Mastiff Versus Shetland Sheepdog: Introduction

Are you thinking of getting a new pet dog, and you have narrowed down your choices to the Mastiff and the Shetland Sheepdog? Well, you have come to the right place. Because in this article, we will provide you with a detailed comparison of these two dog breeds to help you decide which of the Mastiff and the Shetland Sheepdog better suits you.

We will provide you a detailed discussion and comparison of dog attributes such as intelligence, price, general health, friendliness, etc, for both the Mastiff and the Shetland Sheepdog.

Furthermore, we will let you know which one of the Mastiff and the Shetland Sheepdog is better suited for new dog owners, for owners with kids, for owners that live in apartments, for owners with dog allergies, etc.

Importantly, we did some analysis and calculation and we obtained a number that we call the Better-Pet Score™ for both the Mastiff and for the Shetland Sheepdog. The dog breed with the higher Better-Pet score is the `better` pet. We hope that these Better-Pet Scores will provide you with more insight into deciding which pet to get between the Mastiff and the Shetland Sheepdog.

Our only goal here is to help you make a well-thought-out decision on your next long-term companion, be it the Mastiff or the Shetland Sheepdog.

Mastiff versus Shetland Sheepdog

Mastiff versus Shetland Sheepdog: Overview

A very important difference between the Mastiff and the Shetland Sheepdog is the size difference between the two dog breeds. The Mastiff is a giant-sized dog while the Shetland Sheepdog is a small-sized dog.

Furthermore, the Mastiff belongs to the Working Dogs group. Working Dogs 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.

On the other hand, the Shetland Sheepdog belongs to the Herding Dogs group. Herding Dogs were bred for moving livestock, including sheep, cattle, and even reindeer. Herding dogs work closely with their human shepherds, and their natural intelligence and responsiveness make them highly trainable. They have high levels of energy, which needs to be channeled properly to prevent destructive behavior. Herding breeds are protective of their people and property and make excellent watchdogs. Their intelligence, agility, and activity level make them well suited to dog sports.

Mastiff versus Shetland Sheepdog: Comparison Table

The table below compares the Mastiff to the Shetland Sheepdog based on different important factors such as Price, Health, Kid-friendliness, etc.

When a dog breed scores higher for a factor than the other dog breed, the box of the breed that scores higher is shaded green and the box of the breed that scores lower is shaded red. When there is no difference between the breeds for a particular factor then the box is shaded gray for both pets. Also, when the factor is not important in picking a pet, or when the factor cannot be compared between two pets, the box for the factor is shaded gray for both pets

Most of the factors in the table for each dog breed are ranked on a scale of 1 to 5. “1” means “worst”, and “5” means “best”.

However, some factors such as “Price”, “Average Lifespan”, etc. cannot be on a scale of 1 to 5, so they are not on a scale of 1 to 5 in the comparison table.

Later in this article, we will further explain each factor as it applies to the Mastiff and the Shetland Sheepdog

    Next, we added the scores of the factors that can be added together for the Mastiff in the table (that is, `Ease of Grooming` score + `General Health` score + `Calmness` score + …etc) and we compared it to the corresponding total score for the Shetland Sheepdog. We call these total scores the Better-Pet Scores, as we mentioned earlier. We called this score the Better-Pet score because the better dog breed will have a higher score. This is because the pet will the higher score will have minimal needs and be easier to have as a pet.

    The Better-Pet score for the Mastiff is 72 out of 125 while the Better-Pet score for the Shetland Sheepdog is 85 out of 125.

    Based on their Better-Pet scores, the Shetland Sheepdog is a better pet than the Mastiff. So, you should get the Shetland Sheepdog!

    Although we have done our best to analyze these two dog breeds in a very unbiased way, however, we will like to let you know that there are some dog attributes that cannot be assigned a number for comparison. We cannot put a number on how cute a dog breed is, for example. Beauty is in the eye of the beholder.

