Are Jack Russell Terriers Smart?

Jack Russell Terriers are smart dogs. They are agile and learn new tricks fast. Jackies have an average intelligence in terms of obedience. Their ability to perform the tasks they were bred for is high. They easily understand what humans want from them.

Owners perceive dogs’ intelligence as equivalent to that of 3- to 5-year-old kids. This is suggested by a study[1] meant to assess how dog owners perceive dogs’ cognitive abilities.

It is difficult for scientists to compare the intelligence of different dog breeds. Each breed excels in some areas where others do not. 

There are also different types of intelligence observed in dogs.

The following table illustrates how Jack Russells score in various types of intelligence.

How To Measure The Intelligence of Jack Russell Terriers

You can measure the intelligence of your Jack Russell Terrier by engaging them in activities and observing how they react. The time it takes them to solve tasks reveal their intelligence. 

These activities measure your dog’s ability to:

  • Solve puzzles
  • Identify your emotions
  • Distinguish between different food quantities
  • Obey commands

and more.

Professionals use various factors to assess dog cognition abilities. These factors are measurable. You can apply tests to identify how your Jack Russell approaches various situations related to these factors.

In a study[2] made on canine cognition, the factors measured were divided into two categories, as follows:

1. Factors that measure non-social cognition:

  • Discrimination learning
  • Object permanence
  • Object manipulation
  • Object learning
  • Categorization
  • Memory
  • Spatial cognition
  • Quantitative understanding

2. Factors that measure social cognition:

  • Social learning
  • Dog-to-human communication
  • Perspective-taking
  • Response to human cues

Jack Russell Terrier Intelligence Test Examples

Canine cognitive abilities are quick to measure.The structure of dog’s cognitive abilities is similar to humans’.[3] 

You can determine if your Jack Russell is intelligent by applying various tests. These tests are easy to apply and do not require professional assistance. 

Your Jack Russell is smart if they are able to perform the following tasks:

  • They respond to commands without practice.
  • They can see when you are sad and try to make you feel better.
  • They know you are leaving by recognizing your body language.
  • They escape easily if they are enclosed.
  • They know how to remain safe when exposed to danger.
  • They solve puzzles quickly.

Assess Jack Russell’s Ability to Pass A Barriere for A Treat

Place an obstacle in front of your dog’s food bowl. Bring them to the obstacle and let them get to the food bowl by themselves. 

To make it even harder, build a maze that your dog has to pass through to get to the food. Set a timer to measure how long it takes for your dog to reach the food. 

Assessing Your Jack Russell’s Ability To Distinguish Between Big and Small Quantities

Apply this test[4] while your dog has an empty stomach. Place two food plates on the floor. Put more food on one plate than on the other. Your dog will start eating from a plate. When they choose one, remove the other. 

Repeat this 6 times and see how often your dog chooses the larger quantity of food. If your Jack Russell chooses the bowl with a larger amount of food most of the time, they are smart.

Jack Russell Terriers’ Instinctive Intelligence

Jack Russell Terriers’ instinctive intelligence lies in their capacity to hunt vermin. This is a complex action not accessible to many dog breeds. Jack Russells have high instinctive intelligence.

Instinctive intelligence measures a dog’s ability to carry out tasks they were bred to do. These tasks include guarding, fetching, herding, pointing, supplying companionship, and more. 

Jack Russells were bred for hunting for more than 200 years. Their hunting genes are strong. This makes them highly intelligent in terms of instinctive intelligence. 

It is difficult to say whether Jack Russell Terriers are more instinctively intelligent than other breeds.[5] Breeds are used for different taks. This is why they have have different abilities. 

Jack Russell Terrier Adaptive Intelligence

Jack Russells display high levels of adaptive intelligence. They can learn on their own and adapt to new situations. They are also skilled at learning how to benefit from their environment. 

Adaptive intelligence measures a dog’s ability to learn from and adapt to its environment. This refers to what a dog is capable of learning by itself.

Adaptive intelligence often comes down to individual dogs and not the breed. This characteristic differs among individuals of the same breed. It also correlates to environmental factors, socialization levels, or training.[6]

If a Jack Russell terrier has not been socialized as a puppy, its adaptive intelligence will be lower as adults. Dogs that are exposed to different environments adapt easier to new situations. 

Dog owners raise their dogs differently. This makes it hard to say that all Jack Russells have high or low adaptive intelligence levels.

Jack Russell Terrier Emotional Intelligence

Jack Russell terriers display average to high levels of emotional intelligence. They are used to interacting with humans and identifying what humans want from them. 

The emotional intelligence of Jack Russells is related to their individual experiences. Some Jack Russells are more emotionally intelligent than others.  

Emotional intelligence in dogs is difficult to assess. Dogs can not verbalize their feelings. Humans can understand dog emotions only by observing their behavior and body language.  

An easy way to check your Jack Russell’s emotional intelligence is to observe how they react when you are sad or sick. 

Jack Russell Terrier Working and Obedience Intelligence 

Jack Russell Terriers occupy the 84th position in a test assessing working and obedience intelligence. This study[7] evaluated the performance of 130 breeds. Jack Russell Terriers scored average. 

Throughout their breed’s history, Jack Russells had to learn what their owners wanted from them. This included finding and retrieving prey. 

The ability of understanding humans’ demands is encrypted in their genes.

Canine working and obedience intelligence measures dogs’ ability to understand what humans want from them. It also refers to the dog’s willingness to perform the action. 

Working and obedience intelligence is a form of social intelligence. Studies on social intelligence in dogs cover how well dogs understand their rank related to humans. They also observed if dogs can follow human cues.[8] 

The fact that Jack Russells have scored average on this test is a desired quality in dogs. The smartest dogs can identify human intention relatively quickly. This means they are obedient, but they also know what they can get away with.

Highly intelligent dogs in terms of obedience need to learn the limits imposed on them. This requires more energy on your part.

Jack Russell Terrier Brain Size

The brain of a Jack Russell Terrier measures around 4.2[9] cubic inches. It weighs approximately 2.4 ounces[10]. These figures are influenced by the activities a Jack Russell has been exposed to. A Jack Russell’s body size and weight also play a role, as well as their environment. 

The size of a Jack Russell’s brain is highly influenced by genetics. This genetic information is a result of selective breeding. A study conducted in 2019 shows that humans are capable of altering the brains of dogs.[11]

The differences in brain size among breeds are correlated with their behavior. The size of the dog and their skull shape also play a key role. 

Jack Russells were bred for hunting small prey. They have also been used for vermin control for at least one hundred years. This is why their brain size is similar to Boston Terriers. Boston Terriers have also been used for vermin control.

The size of a dog’s brain is not necessarily correlated with all intelligence types. A study[12] on 7000 dogs from 74 breeds suggests brain size does not predict social intelligence levels in dogs.

Are Jack Russell Terriers Easy To Train?

Yes, Jack Russells Terriers are easy to train. They are intelligent and agile. Jack Russell terriers are quick learners. They have a native ability to understand human commands.

Jack Russells were bred for hunting. This means they have an ability to understand what humans want from them. 

They are also used to working with other dogs. This ability is a result of hunting in packs. 

The potential problem training Jack Russels is they are easily distracted. This happens when a small animal or object passes by. Their hunting instinct is what causes this behavior.
