How Smart is the Jack Russell Terrier?
The Jack Russell Terrier is a dog breed that is known to be:
- Alert
- Cheerful
- Courageous
- Energetic
- Independent
But, how smart is the Jack Russell Terrier really?
The Jack Russell Terrier is the 46th smartest dog when it comes to obedience and working intelligence.
Accordingly, compared to other dogs, the Jack Russell Terrier belongs to the `Average Working/Obedience Intelligence Dogs` category.
Jack Russell Terriers tend to learn new commands after 25 to 40 repetitions.
These facts on Jack Russell 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 Jack Russell Terrier is the 46th smartest dog breed.
Furthermore, Coren placed dog breeds into one of six intelligence categories:
- Brightest Dogs: Tend To Learn New Commands After Fewer Than 5 Repetitions
- Excellent Working Dogs: Tend To Learn New Commands After 5 To 15 Repetitions
- Above Average Working Dogs: Tend To Learn New Commands After 15 To 25 Repetitions
- Average Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 25 To 40 Repetitions
- Fair Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 40 To 80 Repetitions!
- Lowest Degree of Working/Obedience Intelligence Dogs: Tend To Learn New Commands After 80 To 100 Repetitions Or More!
The Jack Russell Terrier belongs to the `Average 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.
See the intelligence ranking of a few selected dog breeds in the table below: (note, although 133 dog breeds were studied, there are 79 positions because some breeds tied for the same position)

Jack Russell Terrier Intelligence. A Second Opinion
We reviewed another research study to find out more about the intelligence of the Jack Russell Terrier. This other study is The Canine Behavioral Assessment & Research Questionnaire (C-BARQ) study.
This study was done by research veterinarians from the University of Pennsylvania.
In the study, the researchers asked owners of different dog breeds, including owners of the Jack Russell Terrier to describe how trainable their dogs are.
147 Jack Russell Terrier owners were asked to describe
how easy it was to train their Jack Russell Terrier in the CBARQ research survey.We analyzed what these Jack Russell Terrier owners said about the trainability of their Jack Russell Terriers and compared that to what other owners said about other dog breeds (125 other breeds).
Dogs that are easy to train are always very eager to listen to their owner. These dogs are not stubborn. These dogs obey simple commands, and they learn very quickly.
Also, dogs that are easy to train tend to do well at fetching objects when asked to. Furthermore, this category of dogs also responds positively to correction and ignores distraction.
According to the results from the CBARQ research, Jack Russell Terriers are a little bit easy to train.
In fact, the Jack Russell Terrier ranks 74th out of 124 dog breeds for easiness to train.
Based on our further analysis of the CBARQ research data, we found that the Jack Russell Terrier has a trainability score of 60.9 %.
Other dog breeds that are a little bit easy to train just like the Jack Russell Terrier are listed in the table below:
| Trainability Rank | Breed | Trainability Score |
|---|---|---|
| 71 | Boston Terrier | 62.1 % |
| 72 | Chinese Shar-Pei | 61.9 % |
| 73 | English Setter | 61.3 % |
| 74 | Jack Russell Terrier | 60.9 % |
| 75 | Alaskan Malamute | 60.6 % |
| 76 | Italian Greyhound | 60.6 % |
| 77 | Samoyed | 60.4 % |
According to the CBARQ research data, the dog breeds that are most easy to train are the:
According to the CBARQ research data, the dog breeds that are most difficult to train are the:
However, it is important to note that trainability does not always equal intelligence.
This is because a dog can be smart and stubborn at the same time. A smart but stubborn dog will be hard to train.

The Three Parts of the Intelligence of the Jack Russell 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:
- 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.
- 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.
- 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
You can tell what type of instinctive intelligence a dog breed will have based on the dog group the dog belongs.
The Jack Russell Terrier belongs to the Terrier Dogs group.
Dogs in the Terrier Dogs group, like the Jack Russell 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..
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 Jack Russell Terrier Smarter than a 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 Jack Russell 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 Jack Russell Terrier is definitely way smarter than a cat because the Jack Russell 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 Jack Russell Terrier?
Before discussing the Intelligence Quotient (IQ) of the Jack Russell 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 Jack Russell Terriers become full-grown and reach mental maturity at one year of age.
Also, let us make the bold assumption that, as Jack Russell 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 Jack Russell Terrier will have the mental capacity of a 2-year-old human child, and a 2-year-old Jack Russell Terrier will still have the mental capacity of a 2-year-old human child, and a 3-year-old Jack Russell 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 Jack Russell Terrier, which will have the mental capacity of a 2-year-old child, has an IQ of 200! This is not too surprising because Jack Russell Terriers mature and age faster than humans.
A one-year-old Jack Russell Terrier is twice as smart as a one-year-old human child.
Also, since a 2-year-old Jack Russell Terrier will have the intelligence of a two-year-old human, then the corresponding IQ of a 2-year-old Jack Russell Terrier is 100. Similarly, a three-year-old Jack Russell 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 Jack Russell Terrier intelligence. That is what you get when you use human intelligence as a reference to measure Jack Russell Terrier intelligence.
