Norfolk Terrier Intelligence

How Smart is the Norfolk Terrier?

The Norfolk Terrier is a dog breed that is known to be:

  • Companionable
  • Fearless
  • Happy
  • Lovable
  • Self-confident
  • Spirited
  • Intelligent

But, how smart is the Norfolk Terrier really?

The Norfolk Terrier is the 56th smartest dog when it comes to obedience and working intelligence.

Accordingly, compared to other dogs, the Norfolk Terrier belongs to the `Fair Working/Obedience Intelligence Dogs` category.

Norfolk Terriers tend to learn new commands after 40 to 80 repetitions!.

These facts on Norfolk Terrier intelligence are from the published work on dog intelligence and behavior by the renowned Prof. Stanley Coren. Coren is a Canadian Psychology Professor and Dog Researcher.

In the 1990s, Prof. Coren did extensive scientific research where he `measured` what is called the Working or Obedience Intelligence of more than 130 different dog breeds.

Note that the working/obedience intelligence of a dog is one of the three intelligence components that constitute a dog`s total intelligence. But it is the only intelligence component that can be measured and compared among dog breeds.

Later on, we will further explain what the working/obedience intelligence means, and what the other two parts of a dog`s intelligence are.

For his research on measuring and ranking the intelligence of dog breeds, Prof. Coren consulted with:

  • Over two hundred dog obedience judges
  • Over sixty veterinarians, and
  • Fourteen guard dog experts

From his research data, Prof. Coren ranked dog breeds according to their obedience intelligence from the smartest to the least smart.

According to the study, the smartest dog breed is the Border Collie. Border Collies are so smart that they can understand any new command that you are trying to teach them after repeating the command to them five times or fewer.

The least smart dog breed is the Afghan Hound. The Afghan Hound is one of the dog breeds with the lowest degree of Working/Obedience intelligence. It will take 80 to 100 repetitions or more for an Afghan Hound to learn a new command.

As mentioned earlier, the Norfolk Terrier is the 56th smartest dog breed.

Furthermore, Coren placed dog breeds into one of six intelligence categories:

  1. Brightest Dogs: Tend To Learn New Commands After Fewer Than 5 Repetitions
  2. Excellent Working Dogs: Tend To Learn New Commands After 5 To 15 Repetitions
  3. Above Average Working Dogs: Tend To Learn New Commands After 15 To 25 Repetitions
  4. Average Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 25 To 40 Repetitions
  5. Fair Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 40 To 80 Repetitions!
  6. Lowest Degree of Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 80 To 100 Repetitions Or More!

The Norfolk Terrier belongs to the `Fair Working/Obedience Intelligence Dogs` category.

However, note that obedience intelligence is one of the many things that make a good dog. The fact that a dog breed has a low obedience intelligence DOES NOT MEAN the dog breed with not excel at other things.

Intelligence is just one of the many things that make dogs the excellent human companions that they are.

The Three Parts of the Intelligence of the Norfolk Terrier

As mentioned earlier, Prof. Coren ranked dogs based on what is called the `Working/Obedience` Intelligence.

The `Working/Obedience` Intelligence is one of the three parts of a dog`s overall intelligence.

All the three parts that make up a dog`s overall intelligence 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 or hunt dogs will have a high `guarding` or `hunting` intelligence compared to dogs that were not bred for guarding or hunting.

  2. You can tell what type of instinctive intelligence a dog breed will have based on the dog group the dog belongs.

    The Norfolk Terrier belongs to the Terrier Dogs group.

    Dogs in the Terrier Dogs group, like the Norfolk 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..

  3. Adaptive Intelligence: This indicates what a dog can learn to do for himself or herself. Adaptive intelligence is specific to each dog, and not specific to a dog breed. You can improve your dog`s adaptive intelligence (and therefore its overall intelligence) by investing time to train your dog.

  4. Working/Obedience Intelligence: This intelligence type is the subject of this article. This type of intelligence is breed-specific. Certain dog breeds tend to have higher working/obedience intelligence than 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. Furthermore, the working/obedience intelligence of one dog breed can be compared to that of another dog breed to see which dog is smarter

The natural breed-specific working/obedience intelligence is a heavy chunk of a dog`s overall intelligence.

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. Environmental circumstances include how much training you give to a dog.

In short, it will be much easier to train a naturally smart dog.

However, we should mention that a dog breed 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.

The most important factor to consider is how compatible a dog breed`s overall temperament is with your lifestyle.

Is the Norfolk Terrier Smarter than a Cat?

Intelligece of Norfolk Terrier versus cat

Dogs have more neurons in their brains than cats. In fact, a dog has twice the number of brain neurons of a cat (500 million versus 250 million neurons).

This is according to a research study in which the scientist counted the number of brain neurons in dogs and in cats.

Brain neurons are used for processing information. Hence, it is likely that the Norfolk Terrier will have a better information processing power than a cat

Thus, if we are to use the number of neurons in an animal`s brain as a measure of intelligence, then the Norfolk Terrier is definitely way smarter than a cat because the Norfolk Terrier has twice as many brain neurons as a cat.

However, intelligence is a very complex concept that may not be explained simply by how many neurons an animal`s brain has. Learn more here.

What is the IQ of the Norfolk Terrier?

The IQ of the Norfolk Terrier versus human

Before discussing the Intelligence Quotient (IQ) of the Norfolk Terrier, let us first define what Intelligence Quotient (IQ) is. IQ is simply a measure of how mentally advanced a person is relative to that person`s chronological age (the typical age that is calculated from birthday).

For example, a 2-year-old child with the mental capacity of a 4-year-old has an IQ of 200 (that is 4 divided by 2, multiplied by 100).

This is an old but simple definition of IQ.

According to Prof. Stanley Coren, a dog has the mental capacity of a 2-year-old human child.

Let us assume that Norfolk Terriers become full-grown and reach mental maturity at the age of one year.

Also, let us make the bold assumption that, as Norfolk Terriers get older, they do not get significantly smarter than a 2-year-old human child (You Can`t Teach an Old Dog New Tricks).

Thus, a one-year-old Norfolk Terrier will have the mental capacity of a 2-year-old human child, and a 2-year-old Norfolk Terrier will still have the mental capacity of a 2-year-old human child, and a 3-year-old Norfolk Terrier will have the mental capacity of a 2-year-old human child, and so on.

Then, from the way IQ is defined, a one-year-old Norfolk Terrier, which will have the mental capacity of a 2-year-old child, has an IQ of 200! This is not too surprising because Norfolk Terriers mature and age faster than humans.

A one-year-old Norfolk Terrier is twice as smart as a one-year-old human child.

Also, since a 2-year-old Norfolk Terrier will have the intelligence of a two-year-old human, then the corresponding IQ of a 2-year-old Norfolk Terrier is 100. Similarly, a three-year-old Norfolk Terrier will still have the mental capacity of a two-year-old human, making its IQ 66, and so on.

These may sound odd. But this is because the concept of IQ was designed to test human intelligence and not Norfolk Terrier intelligence. That is what you get when you use human intelligence as a reference to measure Norfolk Terrier intelligence.
