It's difficult to say exactly which dog breeds are the smartest as there are so many things that need to be consider. Over the years some studies have looked at which breeds are likely to be the most intelligent. Stanley Coren, a well known canine expert and neuropsychologist thinks that trainability is an accurate indicator of intelligence. He assessed 110 breeds and worked with 200 dog obedience judges. These judges scored each of the dog breeds on obedience and these are the five breeds that scored the highest.
Border Collie
Border Collies live to work. They aren't happy if they don't have a job to do and respond very well to training. That's why they thrive as sheep dogs herding sheep all day long. They have long been considered an extremely intelligent breed. However, the fact they are very trainable doesn't make them suitable for everyone. Collies need a huge amount of mental stimulation and can develop behavioural issues if they aren't given enough to do.
Poodle
Poodles often get underestimated but they are actually one of the smartest dogs you can get. They respond very well to training and do well in obedience competitions. They might look pretty but they still love to get outside and exercise. They are keen to learn and make great family pets because they are so good with children. However, Poodles do require a substantial amount of grooming.
German Shepherd
German Shepherd's were originally bred for herding but these days they are best known for being security dogs. They are used by the police and the military for security purposes. They need experienced owners who can give them adequate training as they can be very strong. Despite their reputation for being fierce they can make loving family dogs.
Golden Retriever
Golden Retrievers are an extremely popular dog breed. Due to their high trainability and intelligence they are often used as Guide Dogs for the blind. They are very loyal family dogs that are very easy to train. They need a lot of exercise and should be kept busy as they have a lot of energy to burn off. They are very bouncy, friendly and playful.
Doberman Pinscher
Another well known guard dog has made it into the top 5. The Doberman is a fearless guard dog that many owners use to protect their property. They are sometimes called 'the dog with the human brain'. They are obedient, loyal and very protective of their family. Dobermans may look quite terrifying but they can be very loving and devoted to their owners.
