He neuropsychologist Stanley Coren carried out a research and classification work based on the capacity and abilities of dogs.
According to the specialist, there is a adaptive intelligence, that allows solving situations, and a instinctive intelligence, which is rather innate. It also talks about spatial, kinesthetic, interpersonal and emotional intelligence.
In his book The intelligence of the dogs, Coren presented the results of a long survey 199 dog obedience judges.
From hereí emerge the 10 most intelligent races, whose ranking is based on speed of learning a new order and in obedience at least 95% of the time:
1- Border collie
2- Poodle
3- German shepherd
4- Golden retriever
