"It is not a breed," Sulimov explains. "We have reproduced the initial 'pre-breed norm' of a dog, the way it used to be 100,000 years ago. In other words before humans began to 'specialize' it, breeding it for hunting, guarding, etc. Any specialization limits possibilities." I found this fascinating and the "Any specialization limits possibilities" reminds me of that Heinlein quote: "A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."
