While all domesticated dogs are the same species (Canis familiaris), a wide variety of dog breeds exist because of human-driven selective breeding over the past few hundred years. These breeds are distinct groups created by humans for specific tasks and appearances, not natural evolutionary processes

Wolves have larger brains than dogs because animals with smaller brains tend to be more docile than animals with larger brains. Human brain size has actually decreased over time since humans domesticated ourselves.
Which is ironic considering that racists would say that black people are less civilized and more violent therefore they must be biologically less intelligent when uncivilized humans had larger brains than civilized humans and violence is actually a sign of higher intelligence.
