Why is my senior dog dragging a hind leg and walking sideways?
This indicates that she has some degree of damage to the spinal nerves or peripheral nerves that control that leg. This can happen when they are hit hard by something, or (more likely) when they have a lower-spine disease. Old dogs tend to be more susceptible to various spinal cord problems that develop with age.
These can be treatable though, so it's best to take Trixie for a vet evaluation sometime soon. The vet will be able to narrow-down the cause of this problem and provide pain relief (these conditions are usually very painful).
For now, it's best to restrict her activity, as this can worsen her condition. Do not allow her to run, jump, or go on long walks until advised otherwise by your veterinarian.
I hope that helps and Trixie gets better soon.
