It's a well-known fact that different dog breeds have different traits, usually connected with the purpose for which humans developed that particular breed. Labradors are friendly and like to carry things. Terriers like to dig and many also like to terrify small furry creatures. Border Collies are very intelligent, herd everything, and need 4 hours of walks a day to stop them doing a wall of death around the living room.
I write that last sentence with a wry smile (and in the case of the last part, a chunk of mildly sarcastic exaggeration) as I look at my own Border Collie Finn, who flatly refuses to set a paw outside the door if it's raining and is usually found upside down and snoring. He is indeed very bright, will herd a football if kicked to one side of him and, while he enjoys his walks, isn't overly fussed how long he's walked for, so long as he gets a few minutes of sniffing time.