    Also, the dog breed that best suits you will depend on your peculiar lifestyle, your taste, and your priorities, which we do not know. So, for you to decide on which breed is right for you, read through the rest of the article to further understand both the Mastiff and the Shetland Sheepdog so that you can make your own well-informed decision on which pet to get.

    This is because the temperament score for the Mastiff is 100.0 percent while the temperament score for the Shetland Sheepdog is 68.9 percent, according to the American Temperament Test Society (ATTS).

    The American Temperament Test Society (ATTS) is a non-profit organization whose mission is to provide fair and objective evaluations of the temperaments of dog breeds.

    Dog breeds with low temperament scores tend to show unprovoked aggression, they easily panic without quickly recovering from the panic, and they tend to avoid people. However, dog breeds with high temperament scores are not aggressive and are not shy. Also, these dogs are generally friendly and are protective of their owners.

    The average temperament score across all dog breeds (over 250 breeds) is 83.7 percent.

    With its temperament score of 100.0 percent, the Mastiff has an above-average temperament compared to other dog breeds.

    Note that a lot of factors determine how much you can expect to pay for the Mastiff puppy or the Shetland Sheepdog puppy. This includes if health screening tests have been performed on the puppy, if the puppy is from a famous pedigree, the US State where the puppy is bred, etc.

    Nevertheless, when looking to buy a puppy, look at buying a puppy only from well-established breeders that breed puppies primarily for the love of dogs, and secondarily for profit. Do not buy a puppy from a puppy mill. Puppy mills mass-produce puppies in bad living conditions for maximum profit.

    You may also consider adopting a dog instead of buying a dog.

    The Intelligence of the Mastiff versus the Intelligence of the Shetland Sheepdog

    Mastiff Shetland Sheepdog
    Intelligence Rank 72 out of 130 dog breeds 6 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 80 To 100 Repetitions Or More! Tend To Learn New Commands After Fewer Than 5 Repetitions

    Professor Stanley Coren, the famous psychology/neuropsychological professor and, dog lover/trainer measured and ranked the intelligence of about 130 different dog breeds.

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

  • Instinctive Intelligence: This is the natural intelligence a dog has because of what the dog was bred for. This type of intelligence comes from instinct. For example, dog breeds that were bred for guarding will have high `guarding` instinctive intelligence, while dog breeds that were bred for hunting will what high `hunting` instinctive intelligence. However, you cannot compare the intelligence of dog breeds based on instinctive intelligence because such a comparison will not make sense.
  • Adaptive Intelligence (learning and problem-solving ability): This indicates what a dog can learn to do for himself or herself. It includes learning and benefiting from experience with his environment, solving new problems, and so forth. Adaptive intelligence is specific to each dog, and not breed specific. Thus, two dogs can have remarkably different levels of adaptive intelligence even if they are of the same breed.
  • Working/Obedience Intelligence: 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. Importantly, different dog breeds have different learning abilities. Also, science has shown that some dog breeds can learn faster than some other breeds. This means certain dog breeds tend to have higher working/obedience intelligence than some other breeds. Dogs with high Working/Obedience Intelligence are smart and easy to train.
  • Prof. Coren showed that the Working/Obedience Intelligence of different dog breeds can be measured reliably. Thus, he was able to rank different dog breeds based on their Working/Obedience Intelligence.

    This is important because according to Prof. Coren, 51 percent of a dog`s intelligence comes from its genes while 49 percent of a dog`s intelligence comes from the dog`s environmental circumstances.

    To rank the intelligence of dog breeds, Prof. Coren employed the help of 208 dog obedience judges in North America to fill out a detailed survey on dog obedience. This number represented more than half of all of these judges in North America at the time. He also employed 63 veterinarians and 14 guard dog experts to collect data on the personality of different dog breeds.

    Prof. Coren found that the Mastiff has an obedience intelligence rank of 72 out of 130 dog breeds. The Mastiff belongs to 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!.

