Which is the brilliant breed in dogs

The retriever may flush out game where the hunter tells it to , and then retrievers after the kill, because it needs to follow commands to do its jobs it ranks higher, but it is not capable of doing the complete on it's own as it does not have the ability to calculate what direction of move a animal is going to move to be able to catch it, so it does not have the same ability as the greyhound to think and calculate but it is more trainable as a result scores higher based on what certain people view as a measure of intelligence.

having brought in and owned and foster greyhounds right from the track it is amazing to see them become housetrained in a day or 2 and watched them figure out how they are supposed to behave inside a house just by observing other dogs in the household, most breeds adult dogs if having never been in home before would take a month of training to get to the same point that a greyhound can figure out on their own in just days.

I owned coonhound that could pick on training at an amazing rate, he knew all his commands in 2 languages, in sign and even spelled out, he even grasped on counting to 10 whether through counting by barking or retrieving a certain number of items, later had to shepherds one was highly trainable but certain things like the counting he could not grasp, the other took a while even to learn simple commands, Yet according to intelligence ratings a coonhound is rated far lower than a shepherd. Other thing is even 2 dogs of the same breed will vary in trainabilty/intelligence
