Were there any open tooth holes?
Have you kept them open?
Allowing a bite to close over too soon traps bacteria inside the wound and creates a pocket for infection to fester.
Have the wounds been cleaned and scrubbed since the initial cleaning?
About the attack:
Do you know the size of the dog that attacked her?
Did you witness the attack?
Do you know if the dog t-bone her or caught her from behind?
If the dog “had her good” there should be at least FOUR areas of injury from the upper and lower canines and potentially corresponding scissor cuts from the sharp outer edges of the molars.
The larger the dog the greater the distance between them.
Also the larger the dog, the greater the bite force psi, due to leverage effect.

I’d re-clean the wounds and do a second inspection.
So this is what we know so far: there are external injuries from a dog attack and the bird is weak and unable to walk.
But we don’t know the answers to these:
Potential internal infection?
Potentially internal crushing injuries?
Potential pelvis, hip, leg fracture?
I also have to add, although the girl didn’t make it, this was an excellent post @staceyj
