What two animals make up a dog?

This is a bit of a trick question! There's no single answer because dogs are domesticated animals that evolved from wolves.

Here's why it's tricky:

* Evolution: Dogs are descended from wolves, not a combination of two distinct animals.

* Domestication: Through selective breeding over thousands of years, humans changed wolves into the many breeds of dogs we see today.

So, while there are no two animals that directly "make up" a dog, the answer ultimately lies with their ancestor, the wolf.
