Why do dogs’ legs shake during pets? It’s not because they like it.

Imagine this: You’re at the doctor’s office, and instead of one quick tap with the reflex hammer—the kind that makes your leg kick out without you meaning to—they just…keep going. Tap, tap, tap, right on that same spot below your knee, for a solid two minutes straight. It wouldn’t hurt you. But after a while, you’d probably start feeling pretty strongly about wanting it to stop—and if they didn’t, you might start wanting to kick someone on purpose.
