How did the different breeds of dogs come to be?
Since dogs are a domesticated animal, you’d have to look at what purpose the dog was used for originally. Most breeds originated as working dogs, doing some job or helping their humans in some way. So the people that bred them chose the breeders with the characteristics they wanted, often from observing them close at hand. If you see some dog herding your sheep in some minor way, you might breed it with another that had similar traits. If you lived in a cold place you would breed the dogs that had thicker coats and were hardier. If you wanted dogs for use in water, you might choose those that had webbed feet and a liking for water. But dogs with thick coats or a love/need for water might not survive in really hot places so they wouldn’t be chosen to breed or simply not live long enough to breed. Now, people breed more specifically to aim at some kind of breed perfection, often for vanity reasons, and not purpose driven. Many times the ones that people choose now are not best for the do
