Most of the various sizes and shapes of dogs were achieved via selective breeding by humans. That is if the wanted dogs to be able do go down rabbit burrows, the mated dogs with shorter than average legs, generation after generation until they got a dachshund.
If they wanted a dog to hunt wolves, the bred the biggest and strongest dogs, and got a Wolfhound.

Good answer above. In a word; " artificial selection ". The selection that gave Darwin one of the great inspirations for his theory; the theory of evolution by natural selection.

Mostly by selective artificial breeding, which produces effects in a short period of time that would take much longer to happen in nature, and in many cases would never happen in nature.

because people bred them to look that way. Dogs did not just evolve into all the different breeds there are today, people did it!
