my little stove top sophers

I found out today that my youngest rescue dog has mild hip dyspepsia. She has been so stiff for the last few months and it has been happening more and more. So today when I took them to their yearly vet visit, I asked the vet about. She did x-rays and what she found I almost cried. it looked like her mom was not eating right when she had her and it caused  sophies hips to deform and splinter. She is almost two years old and its only mild for now. I started her on a joint medication and pain pills. I am trying to find alternatives to the pain pills but mostly I just want her to not be in pain.
