Smart Border Collie or Not?

A BC walks into a butcher shop with a purse strapped around his neck. He walks up to the meat case and calmly sits there until it’s his turn to be waited on. A man, who was already in the butcher shop, finished his purchase and noticed the dog. The butcher leaned over the counter and asked the BC what it wanted today. The dog put its paw on the glass case in front of the ground beef, and the butcher said, How many pounds?" The BC barked twice, so the butcher made a package of two pounds ground beef. He then said, "Anything else?" The dog pointed to the lamb chops, and the butcher said, "How many?" The BC barked four times, and the butcher made up a package of four lamb chops. The dog then walked around behind the counter, so the butcher could get at the purse. The butcher took out the appropriate amount of money and tied two packages of meat around the BC’s neck. The man, who had been watching all of this, decided to follow the dog. It walked for several blocks and then up to a house where it began to scratch the door to be let in. As the owner opened the door, the man said to the owner, "That’s a really smart dog you have there." The owner said, "He's not really all that smart. This is the second time this week he forgot his key."
