American Staffordshire Terrier versus Sealyham Terrier: Overview

A very important difference between the American Staffordshire Terrier and the Sealyham Terrier is the size difference between the two dog breeds. The American Staffordshire Terrier is a medium-sized dog while the Sealyham Terrier is a small-sized dog.

Furthermore, both the American Staffordshire Terrier and the Sealyham Terrier are Terrier Dogs. This means both the American Staffordshire Terrier and the Sealyham Terrier were originally bred to go underground to hunt rodents and other small wild animals (vermin). Terriers come in a wide range of sizes and shapes, but all terriers are energetic, highly intelligent, and territorial. Terries also have the tendency to escape. They require a securely fenced yard.

American Staffordshire Terrier versus Sealyham Terrier: Comparison Table

The table below compares the American Staffordshire Terrier to the Sealyham Terrier 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 American Staffordshire Terrier and the Sealyham Terrier

    Next, we added the scores of the factors that can be added together for the American Staffordshire Terrier 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 Sealyham Terrier. 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 American Staffordshire Terrier is 74 out of 125 while the Better-Pet score for the Sealyham Terrier is 80 out of 125.

    Based on their Better-Pet scores, the Sealyham Terrier is a better pet than the American Staffordshire Terrier. So, you should get the Sealyham Terrier!

    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 American Staffordshire Terrier and the Sealyham Terrier so that you can make your own well-informed decision on which pet to get.

    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 Intelligence of the American Staffordshire Terrier versus the Intelligence of the Sealyham Terrier

    `
    American Staffordshire Terrier Sealyham Terrier
    Intelligence Rank 34 out of 130 dog breeds 56 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 15 To 25 Repetitions Tend To Learn New Commands After 40 To 80 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 American Staffordshire Terrier has an obedience intelligence rank of 34 out of 130 dog breeds. The American Staffordshire Terrier belongs to the `Above Average Working Dogs` category. This means that American Staffordshire Terriers tend to learn new commands after 15 to 25 repetitions.

    The Sealyham Terrier has an obedience intelligence rank of 56 out of 130 dog breeds. The Sealyham Terrier belongs to the `Fair Working/Obedience Intelligence Dogs` category. This means that Sealyham Terriers tend to learn new commands after 40 to 80 repetitions!.

    The American Staffordshire Terrier is more intelligent than the Sealyham Terrier.

    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.

    Health Problems of American Staffordshire Terrier versus Health Problems of Sealyham Terrier

    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 American Staffordshire Terrier and the Sealyham Terrier 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 American Staffordshire Terrier is prone to more genetic health problems than the Sealyham Terrier.
