Dogs have no lines of symmetry. They're never completely equal on both sides. No creatures are.
However, in terms of Biology, dogs, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side. Thus, they have a single line of symmetry.
