There are a few things that could be wrong with your dog. She could have suffered a stroke, injured her spine, or pinched a spinal nerve. It's also possible that she has developed a tumour somewhere along her back that's begun to press into her spine, causing temporary paralysis. Regardless of the cause your dog's condition is serious, and she should be taken to see a veterinary surgeon as soon as possible.
Given that it doesn't seem like you're aware of any injury to your dog, she's most likely to be suffering from a pinched or pressured nerve. When a canine spinal nerve is compromised in such a manner, it not only limits your dog's ability to move, it causes gradual damage to the compromised nerve. A completely damaged nerve could permanently paralyse your dog. One way to tell if the nerve has reached that stage is to lightly test your dog's pain tolerance by applying pressure to her infirm feet. Her reaction will be a sure sign that the nerve still retains some function.
Don't take that as a good sign though; it means that your veterinary surgeon will have a greater possibility of repairing the issue, yes, but only if they're able to see your dog soon. Even the most gifted vet might not be able to salvage a nerve that's reached its damage threshold.
If your dog is exhibiting behavioural changes or showing signs of confusion or depression, is lethargic, and/or is exhibiting a head tilt, then it's possible that she's suffered a recent stroke. If so, a vet should be able to diagnose the cause of your dog's stroke and assist you in developing a therapy plan. It can take weeks for a dog to recover from a stroke.
Finally, your dog could have suffered a spinal injury while you weren't paying attention. Check for any external signs of injury and survey the area in which you found her. Dogs can recover from such injuries, but it will require time, patience and surgery.
