Well the good thing is that you had a soft landing and not a hard one to break a hip.

Do contact your doctor. You may need a support device and the doctor should be able to figure out what would work best. Plus there may be other accomodations that can be made in your home to help you stay independent and safe for as long as possible.

I am sure it is hard living alone and having these issues.

Your dog loves you and wants you to take very good care of you, so you can take good care of him/her!! Feel better soon.
