Have you added Glucosamine and Chondroitin supplements? It really helps. My older dog, Greta, fractured her hip when she was a pup. She is nearly eight years old now. Her hips always grind and pop and we help her into the car, etc. She takes Rimadyl, but I waited until this last year to give it to her regularly, because I was afraid if given to her since puppyhood it may damage internal organs.
Is it OK to give dogs Motrin? I haven't heard that before, but some people give them enteric-coated aspirin as it does not harm the stomach like regular aspirin.
So, she is five years old now? I've sometimes thought that if Greta some day loses the use of her hind legs we can get one of those doggie wheelchairs for her. I saw an ad for one in the back of "Dog & Kennel" magazine.
I hope things get better for you and you find some options.
Sometimes I put a hot water bottle on Greta's hips. Also, I think swimming is good for her, too...less friction than running, etc. But, you may want to ask your vet about the specifics. I may not know what I am talking about in relation to your individual dog.
