongs to the Working Dogs group is one of the reasons why Mastiffs have the personality and temperament that they have.

The temperament of the Mastiff is generally described as:

  • Affectionate
  • Calm
  • Courageous
  • Dignified
  • Good-natured
  • Protective

History of the Mastiff Breed. Where Mastiffs came from

This selfless canine is a giant among dogs.

This colossus, the largest of the dog breeds, is a descendant of the Molosser family and was most likely brought to the British Isles aboard Phoenician trading ships between 2000 and 1500 BC.

The progenitor of the modern-day Mastiff was raised and bred as a fearsome guardian for the tribes living in the Isles over centuries and isolated on an island.

By the time the Romans invaded in 55 BC, these courageous canines were being used as war dogs in the resistance against Rome.

Julius Caesar was so impressed with the dog`s size and bravery that he brought a pack back to Rome to fight lions and gladiators.

The Mastiff`s role as a protector and guardian remained unchanged over the centuries.

How Intelligent are Mastiffs?

Mastiff
Intelligence Rank 72 out of 130 dog breeds
Trainability Tend To Learn New Commands After 80 To 100 Repetitions Or More!

According to Prof. Stanley Coren, a Canadian psychology professor/dog trainer, the total intelligence that a dog demonstrates is the addition of three types of intelligence. These intelligence types are:

  1. Instinctive Intelligence: This is the natural intelligence that comes from instinct. For example, dog breeds that have been historically bred to be guard dogs will have a high `guarding` intelligence compared to dogs that were not bred for guarding.

  2. Adaptive Intelligence (learning and problem-solving ability): This indicates what a dog can learn to do for himself or herself. Adaptive intelligence is specific to each dog, and not breed specific. You can improve your dog`s adaptive intelligence by investing time to train your dog.

  3. Working/Obedience Intelligence: This type of intelligence is breed-specific. Certain dog breeds tend to have higher working/obedience intelligence than some other breeds. This intelligence is the closest to what we might call school-learning ability and it is based upon what the dog can learn to do when instructed by humans. This type of intelligence can be measured for each dog breed and compared to that of other dog breeds.

Professor Stanley Coren measured and ranked the working intelligence of about 130 different dog breeds.

Prof. Coren found that the Mastiff has an obedience intelligence rank of 72 out of 130 dog breeds. Thus, Prof. Coren put Mastiffs in the `Lowest Degree of Working/Obedience Intelligence Dogs` category.

This means that Mastiffs tend to learn new commands after 80 to 100 repetitions or more!.

However, we should mention that a dog should not be judged based on its intelligence alone. There are other important factors you need to consider when deciding on which dog breed to get. These other factors include sociability, adorability, and compatibility of the dog breed with your lifestyle.

Health Problems in Mastiffs and How to Prevent Them

Every dog breed has its own set of health problems that it tends to develop. There is nothing like a perfect dog breed.

The Mastiff is prone to certain genetic health conditions. The Orthopedic Foundation for Animals (OFA) is an organization that keeps track of genetic health problems in dog breeds.

From the extensive records that the OFA keeps, the OFA knows what health problems each dog breed is naturally prone to develop.

Hence, the OFA recommends which health screening breeders should perform on a dog breed to make sure that the breeders won`t breed `defective` dog parents that can pass down defective genes to their puppy offspring.

If you want a Mastiff puppy that will grow up to be healthy, make sure that your Mastiff breeder screens your puppy or your puppy`s parents for the health problems that the OFA recommends for your puppy`s breed. This will increase the chances that your puppy is free from genetic defects.

The following are the health tests that Orthopedic Foundation for Animals (OFA) recommends that breeders should screen Mastiffs for:

  1. Autoimmune thyroiditis
  2. Cardiac Evaluation
  3. Cystinuria
  4. Elbow Dysplasia
  5. Eye Examination- Minimum age 24 months
  6. Hip Dysplasia
  7. PennGen
