Why can’t dogs breed with cats?
Cats and dogs cannot mate with each other, even if it looks like they’re trying to do so. Their breeding behaviors, heat cycles, and different DNA prevent them from being able to produce healthy, viable offspring. Hybrid species can be created when the animals have similar DNA to each other, such as lions and tigers.

How did dogs evolve from wolves?
Dogs were probably domesticated by accident, when wolves began trailing ancient hunter-gatherers to snack on their garbage.
