does not completely recover the initial muscular capability but still is able to live for years. In very bad cases, breathing can be impaired, and unless the dog is placed on a ventilator, suffocation will occur. Polyradiculoneuritis has also been seen 1-2o weeks after vaccination in dogs and cats. It can also be caused by toxoplasmosis. Rottweiler distal sensorimotor polyneuropathy is characterized by distal muscle denervation, but the cause is unknown. It affects young adult Rottweilers. The symptoms include weakness of all four legs and decreased reflexes. The disease is gradually progressive. Treatment is possible with corticosteroids, but the prognosis is poor. Sensory neuropathies are inherited conditions in dogs and cause an inability to feel pain and a loss of proprioception. Self-mutilation is often seen. No treatment has been found, and the prognosis is poor in severe cases. Several breeds are affected: Boxer symptoms usually occur around two months of age as a slowly progressive disease. Dachshund (longhaired) disease usually occurs between 8 and 12 weeks of age, and causes urinary incontinence, loss of pain sensation all over the body, and penis mutilation. It is probably inherited as an autosomal recessive trait. English Pointer illness usually occurs between the ages of 3 and 8 months and most commonly involves licking and biting at the paws. No treatment is known and a poor prognosis is given. It is inherited as an autosomal recessive trait. Spinal muscular atrophy occurs in cats and dogs, and is caused by the death of nerve cells in the spinal cord. This progressive disease has no known treatment and a poor prognosis. Affected dog breeds include the Swedish Lapland Dog, Brittany Spaniel, English Pointer, German Shepherd dog, Rottweiler, and Cairn Terrier. Maine Coons are one of the affected cat breeds. Tick paralysis is an acute, ascending motor paralysis that occurs in dogs and cats. The cause is a neurotoxin in the saliva of certain species of adult ticks. Dermacentor species predominate as a cause in North America, while Ixodes species mainly cause the disease in Australia. The onset of symptoms is 5 to 9 days after tick attachment, and include incoordination progressing to paralysis, changed voice, and difficulty eating. Death can occur secondary to paralysis of the respiratory muscles, but in North America, a good prognosis results once the ticks are removed. Recovery is usually in 1 to 3 days. In Australia, however, it is a more
