Why can't my dog use her back legs all if the sudden. She also doesn't understand curl her body. Not trauma. No falls. No blood. No spinal or limb pain.

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. If Lady is unable to use her back legs, this could still be a back injury. Many times, there is no pain with a protruding spinal disc. The protrusion can lead to compression on the spine causing loss of limb function. Depending on where the protrusion is will determine what limbs are affected. Neuromuscular diseases such as degenerative myelopathy, myasthenia gravis, myopathy, etc. can lead to paralysis or weakness. I would recommend having a veterinarian examine Lady so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.
