I don't know much you can do about her curled toes now, since its been awhile..
You might want to call a vet and just ask if there is anything you can do....
You may not want to spend the money, but they could give you some info that
would be helpful.... but then maybe not..
If you have the time, try soaking them for 15 minutes a day and see if you can relax the
toes by just moving them a little bit, massage the joint , but not so that it causes her pain....
maybe the warm water would help..... I don't know.... that's what I would try.
Where was the break....? Did it heal up properly...?
