The dog suddenly lost its hind legs, what could it be? - briefly
The sudden loss of a dog's hind legs can be attributed to several causes, including trauma from an accident or injury, neurological issues such as intervertebral disc disease (IVDD), or in rare cases, autoimmune disorders like immune-mediated polyneuropathy. It is crucial to seek immediate veterinary attention for a proper diagnosis and appropriate treatment.

The sudden loss of hind legs in dogs can be attributed to several causes, each requiring prompt veterinary attention.
One potential cause is trauma or injury. A severe impact, such as being hit by a vehicle, falling from a significant height, or sustaining a deep cut, can result in the immediate loss of limbs. In these cases, bleeding and visible damage are typically present.
Another possible reason is degenerative myelopathy, a progressive neurological condition that primarily affects the hindquarters. This disease begins with weakness and uncoordinated movement in the hind legs, eventually leading to paralysis. While it starts gradually, the onset can be sudden in some cases.
Intervertebral disc disease (IVDD) is another serious condition that can cause sudden hind leg paralysis. This occurs when a disc in the spine herniates or ruptures, putting pressure on the spinal cord and nerves. IVDD is more common in certain breeds like Dachshunds and Beagles.
Degenerative lumbosacral stenosis is another neurological condition that can cause hind leg weakness and paralysis. This condition results from a narrowing of the spinal canal, which puts pressure on the nerves. It is more common in older dogs and large breeds.
Toxicities or poisoning can also lead to sudden hind leg paralysis. Certain substances, such as ethylene glycol found in antifreeze, can cause neurological symptoms if ingested. Prompt treatment is crucial to prevent permanent damage.
Lastly, certain types of cancer, particularly those that metastasize to the spine or affect the nervous system, can cause sudden paralysis. While less common, it is essential to consider this possibility during diagnosis.
In conclusion, the sudden loss of hind legs in dogs can be due to a variety of causes, including trauma, neurological diseases, toxicities, and cancer. Early veterinary intervention is critical for accurate diagnosis and effective treatment.
