The amount of genetic mutation that would be required for a dog to give birth to offspring that - in a single generation - was genetically distinct enough to be classified as a separate species from it's mother is, in practice, prohibitively impossible. A fetus with that degree of damage to its DNA won't get past the earliest stages of development.

Lupine and canine are classified as distinct species because in a natural environment they will not choose to breed. Whether they are capable of it or not is something I'm not sure I really want to think about.
