Neurological disorders affecting a dog's back legs often cause weakness, incoordination (wobbling), and paralysis, with common culprits including Degenerative Myelopathy (DM), which mimics arthritis and affects older dogs; Intervertebral Disc Disease (IVDD), a spinal disc issue; and less commonly, spinal tumors, lumbosacral disease, or myasthenia gravis. Key signs are scuffing nails, dragging paws, difficulty rising, and wobbling, progressing to incontinence and paralysis, making prompt vet consultation crucial for diagnosis via MRI/CT/spinal taps to rule out other causes.
