My car sounds like it’s dragging something but when I look under it there’s nothing there. The sound it makes is comparable to the sound a snow plow makes as its plowing the road. The sound is constant but gets worse when I brake. Anyone have an idea of what could be the cause?
Offhand, I might urge you strongly to have the brakes inspected as that noise could be a brake pad that is worn down to nothing.
After that, some possibilities could be a bent brake rotor shield or exhaust heat shield rattle.

An immediate brake inspection is the way to go, without question.
However, if the brakes turn out to be okay, then my next suspect would be a fender liner that has become dislodged and is rubbing on one of the tires.
I once had a noise that sounded just like something dragging , it was a wheel bearing .
“I once had a noise that sounded just like something dragging , it was a wheel bearing .”
Sloepoke has a good suggestion, particularly a front wheel bearing that has been going south for a while, which would get louder while braking, as described.
Does the noise change (in volume or pitch) when you go around a fairly tight curve, either right or left, or when making a lane change where a change of direction is required?
It doesn’t sound like a wheel bearing symptom to me, but if it gets considerably louder the faster you go, that would be consistent with a wheel bearing related symptom. Another idea, the brakes may be dragging for some reason, possibly the parking brakes. Do any of the wheels get hot after a 2 or 3 miles drive with little to no braking during the trip? I had a dragging sound occur on my truck, and that turned out to be a problem in the rear differential. That sound got considerably worse when turning vs going straight.
Mine was a right front wheel bearing . I actually stopped the car & looked under it to see what was dragging before pinpointing the problem .
Another suggestion is one of covers underneath the car. I have seen them dragging while a car is going down the road when the wind catches them. If a couple of the pins are broken the wind can pull them down and they drag the road. My first guess would be brakes though.
