I took Molly to our regular vet tonight to have her foot examined again and to have x-rays done. For my own peace of mind, I really wanted x-rays done so that I could stop worrying about bone cancer or a (stress) fracture.
The story has not changed. Molly has arthritic changes from her hard driving, rockstar lifestyle and there really isn't much to be done except rest her for a while, manage the pain, and hope for the best.
I feel sad.
