What is the smartes dog bread in world?

It's not possible to definitively say which dog breed is the "smartest" in the world. Intelligence in dogs is complex and can be measured in different ways.

Here's why:

* Different Types of Intelligence: Dogs exhibit different types of intelligence, including:

* Instinctive intelligence: This relates to their natural abilities based on their breed's history (e.g., herding, retrieving).

* Adaptive intelligence: This is their ability to learn and adapt to new situations and environments.

* Obedience intelligence: This refers to their ability to learn and follow commands.

* Training Methods and Individual Differences: A dog's intelligence is also influenced by its training, environment, and individual personality.

* Ranking Systems: Many lists attempt to rank dog breeds based on intelligence, but these are often based on anecdotal evidence and subjective opinions.

Instead of focusing on a single "smartest" breed, it's more helpful to consider:

* What kind of intelligence you're looking for: Do you want a dog that's good at learning tricks, a dog that's independent and resourceful, or a dog that excels at specific tasks?

* Your own training style and experience: Some breeds may be more challenging to train than others.

* Your lifestyle: Choose a breed that fits your activity level and living situation.

Some breeds often mentioned for their intelligence and trainability include:

* Border Collie: Known for their herding instincts and exceptional working intelligence.

* Poodle: Highly intelligent and adaptable, often excelling in obedience and agility.

* German Shepherd: Known for their intelligence, loyalty, and trainability.

* Golden Retriever: Intelligent, eager to please, and often used as guide dogs.

* Doberman Pinscher: Intelligent, athletic, and often used for police work.

Ultimately, the best dog breed for you is the one that fits your individual needs and personality.
