Jack Russell Terrier versus Sealyham Terrier: Comparison Table

The table below compares the Jack Russell 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.

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.

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.

    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.

    The Intelligence of the Jack Russell Terrier versus the Intelligence of the Sealyham Terrier

    Jack Russell Terrier Sealyham Terrier
    Intelligence Rank 46 out of 130 dog breeds 56 out of 130 dog breeds
    Trainability Tend To Learn New Commands After 25 To 40 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 Jack Russell Terrier has an obedience intelligence rank of 46 out of 130 dog breeds. The Jack Russell Terrier belongs to the `Average Working/Obedience Intelligence Dogs` category. This means that Jack Russell Terriers tend to learn new commands after 25 to 40 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 Jack Russell 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.
