Side-by-Side IQ Profile: Shih Tzu vs. Brittany
The Cosmic Pet Pet IQ Lab employs a five-dimensional framework to assess canine intelligence, providing a nuanced understanding beyond simple obedience. For the Shih Tzu, a Toy group dog with a Coren rank of #70, its profile includes Problem Solving 3/5, Training Speed 2/5, Social Intelligence 5/5, Instinctive Drive 2/5, and Memory 3/5. This suggests a dog that is moderately adept at figuring things out, learns new tasks at a slower pace, but possesses exceptional social awareness, with a low intrinsic motivation for traditional dog work and an average capacity for recall.
In contrast, the Brittany, a Sporting group dog with a Coren rank of #19, presents a different cognitive landscape. Its IQ profile features Problem Solving 4/5, Training Speed 4/5, Social Intelligence 3/5, Instinctive Drive 3/5, and Memory 5/5. This indicates a breed with a strong aptitude for critical thinking, a quick grasp of new commands, and a moderate understanding of social cues. The Brittany also exhibits a noticeable, ingrained drive, often tied to its heritage, and an outstanding ability to remember past experiences and learned behaviors.
Where the Shih Tzu Wins Cognitively
The Shih Tzu truly shines in the realm of social intelligence, scoring a perfect 5 out of 5, a clear advantage over the Brittany's 3/5. This elevated capacity means a Shih Tzu is exceptionally adept at interpreting human emotions, subtle body language, and vocal inflections. They often display a profound ability to integrate into family dynamics, sensing mood shifts and adjusting their demeanor accordingly, making them highly empathetic companions. Their keen social awareness allows them to form exceptionally strong bonds and understand complex household routines, often anticipating needs or responding to unspoken cues with remarkable accuracy. This cognitive strength underpins their companionship qualities, allowing them to navigate intricate social environments with grace and sensitivity, making them masters of emotional connection within a household.
Where the Brittany Wins Cognitively
The Brittany demonstrates clear cognitive strengths across several dimensions, notably in problem-solving, training speed, and memory. With a problem-solving score of 4/5, the Brittany exhibits a robust capacity to analyze novel situations and devise effective solutions, often showing ingenuity in overcoming obstacles. This contrasts with the Shih Tzu's 3/5, indicating a more proactive and analytical approach to challenges. Their training speed, also at 4/5, means they typically absorb new commands and behaviors with impressive rapidity, requiring fewer repetitions than the Shih Tzu's 2/5. This swift learning curve makes them highly receptive to advanced training and complex tasks.
Furthermore, the Brittany's memory score of 5/5 is particularly outstanding, far surpassing the Shih Tzu's 3/5. This superior recall allows them to retain a vast repertoire of commands, remember past experiences vividly, and perform intricate sequences of actions consistently over time. This cognitive architecture equips the Brittany for sustained, complex learning and performance, making them adept partners in various dog sports and activities that demand both physical and mental precision.
Which is Easier to Train and Why
When evaluating ease of training, the Brittany generally presents a more straightforward experience due to its higher scores in both training speed and problem-solving. A Brittany's 4/5 training speed indicates a rapid assimilation of new commands, meaning owners often see quick progress with consistent instruction. Their 4/5 problem-solving ability also means they can more readily generalize learned behaviors to new contexts and adapt to novel training scenarios, often figuring out what's expected with less explicit guidance. This breed typically thrives on structured learning and mental engagement, making them eager participants in training sessions and quick to grasp new concepts.
In contrast, the Shih Tzu, with a training speed of 2/5, may require more patience and repetition to solidify new behaviors. While they possess high social intelligence, their lower instinctive drive (2/5) means they might not always be intrinsically motivated by traditional task-oriented training. Owners might find that a Shih Tzu's training benefits from positive reinforcement methods that leverage their social bond, focusing on short, engaging sessions to maintain attention rather than expecting rapid, complex skill acquisition. Their training journey often emphasizes building a strong relationship over quick mastery of numerous commands.
Suitability for Active vs. Relaxed Owners
The distinct cognitive profiles of the Shih Tzu and Brittany naturally align with different owner lifestyles. The Brittany, with its moderate instinctive drive (3/5), exceptional memory (5/5), and strong problem-solving skills (4/5), is inherently suited for active owners. This breed thrives on regular physical exercise, mental stimulation, and purpose-driven activities like scent work, agility, or retrieving games. An owner who enjoys hiking, running, or participating in dog sports will find a Brittany to be an eager and capable partner, whose cognitive strengths allow them to excel in dynamic environments. Their need for engagement means they will not be content with merely lounging; they require opportunities to utilize their intelligence and physical capabilities daily.
Conversely, the Shih Tzu, with its lower instinctive drive (2/5) and profound social intelligence (5/5), is an ideal match for more relaxed owners. While they enjoy moderate daily walks and playtime, their primary need is for companionship and social interaction. Their cognitive strengths are best utilized in a home environment where they can be close to their family, offering comfort and receiving affection. They adapt well to apartment living and prefer a predictable routine, making them excellent companions for individuals or families seeking a devoted, less demanding presence who value emotional connection above athletic prowess.
The Verdict
If your ideal companion is a devoted, empathetic presence that thrives on close social bonds and a more relaxed pace of life, the socially astute Shih Tzu will undoubtedly enrich your home, offering comfort and connection.
If you are an active individual or family seeking a partner for sports, outdoor adventures, and advanced training, the mentally agile and physically capable Brittany will be a fulfilling choice, eager for challenges and consistent engagement.

Are Shih Tzus difficult to train?
While Shih Tzus have a moderate training speed score of 2/5, indicating they may take more repetitions to learn new commands, they are not inherently difficult. Success often comes from patient, positive reinforcement, leveraging their strong social intelligence to build a cooperative bond. Short, engaging sessions focused on consistency yield the best results.
Do Brittanys need a lot of mental stimulation?
Absolutely. With high scores in problem-solving (4/5) and memory (5/5), Brittanys require significant mental engagement to prevent boredom and destructive behaviors. Daily opportunities for training, puzzle toys, and activities that challenge their cognitive abilities are crucial for their well-being and overall contentment.
How do their Coren ranks reflect their overall IQ?
The Coren rank broadly reflects 'working and obedience intelligence,' which aligns with a dog's ability to learn and execute commands. The Brittany's rank of #19 suggests a high capacity for understanding and performing tasks, while the Shih Tzu's rank of #70 indicates they may require more effort and time to master complex obedience tasks, reflecting their distinct cognitive strengths.
