How is it that dogs and wolves are still the same species? How much more do dogs need to change before they become a different species?

Dogs and wolves *are* separate species, *Canis lupus* and *Canis familiaris*. There are many species of animals that can still interbreed but are still classified as separate species due to physical, behavioral, or temporal barriers that make it extremely unlikely for the animals to hybridize. Dogs and wolves are more physically distinct than some, so it seems more surprising.
