Siome causes of dog paralysis include genetic defects, polymyositis, polyneuritis, tick infection and tumors, according to PetMD. Other causes include slipped back discs, meningomyelitis and distemper. Canines are also susceptible to a variety of bacterial and viral infections that cause paralysis.
Certain breeds are genetically prone to conditions that lead to canine immobility, notes PetMD. For instance, German shepherds, Chesapeake Bay retrievers and boxers are genetically predisposed to canine degenerative myelopathy, which is a condition that affects the spinal cord and bones of the animal. Injury to the spine can cause paralysis, including abnormalities of the spinal cord. Inflammation or infection of the spine can cause the same problem.
Blockage within the spine and other parts of the body can foster complications, according to PetMD. Embolus creates blockage in the spine, and aortic embolus slows blood flow to the hind legs.
Different types of microbes attack various parts of the body and cause paralysis, reports PetMD. The toxins produced by botulism affect dogs in a harmful way. A sickness known as discospondylitis targets the vertebrae. Meningomyelitis is another bacterial or viral malady that infects the brain, causing the nerves to miscommunicate.
Muscle conditions can cause canine paralysis, claims PetMD. Myasthenia gravis is a condition that severely weakens the muscles. Polymyositis leads to inflammation within the muscles.
