She needs to be seen by a VET and you need to block off that balcony, or the bottom of it with boards, screen, etc.
What are you waiting for, your dog is in pain, get to the vet ASAP.
Don't make her walk or try to move!!!!!! You can do more damage to the injury.....Please get her to an Emergency Vet Hospital, Now! Clearly, she has done some serious damage from the fall.....There's too many possibilities to list.....Whatever she has pulled, sprained, or broke, needs to be taken care of.....She needs medical attention & pain management just as a human would.....The Vet will prescribe the proper meds. & dosage....
It is your responsibilty as a pet owner to seek treatment for her.....Get going.......I hope she's alright, but I fear the worst..........Please come back and let us know what happened......Karla
