Side-by-Side IQ Profile
A robust Working breed, the Dogue de Bordeaux registers a balanced 3/5 across all five IQ dimensions. Their Problem Solving at 3/5 suggests a moderate capacity for navigating novel situations, often leaning into their protective instincts to assess their environment. Training Speed, also at 3/5, indicates they absorb new commands at an average pace, requiring consistent, clear instruction. Social Intelligence at 3/5 points to a decent understanding of human cues and household dynamics, often expressed through their watchful nature. Their Instinctive Drive, rated 3/5, is largely channeled into guarding and territorial awareness, reflecting their heritage. Finally, a Memory score of 3/5 means they retain learned experiences and commands reliably over time.
Hailing from the Sporting group, the Sussex Spaniel mirrors the Dogue de Bordeaux with a consistent 3/5 across all cognitive metrics, yet their application differs due to their breed purpose. Their Problem Solving at 3/5 often manifests in their methodical approach to scent trails or navigating dense undergrowth during a hunt. A Training Speed of 3/5 indicates they learn new tasks at an average rate, often motivated by engagement and reward. Social Intelligence, at 3/5, reflects their cooperative nature with handlers and their general amiability within a family setting. Their Instinctive Drive, also 3/5, is predominantly expressed through their strong prey drive and desire for flushing and retrieving. A Memory score of 3/5 ensures they recall learned behaviors and hunting patterns effectively.
Where Dogue de Bordeaux Wins Cognitively
Despite the numerical parity, the Dogue de Bordeaux's cognitive strengths often shine in scenarios demanding a discerning, independent assessment of their environment. Their 3/5 Problem Solving, for instance, is less about mastering complex puzzles and more about evaluating potential threats or changes within their perceived territory, exhibiting a calm, watchful deliberation. They might display a nuanced understanding of social hierarchies within the home, using their 3/5 Social Intelligence to gauge who belongs and who doesn't, or to subtly communicate their needs with a deep gaze rather than overt gestures. This social awareness extends to their capacity to discern intent, making them excellent judges of character, even if their reactions are slow and measured. Their 3/5 Instinctive Drive for protection means they excel at being watchful guardians, applying their memory to recall patterns and individuals, making them adept at recognizing anomalies or deviations from routine. This isn't about rapid obedience to every command, but a thoughtful, often slow-burn cognitive process that prioritizes observation and deliberate action, allowing them to make well-considered decisions in their role as a family protector. An owner might observe their Dogue de Bordeaux deliberating over a new sound outside, processing its implications before reacting, a testament to their measured problem-solving and social awareness in a protective context.
Where Sussex Spaniel Wins Cognitively
The Sussex Spaniel, while sharing identical IQ scores, applies its cognitive abilities with a distinct sporting flair. Their 3/5 Problem Solving often manifests as a persistent, methodical approach to tasks involving scent or navigation in challenging terrain. Unlike the Dogue's deliberate assessment, the Sussex might exhibit a focused tenacity in figuring out how to retrieve a hidden toy or follow a complex scent trail, leveraging their ancestral hunting skills. Their 3/5 Social Intelligence makes them highly attuned to their handler's moods and commands, fostering a cooperative working relationship, often eager to please and follow direction in a way that differs from the Dogue’s more independent social processing. This translates into a readiness to engage and participate in shared activities. The 3/5 Instinctive Drive, rooted in flushing and retrieving, means they excel in activities that tap into these natural inclinations, using their memory to recall successful strategies for locating hidden objects. Their Coren rank of #62, while not top-tier, places them within a group of dogs generally considered capable of understanding new commands with a reasonable number of repetitions, suggesting a consistent, if not lightning-fast, intellectual engagement with training.
Which is Easier to Train and Why
Considering both breeds register a 3/5 in Training Speed, the ease of training becomes less about raw learning pace and more about temperament and motivational drives. The Dogue de Bordeaux, a powerful Working breed, often approaches training with a thoughtful independence. While capable of learning, their substantial size and inherent protective instincts mean that early, consistent socialization and positive reinforcement are paramount to channel their 3/5 social intelligence and moderate instinctive drive constructively. They can be strong-willed, meaning an owner must be patient, firm, and demonstrate clear leadership. Their memory of 3/5 ensures they retain commands, but their deliberate problem-solving might mean they take their time to process and comply, especially if they perceive a command as unnecessary or conflicting with their protective role. Training a Dogue de Bordeaux often requires understanding their motivations and building a strong bond.
