A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
English: This image shows an example of affected areas to represent the differences between paraplegia (left), hemiplegia (middle), and quadriplegia (right). Please note these areas may differ for each condition and are dependent upon the neurological level of injury.
Fortunately, veterinary medicine and medical devices have come a long way, and wheelchairs for dogs are more accessible than ever to the four-legged patients who need to use them.

The difference in size and proportion between some breeds are as great as those between any wild genera, but all dogs are clearly members of the same species. [5] In 2010, a study of dog skull shape compared to extant carnivorans proposed that "The greatest shape distances between dog breeds clearly surpass the maximum divergence between ...
