Side-by-Side IQ Profile: Westie vs. Kerry Blue Terrier
The Cosmic Pet Pet IQ Lab assesses canine intelligence across five key dimensions. For the West Highland White Terrier, ranked #47 by Coren, and the Kerry Blue Terrier, which is not Coren-ranked, these metrics provide a detailed comparative view.
The Westie's cognitive breakdown includes: Problem Solving (3/5), where they approach challenges with an independent, practical mindset, often figuring out solutions to environmental puzzles like retrieving a toy. Training Speed (3/5), indicating they learn commands at a moderate pace, thriving with consistent, positive reinforcement. Social Intelligence (3/5), showing they gauge human moods well and form strong bonds, though their independence can be misinterpreted. Instinctive Drive (3/5), true to their heritage, involves a moderate prey drive and enjoyment of digging. Memory (4/5), a strong cognitive asset, means they retain learned behaviors and routines for extended periods, contributing to consistent performance and environmental understanding.
The Kerry Blue Terrier's cognitive profile features: Problem Solving (3/5), where they tackle problems with characteristic terrier tenacity, often employing persistence to achieve goals. Training Speed (3/5), meaning they grasp new concepts at a respectable rate with focused instruction, enjoying the learning process. Social Intelligence (3/5), indicating they are perceptive of human emotions, showing loyalty and adapting to family dynamics, though they may be reserved with strangers. Instinctive Drive (3/5), reflecting their history as versatile farm dogs with a significant prey drive and desire for purpose. Memory (3/5), a reliable trait for recalling commands and experiences, though not their most dominant cognitive feature, suggesting occasional refreshers can be beneficial.
Where the West Highland White Terrier Wins Cognitively
The West Highland White Terrier's cognitive advantage shines most brightly in the domain of memory, scoring a 4/5 compared to the Kerry Blue's 3/5. This enhanced recall means a Westie is more likely to retain learned behaviors, house rules, and even specific positive or negative associations over longer periods without needing frequent refreshers. For an owner, this translates into a more consistent application of training, as commands taught months ago can often be executed with the same precision as those learned last week. Their superior memory also aids in navigating their environment, remembering preferred routes, safe spots, and where exciting things might be found. This robust memory contributes to their overall adaptability, allowing them to build a comprehensive mental map of their world and react to situations based on a rich bank of past experiences.
Where the Kerry Blue Terrier Wins Cognitively
While the provided IQ metrics show identical scores in problem-solving, training speed, social intelligence, and instinctive drive, the Kerry Blue Terrier's overall cognitive profile, particularly when considering their working background, suggests a robust mental engagement focused on application. Though their memory score is slightly lower than the Westie's, the Kerry Blue's balanced instinctive drive (3/5) combined with their problem-solving tenacity (3/5) often translates into a deep-seated desire for purpose and sustained activity. They excel in tasks requiring both physical and mental application, such as agility or scent work, demonstrating a practical intelligence rooted in their heritage. Their cognitive strengths lie in their ability to apply their intellect actively and persistently to real-world challenges.
Which Is Easier to Train and Why
When considering ease of training, both breeds score a 3/5 for Training Speed, indicating a moderate learning pace. However, the Westie's superior memory (4/5) gives it a distinct advantage in the long run. While a Kerry Blue might grasp a new command just as quickly initially, the Westie is more likely to retain that command over time without needing as much reinforcement. This means less 're-training' and more consistent performance for the Westie.
For example, teaching a 'stay' command might take similar effort for both breeds in the first few sessions. But after a month without practice, the Westie is more likely to remember and execute the 'stay' perfectly, whereas the Kerry Blue might benefit from a quick refresher. Both breeds exhibit a characteristic terrier independence, meaning training must be engaging, positive, and consistent to overcome their strong-willed nature. Neither is a 'push-button' dog; effective training for both relies on understanding their motivations – for the Westie, leveraging their memory for consistent recall, and for the Kerry Blue, channeling their instinctive drive into purposeful activities.
Which Suits Active Owners vs. Relaxed Owners
The choice between a Westie and a Kerry Blue based on owner activity levels hinges on how their similar instinctive drives and problem-solving abilities manifest. The West Highland White Terrier, with its 3/5 instinctive drive, thrives with owners who can provide consistent mental stimulation and moderate physical activity. They enjoy daily walks, puzzle toys, and interactive play that taps into their problem-solving skills. While they appreciate a good romp, they are also content with relaxed evenings curled up, provided their daily needs are met. Their moderate social intelligence means they adapt well to various household dynamics. They suit owners who enjoy engaging with their dog's curious mind and spirited personality, offering both structured activities and quiet companionship.
The Kerry Blue Terrier, also scoring 3/5 in instinctive drive, demands a more robust outlet for its energy and working heritage. While numerically similar to the Westie, the Kerry Blue's historical roles as a versatile farm dog and hunter mean their drive often expresses itself with greater intensity and physical demand. They are better suited for active owners who are keen on dog sports like agility, obedience, or even advanced tracking. Their problem-solving (3/5) and training speed (3/5) mean they excel when given a 'job' to do, thriving on challenges that engage both their physical prowess and mental acuity. A relaxed owner might find a Kerry Blue's energy and need for engagement overwhelming, potentially leading to boredom-induced behaviors. For the owner who enjoys an active lifestyle and wants a canine partner for adventures and structured activities, the Kerry Blue is a compelling match.
The Verdict
Choose a West Highland White Terrier if you value a robust memory for consistent training retention and prefer a spirited companion who enjoys both active engagement and relaxed home life, provided their cognitive and physical needs are met daily.
Opt for a Kerry Blue Terrier if you lead an active lifestyle, are prepared to channel a strong working drive into structured activities like dog sports, and appreciate a tenacious, intelligent partner for dynamic challenges.

Are West Highland White Terriers good with children?
Westies, with their 3/5 social intelligence, can be good with older, respectful children who understand how to interact gently with dogs. Their independent and sometimes feisty terrier nature means close supervision is crucial with very young children to prevent accidental nips if they feel cornered or teased. Early socialization helps them develop appropriate boundaries.
Do Kerry Blue Terriers require a lot of grooming?
Yes, Kerry Blue Terriers have a distinctive soft, wavy, non-shedding coat that requires significant grooming. Regular brushing, at least a few times a week, is essential to prevent matting, and professional stripping or clipping every 6-8 weeks is necessary to maintain their coat's health and appearance. This commitment is part of owning a Kerry Blue.
Which breed is more prone to barking?
Both West Highland White Terriers and Kerry Blue Terriers, being terriers, can be prone to barking due to their alert nature and instinctive drive (3/5 for both). Westies might bark more at novel sights or sounds in their immediate environment, while Kerry Blues may bark more in response to perceived threats or as a way to express their energy and desire for engagement. Consistent training from a young age can help manage this trait in both breeds.
