Top 5 Least Intelligent Small Dog Breeds in the USA

Talking about a dog’s intelligence can be a sensitive topic among pet owners since nobody enjoys thinking their furry companion is less smart. However, knowing a breed's intelligence based on trusted evaluations allows owners to have sensible expectations for training and care.

The Coren scale, crafted by canine psychology specialist Dr. Stanley Coren, rates dog breeds on their working and obedience intelligence. This scale measures how fast a breed picks up new commands and its ability to follow them correctly the first time. It’s crucial to point out that this intelligence rating primarily assesses trainability and obedience, rather than the overall behavior or affection a dog may show. Also, intelligence isn’t determined by size, with small breeds placing all along the spectrum.

In this article, we’ll look at the five least intelligent small dog breeds in the USA according to the Coren scale. We’ll also offer insights into what this means for training, behavior, and maintaining a joyful relationship with these cherished pets.

5. The Chihuahua

The Chihuahua is the tiniest dog breed worldwide and remains a popular pet choice across the United States. While it ranks low on obedience intelligence—often needing 40 to 80 repetitions to learn a command and obeying on the first try only about 30% of the time—Chihuahuas are known for their deep affection and strong bonds with their owners.

Training Chihuahuas can be challenging due to their stubborn and determined nature, but patient and consistent training approaches tend to yield good results. These dogs are treasured not just for obedience but more for their loving character and adaptability to various lifestyles, including urban apartments found in cities like New York or Chicago.

4. Lhasa Apso

The Lhasa Apso, a dog breed with roots in Tibetan monasteries, ranks similarly low on the Coren scale, requiring numerous repetitions to follow commands effectively. Known for its thick, long coat that demands regular grooming, this breed is often more independent and less focused on obedience than other small dogs.

Pet owners in the USA with busy schedules might find the Lhasa Apso’s grooming needs demanding, yet its devotion and role as a watchdog compensate for the training persistence required.

3. The Shih Tzu

The Shih Tzu continues the trend among less obedient small breeds, ranking low in obedience intelligence, often needing 80 to 100 repetitions to learn commands and obeying immediately only about 25% of the time. Despite its stubborn streak, the Shih Tzu is a beloved companion, especially favored among American families for its friendly companionship.

Effective training for Shih Tzus involves understanding their independent spirit and using rewarding, consistent techniques. Their presence as cuddly lap dogs in many American homes is a testament to their cherished personalities regardless of intelligence rankings.

2. The Basset Hound

The Basset Hound is a low-to-medium sized dog famous in the USA for its keen sense of smell and stubborn nature, making it one of the most challenging breeds to train. Ranking near the bottom of obedience intelligence lists, they typically require many repetitions to grasp commands and follow them predictably.

Basset Hounds thrive when training is lively and consistent, channeling their scent-driven instincts in positive ways. Owners from suburban areas, especially in places like Texas or Florida, appreciate the breed's calm temperament once well-trained.

1. The Pekingese

Claiming the lowest obedience intelligence among small dogs, the Pekingese demands 80 to 100 repetitions before a command is learned and obeyed reliably only about 25% of the time. This breed is adored in the USA for its regal appearance and loving nature.

Though stubborn, Pekingese make devoted companions to owners who embrace their unique personality and approach training patiently. They’re especially popular in urban settings like California cities where their minimal exercise needs suit apartment living.

Understanding Intelligence and Training

It’s essential to understand that the Coren scale assessment centers on obedience and work-related intelligence. Several of these breeds show other forms of smarts, including problem-solving skills and the ability to emotionally connect with humans, which the scale doesn’t capture.

Successful training depends largely on the approach of the owner—patience, consistency, and positive reinforcement remain the key to overcoming perceived obedience challenges. These breeds truly thrive when their personalities and instincts are respected and worked with.

Responsible Ownership and Ethical Considerations

Choosing a dog breed, even those that rank lower in obedience intelligence, should involve selecting reputable breeders or adopting from shelters. Responsible pet ownership includes being aware of breed-specific traits, grooming requirements, health care, and training demands.

Being well-informed leads to fulfilling relationships that appreciate each pet’s unique strengths beyond simple intelligence scores.

Whether you’re currently an owner or thinking of getting one of these breeds, embracing their quirks and qualities with loving patience will build a rich and lasting bond.
