Paralysis in senior pets can be caused by various underlying conditions, ranging from degenerative diseases to traumatic injuries. Some common causes of paralysis in senior pets include:

Degenerative Myelopathy: This is a progressive disease of the spinal cord that primarily affects older dogs, particularly certain breeds like German Shepherds, Boxers, and Corgis. Degenerative myelopathy typically starts with weakness in the hind limbs, leading to paralysis over time.

Intervertebral Disc Disease (IVDD): IVDD occurs when the discs between the vertebrae of the spine degenerate or herniate, causing compression of the spinal cord. This condition is more common in certain breeds with long backs, such as Dachshunds and Basset Hounds, and can result in paralysis if left untreated.

Traumatic Injuries: Accidents or trauma, such as being hit by a car or falling from a height, can cause spinal cord injuries leading to paralysis. Older pets may be more susceptible to injuries due to decreased agility and coordination.

Cancer: Cancerous tumors in the spine or nervous system can cause compression of the spinal cord, leading to paralysis. Senior pets are more prone to developing cancer, which can affect various parts of the body, including the spinal cord.

Stroke: Just like humans, pets can experience strokes, which occur when blood flow to the brain is disrupted. Depending on the location and severity of the stroke, it can lead to partial or complete paralysis.

Neurological Disorders: Various neurological conditions, such as vestibular disease, meningitis, or encephalitis, can affect the central nervous system and result in paralysis or weakness in senior pets.

Infectious Diseases: Infections such as tick-borne diseases (e.g., Lyme disease) or viral infections (e.g., canine distemper in dogs, feline infectious peritonitis in cats) can sometimes lead to neurological symptoms including paralysis.

It’s essential to seek veterinary attention promptly if your senior pet experiences sudden onset paralysis or weakness, as prompt diagnosis and treatment can significantly impact their prognosis. A thorough examination, including diagnostic tests such as X-rays, MRI, or CT scans, may be necessary to determine the underlying cause of paralysis and develop an appropriate treatment plan.
