Side-by-Side IQ Profile: Understanding Each Dimension
The Cosmic Pet Pet IQ Lab assesses canine intelligence across five key dimensions, offering a nuanced view beyond simple obedience. Let's explore how the Shih Tzu and Norfolk Terrier stack up.
For the Shih Tzu, a Toy breed, their Coren rank is #70. Their Problem Solving is rated 3/5, indicating an average ability to navigate novel situations or achieve goals, often geared towards comfort or attention. Training Speed stands at 2/5, suggesting they may require more repetition and patience to grasp new commands consistently. Social Intelligence is where the Shih Tzu shines with a perfect 5/5, demonstrating an exceptional capacity to understand human emotions and social cues, making them highly attuned companions. Their Instinctive Drive is 2/5, meaning they possess a lower inclination for traditional working tasks, hunting, or intense exploration. Memory is rated 3/5, indicating they have an average recall for routines and learned associations.
The Norfolk Terrier, a Terrier breed, is not Coren-ranked but presents a balanced cognitive profile. Their Problem Solving is 3/5, similar to the Shih Tzu, but often manifested in overcoming physical obstacles or figuring out how to access interesting areas. Training Speed is 3/5, suggesting they learn new commands at an average pace, responding well to engaging methods. Social Intelligence is 3/5, meaning they are generally sociable but perhaps less acutely focused on human emotional nuances compared to the Shih Tzu. Instinctive Drive is 3/5, reflecting their terrier heritage with a moderate urge to explore, dig, or chase, albeit less intense than some other terrier breeds. Memory is also rated 3/5, providing them with an average capacity for remembering commands and experiences.
Where the Shih Tzu Excels Cognitively
The Shih Tzu's standout cognitive strength lies in their remarkable Social Intelligence, scoring a perfect 5/5. This isn't merely about being friendly; it reflects a sophisticated ability to read and respond to human emotions and social cues. A Shih Tzu can often sense when their owner is upset or happy, adapting their behavior to provide comfort or share in joy. This acute social awareness allows them to form deep, empathetic bonds and makes them exceptionally intuitive companions who understand the subtle dynamics of human households.
While their Problem Solving score is 3/5, the Shih Tzu often applies this capacity specifically to social situations. They might 'figure out' how to get extra attention, secure a prime spot on the sofa, or subtly manipulate their owner into providing a treat, all through clever social maneuvering rather than complex physical tasks. This cognitive strength makes them masters of companionship, excelling in roles where emotional connection is paramount.
Where the Norfolk Terrier Excels Cognitively
The Norfolk Terrier's cognitive advantages manifest in their more balanced and task-oriented profile. Their Training Speed of 3/5 surpasses the Shih Tzu's 2/5, indicating they are generally quicker to pick up new commands and routines with consistent positive reinforcement. This means an owner might see results in obedience training more readily, making the learning process feel more dynamic.
Additionally, their Instinctive Drive of 3/5, while moderate, provides a valuable cognitive resource. This drive translates into a persistent curiosity and a desire to engage with their environment, often leading them to explore and investigate. While a Shih Tzu's problem-solving might be socially motivated, a Norfolk Terrier's 3/5 Problem Solving score often applies to navigating physical challenges, like finding a hidden toy or figuring out how to get past a minor barrier. This tenacity and engagement with their surroundings offer a different kind of cognitive richness, making them adept at activities that involve exploration and discovery.
Which is Easier to Train and Why?
When considering ease of training, the Norfolk Terrier generally holds an advantage due to its higher Training Speed (3/5) and moderate Instinctive Drive (3/5). Their terrier nature provides a certain independence but also a drive to engage with tasks, especially when motivated by play or treats. They tend to grasp concepts more quickly and are often eager to participate in structured learning, making them responsive to consistent, positive reinforcement methods. Their problem-solving abilities are frequently applied to understanding how to earn rewards through action.
The Shih Tzu, with a Training Speed of 2/5, typically requires more patience and repetition. Their high Social Intelligence (5/5) means they respond well to praise and emotional connection, but their lower Instinctive Drive (2/5) means they might not always see the inherent 'point' of a task if it doesn't directly lead to comfort or social interaction. They can be prone to stubbornness if they perceive training as tedious or uncomfortable, often using their problem-solving skills to avoid unwanted commands or to get attention through less compliant behaviors. Training a Shih Tzu relies heavily on making the process enjoyable and reinforcing their desire for social approval, rather than relying on a strong innate drive to perform tasks.
Which Suits Active Owners vs. Relaxed Owners?
For owners with a more relaxed lifestyle, the Shih Tzu is often an ideal match. Their exceptional Social Intelligence and lower Instinctive Drive mean they thrive on close companionship, gentle play, and being an integral part of the family's daily routine without requiring extensive physical or mental exertion. They are content with indoor activities, short walks, and plenty of lap time, valuing emotional connection and comfort above rigorous activity. Their cognitive strengths are best appreciated in a home where their ability to provide intuitive companionship is prioritized.
Conversely, the Norfolk Terrier is better suited for owners who appreciate a more active and engaging companion. Their balanced cognitive profile, including a moderate Instinctive Drive and Problem Solving capacity, means they enjoy varied activities, exploration, and consistent mental stimulation. While not needing extreme endurance, they benefit from regular walks, puzzle toys, and opportunities to sniff and investigate their surroundings. Owners who enjoy teaching new tricks, engaging in moderate outdoor adventures, or providing a 'job' for their dog will find the Norfolk Terrier's spirited curiosity and steady learning pace a rewarding fit.
The Verdict
Choose a Shih Tzu if you prioritize an exceptionally socially intelligent companion who excels at emotional connection and thrives in a relaxed, comfort-oriented home environment.
Opt for a Norfolk Terrier if you seek a spirited, curious dog that learns steadily and enjoys engaging in moderate activities and exploration alongside a more active owner.

Do Shih Tzus respond well to obedience training despite their lower training speed?
Yes, Shih Tzus can certainly learn obedience commands, but it requires more patience and consistency due to their 2/5 training speed. Leveraging their 5/5 social intelligence by using positive reinforcement, praise, and making training feel like an enjoyable social interaction is key to their success.
How does the Norfolk Terrier's instinctive drive manifest in daily life?
The Norfolk Terrier's 3/5 instinctive drive typically manifests as a natural curiosity, a desire to explore, and a moderate inclination to dig or chase small critters. This means they enjoy varied environments, benefit from secure outdoor spaces, and can be engaged with scent games or puzzle toys that satisfy their investigative urges.
Are Norfolk Terriers good with children due to their social intelligence score?
With a social intelligence score of 3/5, Norfolk Terriers are generally sociable but may not possess the same intuitive understanding of subtle social cues as a Shih Tzu. They can be good with children, especially if raised with them, but supervision is always recommended to ensure respectful interactions from both sides, as their independent streak might mean they prefer not to be constantly handled.