The Sussex Spaniel, despite the same 3/5 Training Speed, often presents a different training dynamic. As a Sporting breed, they typically possess a greater eagerness to please their handler and a strong desire to work cooperatively. Their 3/5 instinctive drive, focused on scent and retrieve, can be a powerful motivator in training, making them enthusiastic participants in activities that tap into these urges. However, their spaniel heritage can also mean a stubborn streak or a tendency to get distracted by interesting scents, requiring an owner to maintain engagement and make training sessions exciting and rewarding. Their 3/5 social intelligence helps them tune into human cues, and their memory ensures they recall lessons. While not the quickest study, their consistent effort and cooperative nature, combined with their Coren rank, often make them a more straightforward training companion for owners who appreciate a dog that enjoys working alongside them, provided distractions are managed.
Which Suits Active Owners vs Relaxed Owners
The Dogue de Bordeaux, with its imposing stature and Working group classification, might seem to demand intense activity, but their energy profile is often more moderate than perceived. They require regular, consistent exercise to maintain their muscular physique and mental well-being, but typically prefer power walks, short bursts of play, and ample time to observe their environment rather than continuous high-impact activities. Their 3/5 instinctive drive for protection means they benefit greatly from mental stimulation that engages their discernment and social intelligence, such as supervised 'guarding' duties or puzzle toys. They suit relaxed owners who appreciate a calm, watchful companion and are prepared to provide consistent leadership, early socialization, and structured exercise. They are content with a comfortable home environment where they can be part of the family, often preferring to lounge near their people, yet always aware of their surroundings.
Conversely, the Sussex Spaniel, a Sporting breed, generally requires a more active and engaging lifestyle. While not hyperactive, their 3/5 instinctive drive for scent work and retrieving means they thrive on regular, moderate exercise that allows them to explore and use their nose. Daily long walks, opportunities for off-leash exploration in safe environments, or participation in dog sports like scent work or obedience are ideal. Their 3/5 social intelligence and memory make them responsive and enjoyable companions for owners who enjoy spending active time outdoors. They are well-suited to active owners who appreciate a cheerful, sometimes boisterous, companion and are willing to provide consistent mental and physical outlets for their sporting instincts. A relaxed owner might find the Sussex's need for engagement and exercise more demanding than anticipated, potentially leading to boredom or undesirable behaviors.
The Verdict
Choose the Dogue de Bordeaux if you seek a calm, discerning guardian who offers thoughtful companionship and you are prepared to provide consistent leadership and early socialization to channel their protective instincts.
Opt for the Sussex Spaniel if you desire a cheerful, cooperative companion eager for moderate activity and mental engagement, particularly in scent-based or retrieving tasks, and you value a dog that enjoys working alongside you.

Do Dogue de Bordeaux and Sussex Spaniels have similar temperaments due to their identical IQ scores?
While their core cognitive scores are identical, their temperaments differ significantly due to breed purpose. Dogue de Bordeaux are typically calm, watchful, and protective, while Sussex Spaniels are generally cheerful, eager, and more outwardly spirited, reflecting their working roles.
How does a Coren rank for the Sussex Spaniel (62) compare to the Dogue de Bordeaux (not ranked) if their IQ scores are the same?
Coren ranks primarily assess obedience and working intelligence, reflecting trainability for specific tasks. The Sussex's rank suggests a reliable capacity for understanding commands, while the Dogue's unranked status implies a more independent learning style, not necessarily a lower cognitive ability, but one less geared towards rapid, generalized obedience.
Can a Dogue de Bordeaux excel in scent work like a Sussex Spaniel, or vice versa for guarding?
While individual dogs vary, their instinctive drives differ. A Sussex's 3/5 drive is geared towards scent and retrieve, making them naturally adept. A Dogue's 3/5 drive is focused on protection; while they can learn scent work, it's not their primary instinct, just as a Sussex typically lacks the Dogue's inherent guarding intensity.
