My dog can't hold its hind legs up, what's wrong? - briefly
If your dog is unable to hold up its hind legs, it could be due to degenerative myelopathy or a slipped disc, both of which require immediate veterinary attention. These conditions can lead to permanent paralysis if left untreated.
My dog can't hold its hind legs up, what's wrong? - in detail
If your dog is unable to hold up its hind legs, it could indicate several underlying issues that warrant immediate veterinary attention. One of the most common causes is degenerative myelopathy, a progressive disease affecting the spinal cord, often seen in older dogs. This condition typically starts with weakness and wobbliness in the hindquarters, eventually leading to complete paralysis if left untreated.
Another potential cause could be intervertebral disc disease (IVDD), which occurs when a disc in the spine ruptures or herniates, putting pressure on the spinal cord. This condition can lead to sudden and severe pain, as well as hind leg paralysis. In some cases, the dog may also exhibit a hunched back or an unusual gait.
Inflammation of the spinal cord, known as myelitis, can also result in hind leg weakness. This inflammation can be caused by various factors, including infection, trauma, or immune-mediated conditions. Neoplasia, or cancerous growths within the spinal column, is another serious concern that could lead to paralysis.
Additionally, neurological issues such as vestibular disease or idiopathic polyneuropathy can cause similar symptoms. Vestibular disease affects the inner ear and balance, often leading to a head tilt and unsteadiness, while idiopathic polyneuropathy is a degenerative condition affecting multiple nerves throughout the body.
Lastly, orthopedic issues such as hip dysplasia or luxating patella can cause discomfort and may affect the dog's ability to support its weight on its hind legs. However, these conditions usually present with different symptoms and are less likely to result in complete paralysis of the hindquarters without prior signs of joint pain or mobility issues.
Given the range of potential causes, it is crucial to consult a veterinarian promptly. They can perform a thorough physical examination, including neurological tests and possibly diagnostic imaging such as X-rays or MRI scans, to determine the underlying issue accurately. Early diagnosis and appropriate treatment can significantly improve your dog's prognosis and quality of life.
