Is her hearing OK?
ETA, it can be hard to see that a dog is deaf, as they are brill at using thier other senses. They can tell when somebody is at the door, either by other dogs/peoples reactions of when somebody has entered by smelling the air that comes in. Things being dropped on the floor can be felt as vibrations through the floor (equally for a person/animal walking into a room). When the fridge has been opened a deaf dog may still come and see what you are doing - they can smell it. People/things outside can cause shodows/reflections/light effects that can be seen. so can be reacted to as if the dog could hear them. Fireworks can still cause a dog to react - if they can see the firework (and have allready made the association between the look of one and the sound of one while they could hear).
They can also follow most commands - if they see the facial expressions/body language that has always accompanied them, however, with a dog that does not know you, they would not know what the usual expressions/body language for commands are.
Our last dog must have been deaf for well over a year before we realised, we thought he'd just been getting stubborn! Cutting a long story short, we found communicating through body language/facial expressions, sooooo much better than vocaly, so when we got Buster as a pup, all commands were taught with a vocal & a signal.
