Hognose snakes are frequently confused with Pygmy rattlesnakes - Rattlersnakes do not hiss at all, so if the snake you see hisses it is most likely a Hognose snake and harmless.

Comparison: Pygmy Rattlesnake &  Hognose Snakes

The tip of the Pygmy Rattlesnake snout is blunt and rounded; pupil of the eye is a catlike vertical slit; and there is a pit on the side of the head between the eye and nostril. Tail end is often a sulfur color.
