Top Smartest & Dumbest Dogs: IQ Rankings Revealed!

1. Border Collie

Commonly known as the "Border," this large breed is not only striking in appearance but also possesses a natural intelligence that is both sharp and trainable. This has historically made it an excellent choice for a herding dog, hence its name. Beyond its intelligence, the Border Collie is renowned for its gentle and loyal nature, which has contributed to its popularity as a favored breed among dog enthusiasts.

1. Poodle

The Poodle is not just endearing in looks; its intelligence is equally impressive, ranking second in dog intelligence lists. Those who have owned a Poodle know that these dogs are easy to train, highly cooperative, and rarely destructive, making them a delightful choice for any family.

2. German Shepherd

Shepherds, whether used for herding or hunting, are known for their intelligence, a trait that is essential for completing their duties. The German Shepherd is a prime example of this, being both common and beloved in the canine world.

3. Golden Retriever

While a hunting breed, the Golden Retriever is known for its friendly and enthusiastic nature, coupled with intelligence and a charming personality. This makes them an ideal companion for growing families.

4. Doberman Pinscher

Once used both for hunting and herding, the Doberman Pinscher is now often trained as a police or military dog. This versatility, along with its high intelligence, speaks to the breed's adaptability and mental prowess.

5. Shetland Sheepdog (Shetland Collie)

Less common in China, the Shetland Sheepdog is cherished in American households. As a herding dog, this breed boasts high intelligence and a moderate size, making it an excellent choice for a family watchdog.

6. Labrador Retriever

Labradors are quick learners, understanding and remembering commands with ease. Their striking appearance and versatility make them appealing to people of all ages.

7. Pug

The Pug, a less common breed, is a small hunting dog and a popular companion. With its long, straight hair and calm demeanor, the Pug is quiet and rarely barks.

8. Rottweiler

This breed embodies strength, courage, and intelligence, with a high level of agility and a friendly disposition. Despite its intimidating appearance, the Rottweiler is not as common due to its perceived unattractive look.

10. Australian Cattle Dog (Queensland Heeler)

Also known as the Queensland Heeler, this dog is alert and agile but can be cautious, requiring patience during initial training to build trust.

While there are dogs with high intelligence, there are also those with lower IQs. Scientists have observed that the least intelligent dog breeds include the Shih Tzu, Basset Hound, Mastiff/Bulldog, Pekingese, Bloodhound, Russian Shepherd, Tibetan Mastiff, Tibetan Spaniel, Japanese Chin, and Afghan Hound.

For dogs with lower intelligence and larger sizes, it's advisable to reconsider adoption unless you have a strong passion for them and the ability to manage them effectively. Breeds like the Tibetan Mastiff can be prone to accidents if not properly handled, especially in nondogfriendly households.

Some dogs may not obey even when wearing a collar, especially if they are stronger than their handlers. This can lead to potential injuries to themselves or others, so caution is paramount.
