It is a spinal and vertebral birth defect. It basically means that one or more of the vertebrae in your dog's spinal cord has not developed into a full vertebra and looks like a wedge instead. This is not uncommon in pugs and seems to also be related to the way their tail curls, ie it often happens in small brachycephalic dogs with a screw tail.. Unfortunately the condition can affect the nervous system in that it can affect the pelvic limbs and can also lead to progressive spinal cord compression. Treatment can be very expensive as in the latter case neurosurgery by a specialist surgeon may be necessary.
