Shouldn’t all arguments against evolution be put down since dogs exist?

I mean we literally evolved dogs from wolves in just a few thousand years and im sure a good chunk of that evolution wasn’t even on purpose, just wolves eating our food and getting used to us. If dogs can evolve into all these different shapes and sizes in such a short time (albeit with human assistance) why cant something like a whale go from a 4 legged land baring mammal to you know, a whale in a couple hundred million years with no human assistance?