    The Shetland Sheepdog has an obedience intelligence rank of 6 out of 130 dog breeds. The Shetland Sheepdog belongs to the `Brightest Dogs` category. This means that Shetland Sheepdogs tend to learn new commands after fewer than 5 repetitions.

    The Shetland Sheepdog is more intelligent than the Mastiff.

    However, Prof. Coren noted that a dog should not be judged based on its intelligence alone, that other factors such as sociability, adorability, and compatibility with the owner are other very important factors that new dog owners need to consider when deciding on a new dog.

    The Popularity of Mastiff versus Popularity of Shetland Sheepdog

    Every year, the American Kennel Club (AKC) publishes information on how popular a dog breed is in that particular year. The AKC gets the popularity information of a breed from how many dogs of that breed the owners register with the AKC every year. The AKC collects this data for about 200 dog breeds. The AKC collects this data for purebred dogs only(no mixed or hybrid dogs).

    The graphs and the table below show the popularity of the Mastiff and the Shetland Sheepdog over the years.

    Based on the AKC popularity data over the years, the Shetland Sheepdog is more popular with dog owners than the Mastiff. This is because, over the years, the average popularity of the Shetland Sheepdog is 23 out of about 200 dog breeds while the average popularity of the Mastiff is 28 out of about 200 dog breeds.

    Health Problems of Mastiff versus Health Problems of Shetland Sheepdog

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

    Both the Mastiff and the Shetland Sheepdog are prone to certain genetic health conditions. The Orthopedic Foundation for Animals (OFA) is the organization that keeps track of health problems in dogs. Based on 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 that 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.

    The more health problems a dog breed is prone to develop, the more health tests the OFA will recommend for that dog breed.

    Based on our review of OFA records, we found that the Mastiff is prone to more genetic health problems than the Shetland Sheepdog.

    This is because the OFA recommends more screening health tests for the Mastiff than for the Shetland Sheepdog.

    7 health tests are recommended for Mastiff while 4 tests are recommended for the Shetland Sheepdog.

    Below is a detailed discussion of health problems in Mastiffs and in Shetland Sheepdogs.

    Mastiff Health Problems

    Mastiffs are genetically prone to certain health problems. However, breeders can reduce the chances of producing Mastiff puppies with genetic defects by making sure that a puppy`s parents are free from genetic health problems before allowing the parent to make puppies.

    The OFA provides breeders recommendations on which genetic diseases that breeders should screen their dog parents and puppies for.

    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:

  • Autoimmune thyroiditis
  • Cardiac Evaluation
  • Cystinuria
  • Elbow Dysplasia
  • Eye Examination- Minimum age 24 months
  • Hip Dysplasia
  • PennGen
  • You can find out more about OFA`s recommended tests for Mastiffs here.

    Shetland Sheepdog Health Problems

    Shetland Sheepdogs are genetically prone to certain health problems. However, breeders can reduce the chances of producing Shetland Sheepdog puppies with genetic defects by making sure that a puppy`s parents are free from genetic health problems before allowing the parent to make puppies.

    The OFA provides breeders recommendations on which genetic diseases that breeders should screen their dog parents and puppies for.

    If you want a Shetland Sheepdog puppy that will grow up to be healthy, make sure that your Shetland Sheepdog 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 Shetland Sheepdogs for:

  • Cardiac Evaluation
  • Dentition
  • Eye Examination- Recommend evaluation every year until age 5, every 2 years thereafter until age 9.
  • Hip Dysplasia
  • You can find out more about OFA`s recommended tests for Shetland Sheepdogs here.

    *To learn more about each of these diseases, go to OFA.org and search for the disease.

    Again, most of these health problems can be prevented through health screening. Responsible breeders screen male and female dog parents for genetic problems. These breeders will only breed dogs that are free of genetic defects. That way, there is little or no chance that their puppies will grow up to have genetic health problems. Always ask a breeder for the list of health tests the breeder screens their dogs for before buying a puppy from such a breeder.
