Side-by-Side IQ Profile: Icelandic Sheepdog vs. Kerry Blue Terrier
Despite both breeds scoring 3/5 across the board in the Cosmic Pet Pet IQ Lab, their historical roles mean these cognitive dimensions manifest quite differently.
The **Icelandic Sheepdog**, a herding breed, demonstrates its **Problem Solving (3/5)** by navigating complex terrain to gather and guide livestock, often making independent decisions in varied weather. Their ingenuity is practical and situation-specific, focused on achieving a desired outcome without constant human direction. Their **Training Speed (3/5)** is generally good, as they respond well to positive reinforcement and clear communication, showing willingness to learn. However, their independent herding spirit means they might occasionally prioritize their own assessment over a human directive. For **Social Intelligence (3/5)**, these dogs exhibit a nuanced understanding of social dynamics within their family unit and with livestock, adept at reading human emotions and anticipating flock movements. Their **Instinctive Drive (3/5)** is primarily herding—a powerful urge to gather, bark at, and move animals or even family members, often expressed through watchful vigilance. Finally, their **Memory (3/5)** is robust for routines, learned commands, and territory layout, crucial for navigating open pastures and recalling specific livestock behaviors.
The **Kerry Blue Terrier**, conversely, showcases its **Problem Solving (3/5)** acumen in tasks requiring tenacity and independent thought, such as locating and dispatching vermin. They excel at figuring out how to bypass obstacles or access confined spaces, often employing a clever, trial-and-error approach driven by their strong prey drive. Their **Training Speed (3/5)** sees them learn quickly when motivated, particularly for engaging tasks. However, their independent and sometimes strong-willed terrier nature means they might choose to comply only if they perceive a clear benefit, requiring patience and creativity from handlers. For **Social Intelligence (3/5)**, while deeply devoted to their families, Kerry Blues can be discerning with strangers and may exhibit a confident demeanor towards other dogs. Their social cognition is finely tuned to their immediate human pack, displaying loyalty. Their **Instinctive Drive (3/5)** is rooted in their terrier heritage: a potent prey drive, a desire to dig, and a protective instinct for their territory and family, fueling their determination. Their **Memory (3/5)** is good for commands, routines, and experiences, both positive and negative, contributing to their adaptability and ability to learn complex tasks, especially in performance sports.
Where the Icelandic Sheepdog Wins Cognitively
The Icelandic Sheepdog often demonstrates a cognitive edge in collaborative and environmentally aware problem-solving. Their historical role as a herding dog required them to work in tandem with humans, interpreting subtle cues and making decisions that benefited the entire flock. This translates into a sophisticated understanding of their environment and the ability to anticipate group movements, whether of sheep or family members. Their communication style, often involving barks and body language, is finely tuned for conveying information about their surroundings or warning of potential issues, showcasing a superior ability to read and react to their immediate ecosystem and human partners. This breed excels at tasks requiring a gentle yet firm influence, using their cognitive skills to guide rather than confront.
Where the Kerry Blue Terrier Wins Cognitively
The Kerry Blue Terrier, conversely, exhibits superior cognitive strength in independent problem-solving and tenacious pursuit of a goal. Bred to hunt vermin, they developed a capacity for self-reliance and strategic thinking in challenging situations. This involves assessing a situation, identifying a target, and devising a plan to reach it, often requiring cleverness and persistence. Their ability to focus intensely on a task, blocking out distractions, allows them to overcome obstacles that might deter other breeds. This terrier's cognitive victories are often seen in their determined efforts to retrieve an object, navigate complex agility courses with precision, or outsmart a puzzle toy, showcasing a robust, self-driven intellect geared towards achieving individual objectives.
Which is Easier to Train and Why
When considering ease of training, the Icelandic Sheepdog generally presents a more straightforward path for the average owner. Their herding background instilled a desire to work alongside humans and a natural responsiveness to direction. They are typically eager to please, making them receptive to positive reinforcement and consistent guidance. While they possess an an independent streak characteristic of herding breeds, it usually manifests as thoughtful decision-making rather than outright defiance. Their communication is often clear, and they tend to be forgiving of minor handler errors.
The Kerry Blue Terrier, while equally capable of learning, requires a more experienced and patient trainer. Their terrier tenacity and self-assured nature mean they can be strong-willed and may challenge commands if they don't perceive a clear purpose or benefit. Training a Kerry Blue demands consistency, firm but fair boundaries, and engaging methods that tap into their high prey drive and desire for mental stimulation. Without proper direction, their independence can lead to selective hearing or a tendency to follow their own agenda, making their training journey more of a partnership negotiation than a simple instruction-following exercise.
Which Suits Active Owners vs. Relaxed Owners
The Icelandic Sheepdog is well-suited for active owners who can integrate them into family activities and provide consistent mental engagement. While they enjoy outdoor adventures and daily walks, their energy is often expressed in bursts and through their desire to “herd” their family, rather than sustained, high-intensity exertion. They thrive on having a purpose, whether it's learning new tricks, participating in dog sports like agility or herding trials, or simply being a vigilant companion. A relaxed owner might find their constant need for interaction and vocal alerts challenging, as they are not content to be mere couch potatoes.
The Kerry Blue Terrier, on the other hand, demands a truly active and dedicated owner. Their high energy levels and strong prey drive necessitate rigorous daily exercise, including brisk walks, runs, or engaging play sessions. Beyond physical activity, they require significant mental stimulation to prevent boredom and destructive behaviors. This breed excels with owners who are committed to structured training, dog sports, or other activities that channel their drive and intelligence. A relaxed owner would likely struggle with the Kerry Blue's intensity, potential for mischief, and need for constant engagement, as their spirited nature can quickly become unmanageable without appropriate outlets.
The Verdict
Choose the Icelandic Sheepdog if you seek a communicative, adaptable companion eager to participate in family life and gentle activities, appreciating a dog that works with you.
Opt for the Kerry Blue Terrier if you are an experienced, highly active owner prepared for a spirited, independent partner who thrives on challenging training and vigorous physical and mental engagement.

The Icelandic Sheepdog is known for being quite vocal, using barks to alert and communicate, a remnant of their herding role. Kerry Blue Terriers can also be vocal, particularly when alerting to strangers or during play, but their barking frequency might be more situational than the Icelandic's.
Are these breeds good with children?

Icelandic Sheepdogs are often gentle and patient, sometimes attempting to “herd” children. Kerry Blues are loyal and playful but their spirited nature and potential for exuberance means supervision is always advised, especially with very young children.
Which breed requires more grooming?
The Icelandic Sheepdog has a double coat that requires regular brushing, especially during shedding seasons, to manage loose hair and prevent matting. The Kerry Blue Terrier has a single, non-shedding coat that requires professional grooming every 6-8 weeks, including clipping and stripping, to maintain its distinctive appearance and prevent matting.
