arms or legs?

are the front "arms" of a dog called "legs" or "arms"? technically, the part of the "front legs" of a dog which bends is called an "elbow" and the "rear legs" part is called the "knee". so, if that is the case, dogs have 2 arms and 2 legs. so, is it innaccurate to say that dogs have 4 legs?

consider yourself blessed if you have 2 arms and 2 legs. enough said.
